DeepL completes SOC 2 Type II report, further enhancing security and confidentiality

What you need to know about SOC 2 Type 2 reports and DeepL:

  • A SOC 2 Type II report evaluates a company’s information systems regarding security, availability, confidentiality, processing integrity, and privacy
  • This report illustrates DeepL’s continued dedication to world-class data protection and security
  • DeepL’s full SOC 2 Type II report can be accessed via request here

Does your company have specific security requirements for all the tools and vendors it works with? If you answered yes, good—you should. From GDPR to ISO 27001, there are many important data security and privacy measures you need to take into consideration.

On that note, we have great news. DeepL now has another qualification to add to its growing list: the SOC 2 Type II report. This extensive auditing procedure provides the proof that security-conscious organizations need when choosing which tools and service providers to work with.

Want to learn more about what this is, why it’s important, and how you can access DeepL’s report? Read on.

What is a SOC 2 Type II report?

an illustration of the Soc 2 type 2 five trust service principles

The Service and Organization Controls (SOC) 2 Type II report was ​​developed by the American Institute of Certified Public Accountants (AICPA), based on the Trust Services Criteria (TSC), as a way to define proper customer data management. 

The purpose of the SOC 2 report is to evaluate information systems of a company or organization based on five “trust service principles”, which are:

  • Security: this is a critical principle for all companies or organizations that deal with sensitive or confidential information. For DeepL, this means that we put controls in place to protect against theft, unauthorized access, or destruction of our systems and data.
  • Availability: this principle is vital for companies that rely on their systems and data to conduct their day-to-day business operations. At DeepL, this means we use controls to maintain the consistent availability of all our systems and data. 
  • Processing integrity: critical for organizations that rely on accurate data to make business decisions, meeting this principle requires controls be put in place to ensure the accuracy and completeness of data processing.  
  • Confidentiality: this principle is necessary for organizations that handle sensitive data and information. At DeepL, it means we introduce controls to safeguard the confidentiality of our systems and data. For example, the SOC 2 Type II audit verified that we never store any DeepL Pro translation data—effectively maintaining the full confidentiality of users’ data.
  • Privacy: this principle is critical for organizations that collect, process, or store personal information, and refers to controls put in place to protect the privacy of personal data.

According to Maximilian Ehrlich, DeepL’s Information Security Officer, it’s important to note that “each SOC 2 Type II report is unique to the organization and, therefore, reflects its own designed controls in accordance with its business objectives, risks, and adherence to the trust service criteria.” 

As the SOC 2 Type II report provides critical information on how customer data is managed, it must be issued by an outside auditor. It’s the job of this auditor to assess how well the company or organization in question is complying with the five trust principles defined above.

How is a SOC 2 Type II report different from a Type I report?

If there’s a SOC 2 Type II report, there has to be a Type I, right? Indeed, there is—and there are some important distinctions between the two. 

The main difference between the Type I and the Type II report is that the Type I describes the existing controls of a company. On the other hand, the Type II requires that an independent auditor checks the described controls.  

According to Ehrlich, the Type II report proves that “the predefined policies and procedures have been successfully followed for a reporting period of 12 months", which is verified by a third party. Therefore, the Type II report serves as a much stronger testament to existing security controls than a Type I report. 

Why are SOC 2 Type II reports important?

While not every company requires their partners and service providers to have passed their SOC 2 Type II report, the most security-minded organizations do.

Successfully completing the SOC 2 Type II audit is a rigorous, extensive undertaking. Thus, having this report is a clear sign to all potential partners, suppliers, and clients that your company prioritizes data security and privacy—and you’ve put in the work to prove it. 

At DeepL, data security, privacy, and data protection are of the utmost importance—which is why we’re so pleased to share that DeepL has passed its independent SOC 2 Type II audit of its Pro service, conducted by a Certified Public Accountant (CPA).

Here, Ehrlich perfectly captures DeepL’s shared sentiment, stating: “We are proud to announce our SOC 2 Type II report as further evidence of DeepL’s commitment to security and validation of our security measures."

How to choose the best machine translation tool for your business

What you need to know about choosing machine translation software: 

  • Choosing the right machine translation tool is vital to a strong localization strategy 
  • Important considerations include data security and document format handling  
  • The right AI translation tool can improve ROI and increase localization cost efficiency 
  • Discover translation and localization best practices by downloading our report  

How many languages does your company operate in? Probably quite a few. As the global marketplace becomes increasingly interlinked, communicating in multiple languages is a necessity for businesses to thrive. This is where translation and localization come in, allowing companies to authentically connect.  

However, 87% of marketers from our recent study stated that having to translate content into multiple languages can be both costly and difficult. Cue machine translation—which makes a big difference by offering an accurate, efficient, and cost-effective method to localize companies' content. But choosing the right machine translation vendor is not a decision to be taken lightly, as it can have a significant impact on your company's localization strategy and overall workflow.  

In this blog post, we’ll explore some of the key considerations when selecting the best machine translation tool for your organization. Remember, with the right choice, your business not only benefits from accurate translations, but also from a seamless, secure, and efficient localization process.  

What should you consider when choosing a machine translation service?

With the help of Regina Corso Consulting, DeepL recently conducted a survey of marketers in the United States, France, Germany, and Japan—specifically targeting those responsible for translation and localization. With the results of this survey, we created the report: The state of translation and localization in 2023-2024: insights, challenges, and opportunities.   

Thanks to this research, we discovered a host of helpful insights. For example, 75% of respondents agreed that localized content significantly boosts customer engagement—while a staggering 96% reported positive ROI (return on investment) from localization efforts.   

Clearly, localization has a significant business impact—meaning that selecting the right machine translation software is critical. According to our research, the most important considerations include:  

  1. Document format handling: 23% of respondents noted the importance of a vendor's ability to handle various document formats, such as XML, HTML, etc.  
  2. Data security: 20% of respondents highlighted the critical role data security plays in the selection process. Clearly, how companies ensure the protection and privacy of their and their customers' sensitive information—think data encryption, ISO 27001-certified data centers, and GDPR regulations—is important. 
  3. API offerings: 20% of marketers surveyed indicated that the availability of an application programming interface (API) is an important consideration. After all, APIs are ideal for integrating translation services into existing workflows, streamlining operations, and improving efficiency. 

Interestingly, 80% of respondents work in the technology industry. This may indicate that the importance of the above considerations is impacted by the specific needs of tech companies, where document translation, data security, and API availability play a greater role.  

How are companies working with machine translation vendors?  

There’s more than one way to work with—and benefit from—a machine translation tool. Our survey revealed three different approaches that marketers are using to work with machine translation vendors:   

  • 44% work with a technology partner who uses the vendor 
  • 33% partner with an agency that employs the vendor's services 
  • 23% contract directly with the vendor 

How do these options affect your business? 

Illustration showing machine translation technology choices with layered web pages and arrows

Our findings surrounding the use of machine translation suggest a trend toward collaboration, with most marketers opting to team up with experts. With this in mind, businesses should consider the benefits of using a technology partner/agency versus contracting directly with a machine translation vendor. 

On the one hand, opting for a technology partner or agency allows companies to benefit from their expertise and existing relationships with vendors. On the other hand, working directly with vendors is a better choice for those seeking increased control over the translation process and a more cost-effective solution.  

For this option, DeepL is an ideal choice—as its accurate, efficient AI translations help to streamline the localization process. 

Want a deep dive into translation and localization? 

Choosing the right machine translation vendor is just one step in the translation and localization journey. With the help of the right tool, your company can streamline localization workflows and operate more efficiently.

Navigating the challenges of content localization in 2023-2024: Industry insights and practical solutions

What you'll learn in this summary of our localization report: 

  • Why translating and localizing content is a sound investment 
  • How localization increases important metrics like customer engagement 
  • How DeepL’s AI translation can help streamline your company’s localization process 

Localization—not to be confused with translation—is the practice of adapting products or content to local languages and cultures. Essential for businesses looking to expand their global reach, content localization allows companies to reach consumers where they’re most comfortable: in their native language.  

Recently, DeepL partnered with Regina Corso Consulting to survey marketers in France, Germany, Japan, and the United States who are responsible for translation and localization at their companies. Using the results of this survey, we created the report, The state of translation and localization in 2023-2024: insights, challenges, and opportunities.  

In this blog post, we’ll summarize some of the survey’s key findings and explore why localization is one of the most important investments for global companies. Then, to learn why DeepL’s AI translation tool is the ideal helper to speed up localization processes, you can access our full report

The survey: objectives and scope 

illustration showing a content localization strategy with a page and bar graphs


The study—targeted at director-level marketers in companies with over 100 employees—had three main objectives:  

  1. To learn more about how these marketers approach translation and localization at their companies 
  2. Find out if they use machine translation and AI-writing tools in their workflows 
  3. Understand the challenges they most commonly encounter 

Below, you’ll find a selection of the main insights that we uncovered. 

The ROI of localization 

For businesses to succeed in international markets and drive growth, they need to create multilingual content—which is why localization plays such an important role in global expansion.  

For this report, we wanted to find out, more specifically, how localized content impacts return on investment (ROI). Here’s what we discovered: 

Key insight: An overwhelming 96% of respondents reported a positive ROI from localization efforts, and notably, 65% reported an ROI of 3x or greater. 

Why it matters: For companies that aren’t sure if they should allocate resources to localization, these figures offer compelling evidence to do so. 

The rise of AI in content creation 

Illustration showing how AI content creation helps businesses connect with the right target market


AI’s role in content generation has been expanding over the past months. An interesting trend that’s reshaping the localization process, we wanted to know how prevalent the use of AI tools is with today’s marketers.  

Key insight: AI-assisted writing tools are used by 77% of respondents, and machine translation by an astonishing 98%. 

Why it matters: This isn't a passing trend; it’s the new standard. Businesses slow to adapt risk being overshadowed by those who have integrated these technologies into their localization efforts. 

Increasing engagement through localization 

Many marketers wonder if investing in localization is worth the time and effort. What tangible benefits does it boast for businesses to localize new and existing content? 

Well, according to our research, increased customer engagement is high on the list.  

Key insight: 75% of respondents agreed that localized content significantly boosts customer engagement. 

Why it matters: Engaged customers are more likely to become repeat customers, refer your business, and spend more money on products and services. 

The value of human oversight 

Illustration of a magnifying glass showing translation and localization tools that help communicate with a target audience

Even as AI tools become more advanced, human involvement will remain an integral part of a successful content localization strategy. Machine translation isn’t perfect, and a human-in-the-loop approach is the key to success.    Incorporating human review allows companies to ensure all content adheres to their style and quality guidelines. 

Key insight: 99% of respondents supplement machine translation with human review. 

Why it matters: This underscores the need for a balanced approach that incorporates both technological and human expertise for high-quality outcomes. 

The strengths and weaknesses of machine translation 

While machine translation can speed up the localization process, it still has some weak spots to keep in mind. 

Key insight: A significant 82% expressed concerns about accurately translating industry-specific terms. 

Why it matters: For industry-specific jargon and vocabulary, companies should consider training custom machine translation models or selecting a machine translator that comes with a glossary feature.

Unlock the power of AI for law: Five revolutionary tools for the legal profession

What you need to know about: 

  • Choosing best AI tools for legal professionals 
  • How to find a secure tool and why it matters 
  • Useful features for law practice 

If you work in the legal industry, you’ve probably been eyeing the most recent wave of AI adoption with a mixture of interest and apprehension. Are you anticipating (or dreading) the slew of lawsuits that are sure to arise from AI use and misuse? Or wondering how AI will impact your own daily work? Ultimately, as technology evolves, the law needs to keep pace—and with it, legal professionals.    

Whatever your view on AI, it’s here to stay. In this article, we’ll explore five of the most game-changing AI tools transforming the legal profession and how they can benefit your law firm. If you’re not using these tools already, we can guarantee that your competition is!     We'll also fill you in on how to vet AI tools suitable for the practice of law and let you know which AI features are most useful for lawyers today.

Tedium ad nauseam: Why law firms are adopting AI

Illustration of several documents on a blue background. DeepL translation helps lawyers save time by translating documents instantly.

Not even the often traditionalist field of law is immune to the rise of artificial intelligence. In fact, AI is already becoming a linchpin in the legal field, allowing lawyers to work more efficiently and provide better service to their clients.

AI-based tools can help law firms stay competitive in a constantly evolving global market. Dr. Axel Freiherr von dem Bussche, LL.M. (L.S.E.), CIPP/E, Partner at Taylor Wessing, weighs in:  

Using AI and technology-enabled tools in the legal sector is becoming increasingly important to remain competitive and improve efficiency. These tools can assist lawyers with legal research, document review, and contract analysis and translation, freeing up time for more complex and strategic work. They can also provide valuable insights and help lawyers make more informed decisions, leading to better client outcomes.

The bottom line for many lawyers? AI tools can take over some of the mundane and tedious tasks legal professionals dread, freeing up time for more high-value work (and removing a few headaches along the way.)  

Let’s take a closer look.  

Five powerful AI technologies for legal professionals 

Scales holding two sides of DeepL’s translator tool to illustrate the importance of accurate translation in the legal profession.

1. AI-powered translation  

The legal industry is already complex, but when you add international clients and colleagues to the mix, things can get even more complicated. Practicing international law requires an understanding of diverse legal systems and cultures, as well as the ability to keep up with constantly evolving laws and regulations. This can be particularly challenging when there's a language barrier. 

As the legal industry continues to become more globalized, law firms are working with an increasing number of international clients. According to a Maia Research report on legal translation software, there is a growing demand for legal translation services, which is currently experiencing 13-15% year-on-year growth. 

With AI translation, legal teams can: 

✅ Translate legal documents faster 
  • Translate legal documents such as contracts, briefs, and court filings for clients  
  • Quickly create bilingual or foreign-language contracts (legally operable) 
  • Save time and resources with accurate and consistent translations  
✅ Communicate smoothly with international teams and clients 
  • Clarify legal terms and give legal advice via email   
  • Submit cases in foreign languages to local authorities (legally operable)  
✅ Research foreign laws and regulations
  • Understand and comply with legal requirements in different countries  
  • Build a foundation as a global player in the market  
✅ Provide multilingual legal advice 
  • Serve clients who speak different languages  
  • Improve client satisfaction and loyalty  
✅ Ensure consistency of legal translations across the organization 
  • Use custom glossaries to save editing time and guarantee consistency in official communication across multiple languages  
Illustration showing a contract translated into several languages on a pale yellow background. Contract translation is one use case of DeepL for lawyers.

AI-powered translation tools are useful for providing legally operable translations, such as bilingual contracts, and convenience translations like client communications. However, it's important to note that AI translation shouldn't completely replace human translators. Some official documents require certified or notarized translations that can only be provided by a certified human translator.   

For example, when a client is applying for citizenship in a foreign country, they often need to provide a certified translation of their birth certificate and other identification documents. To ensure accuracy, "human-in-the-loop" workflows are crucial to approve AI-generated translations. According to Gartner, solutions that combine staffing and software will account for 30% of all new legal tech automation offerings through 2025. 

2. AI-powered knowledge management systems 

AI-powered knowledge management systems have revolutionized the legal industry, giving lawyers lightning-fast access to critical information. With these powerful tools, legal professionals can quickly search through vast amounts of data, identify patterns in legal documents, and stay on top of changes in laws and regulations. Best of all, these systems automate tedious processes such as document categorization, saving valuable time and increasing productivity.   

Not surprisingly, the use of AI-powered knowledge management systems is on the rise among legal professionals.  

3. AI contract analysis and management 

One of the key areas where AI is making an impact on legal work today is in contract analysis and management. These tools automate mundane tasks such as document review or tracking deadlines for signed agreements. Lawyers can use AI-driven systems to quickly review contracts and identify potential issues, such as risks associated with certain clauses. These systems also store contracts centrally, making them more accessible and automating error notifications. 

AI-enabled contract management tools also provide insights into past cases to help minimize disputes arising from noncompliance with laws or regulations. Natural language processing algorithms are used to detect discrepancies in existing contracts and to suggest ways to mitigate risks. This helps law firms ensure they provide the best service to their clients while remaining competitive in the market. 

4. Generative AI for document creation 

In the legal field, generative AI is offering a new level of efficiency for document creation. This process entails using AI algorithms to generate documents from templates and structured data sets, as well as analyzing contracts for potential risks or discrepancies. By automating these tedious tasks, lawyers can save time and money while helping their firm remain competitive in the world of advancing AI. 

AI-powered document creation also helps reduce errors and spot mistakes quickly—allowing attorneys to better protect their clients' interests during negotiations by identifying potential issues before they become problems down the line. As a result, lawyers can provide more personalized services that meet their clients' needs faster than ever before. 

5. Chatbots for client intake 

Chatbots are a valuable first point of contact in the client intake process. AI-powered chatbots provide general advice to clients and understand complex questions using natural language processing, directing clients to the information they need instantly. 

Chatbots offer 24/7 availability, quickly answering inquiries and FAQs, reducing wait times, and enabling staff members to focus on more detailed queries. Using AI-powered chatbot technology saves time and resources while providing better customer service.

A word to the wise: safe and ethical AI use 

However helpful these tools may be, implementing AI technologies isn't to be taken lightly, as there are certain risks associated with using AI. It's important for firms to understand the implications of deploying AI technologies and make sure that the technology is implemented responsibly. This means establishing protocols regarding data privacy and security when dealing with confidential client data.

Firms should also consider how to use AI responsibly and ethically, such as taking steps to audit machine learning models for bias or instituting a policy that requires the use of AI to be monitored and supervised by a human.

How to evaluate the security of AI tools for the legal sector

A document with a signature and stamp, with the DeepL logo in the forefront, displaying the security of DeepL’s AI translation tool.

Lawyers must be aware of the evolving legal requirements for AI to give sound counsel regarding its use and to guarantee that the tools they use in their work are foolproof.

Here are some security hallmarks to look out for:

GDPR compliance  

The General Data Protection Regulation is a stringent security and privacy regulation. It affects businesses that pursue or store data pertaining to people situated in the European Union. Artificial intelligence that abides by the GDPR requirements can be relied on to honor and safeguard confidential information.


Data encryption scrambles information to create a code that can only be unlocked using an individual password or key. This makes it far more difficult for any unauthorized individuals to access the data. Regulations like GDPR demand that encryption is used to ensure personal information is kept secure.

SSO and/or 2FA 

Single sign-on (SSO) allows users to access various programs and systems with only one set of credentials, eliminating the worry of weak passwords or forgotten login details. This not only saves time, but also helps to secure confidential data from unauthorized access.  

Two-factor authentication (2FA) adds an extra layer of security by requiring users to provide two forms of authentication, such as a password and a verification code sent to their phone, before accessing their accounts. This reduces the risk of account takeover and prevents unauthorized access to confidential information.

ISO 27001 certification

ISO 27001 is an international standard that helps businesses manage the security of their information systems. By partnering with an ISO 27001-certified provider, law firms can better protect their data and guarantee a high level of security. 

Valuable software features for legal professionals

Customer research carried out by DeepL in 2023 identified these features as particularly helpful for law firms.

✅ Integrations 

Does the AI tool integrate where the team is already working? 

✅ Onboarding 

How easy is it to start using this tool? How much time will it take to implement?

✅ Customization   

Is the AI trainable? Does it save and store data to customize the user experience?

How Deutsche Bahn, Weglot, and Alza used DeepL’s AI translation for more efficient localization

What you need to know about how DB, Weglot, and Alza used DeepL: 

  • Deutsche Bahn used DeepL to connect its global, multilingual workforce and ensure consistent, industry-specific communication 
  • Weglot's customers benefitted from DeepL API’s incredible accuracy and efficient translations, saving them time and money when localizing their content 
  • Alza integrated DeepL API to efficiently localize its website content into five different European languages, saving thousands of euros a month in operating costs 


Why AI translation is the best choice to streamline localization 

Localization isn't an easy process; it requires time, effort, and a great deal of expertise. However, there are ways to make localization easier and less time-consuming—namely, with AI translation. 

Great for localizing everything from your website content to customer support to marketing materials, an AI translation tool like DeepL allows companies to work more efficiently. With higher quality and more accurate machine translations that improve project alignment and lower costs, your company can get a leg up on the competition. 

But don’t just take our word for it—ask our customers. In this post, we’ll cover three case studies to see how real DeepL customers used AI translation to enhance their localization processes and take their businesses global. 

Deutsche Bahn x DeepL: connecting a multilingual workforce with consistent global communication  

Illustration showing a red DB train and the DeepL Pro logo over a bar graph

As the largest railway operator and infrastructure owner in Europe, Deutsche Bahn (DB) has employees all over the continent. Of its 320,000 full-time employees, only 64% are based in Germany—meaning communication across multiple languages is key to DB’s international success.  

Thankfully, DB has DeepL to enable seamless communication for its massive, multilingual workforce.  

To communicate at scale, DB knew that machine translation technology provided the best solution. However, the company had to overcome its main challenge: highly technical terminology.  

In order for employees with different native languages and professions to communicate clearly, the translation would have to account for industry-specific jargon, dialects, and idioms. That’s where DeepL’s glossary really came in handy. 

Since integrating DeepL, DB has added more than 30,000 entries to its glossary, allowing DB employees to communicate consistently across the organization. With the power to specify their own translations for words and even entire phrases, DB ensured the use of industry and company-specific vocabulary in all communications. 

Additionally, DeepL’s glossaries rely on morphosyntactic terminology integration—meaning that DeepL adapts the formulation of translations based on glossary entries and accounts for factors such as grammatical genders and plurals.  

This feature was especially important to Deutsche Bahn, with Tom Winter, Data Scientist & Computational Linguist at DB, saying: 

“The ability to adapt the engine to DB’s corporate language via glossaries is a main advantage of DeepL compared to other machine translation systems. The correct use of our corporate language is very important for consistent communication throughout the whole Group. And with DeepL, it can be done very easily as long as you have a well-organized terminology database.” 

DB has been a satisfied DeepL customer since early 2022 thanks to its best-in-class translation quality, excellent data security, and customizability via its glossary feature.  

Going forward, DB is exploring even more instances where machine translation may be able to assist with its railway operations—such as communications with border traffic.

Weglot x DeepL: enhancing localization offerings with the highest-quality AI translation

Weglot is a Paris-based SaaS company that provides localization and translation services to clients around the world. With demand for its localization services high, Weglot needed translation APIs of exceptional quality—which made a partnership with DeepL the ideal choice. 

As an early adopter of DeepL API, Weglot and its customers have benefited from our accurate, high-quality AI translations since 2018—having already helped over 50,000 companies build multilingual websites. 

So, why DeepL? Weglot’s founder and CTO, Rémy Berda, was on the lookout for top-quality language translation APIs to enhance his company’s offerings and services. When customers started asking, “Have you added DeepL?” shortly after our DeepL API release, Berda’s interest was sparked. 

Chosen for its ease of use for developers and high-quality translations, over the last six years, DeepL API has helped Weglot translate billions of characters a month for companies all over the world. 

Thanks to the accuracy of DeepL’s AI translations, Weglot’s customers save time during their localization processes, which led them to work more efficiently.  

Since integrating the API, Weglot received plenty of positive customer feedback thanks to DeepL’s speed and accuracy. In fact, Berda himself recommended DeepL to developers who are looking for a high-performing product that’s true to its word, stating: 

“The documentation is clear, and the API does what it says it does. If you’re a developer, you only need to read the documentation, and the API will do exactly what you want.” 

As the e-commerce industry becomes more international, it’s crucial that companies of all sizes have access to high-quality localization and translation services. Thanks to translation tools offered by DeepL and Weglot, quick, accurate multilingual communication with customers and markets around the globe is not only possible–it’s easy.

Alza x DeepL: saving on localization operating costs with AI translation at scale 

illustration of three websites showing the localization process and machine translation

Known as the “Czech Amazon”, Alza is an e-commerce giant with key markets all over Europe—from Czechia to Germany to Hungary. Since its founding in 1994, Alza has grown from an online electronics shop to a complete marketplace, now offering laptops, video games, pet supplies, cosmetics, and more. 

In mid-2021, Alza noticed that DeepL added 13 new supported languages, with Czech, Slovak, and Hungarian being the most applicable. After some quality testing, Alza discovered DeepL to be a superior product to their current translation API and quickly made the switch.  

Since then, Alza has been using DeepL to localize its website into five different European languages: 

  • English 
  • Slovak 
  • Hungarian 
  • German 
  • French 

With over 3,000 employees, Alza is growing rapidly—at 20% annually—and recently expanded to Central Europe and the UK. To thrive in these new markets, Alza needed access to high quality translations that wouldn’t overburden its localization team with manual corrections.  

Thanks to DeepL’s superior translation quality, Alza saved thousands of euros per month in operating costs, as the brand’s human proofreaders spent significantly less time correcting DeepL translations—and could focus on higher-impact projects. 

Additionally, the migration from Alza’s previous translation API to DeepL took less than one week, and the effect was immediate. 

In the words of Jakub Kalina, head of Alza’s localization team: 

“When DeepL began supporting Czech and other key languages, we were quite surprised with the difference in quality. It sounded much more natural, so we decided it was worth making the switch.” 

Specifically, Alza used DeepL to translate large volumes of reviews, which provided quality assurance for potential customers. Having translated thousands of reviews from Czech into German and Hungarian, Alza saw a significant increase in its conversion rate. 

As for what’s next, Jakub also foresees a high-volume future for his team: 

“Thanks to a significant cost reduction and freeing up our translators’ time, we can now take on new translation projects, so it looks like our translation volume will continue to grow—it could even double or triple in the coming months.”  

Check out our Alza case study to learn more about how the Czech e-commerce giant uses DeepL to grow.

Improve your localization process with DeepL’s AI translation 

Clearly, DeepL’s high-quality, accurate AI translations are a contributing factor to these three companies’ successful localization processes.

Improve your company’s productivity, speed, and ROI with AI-powered document translation

What you need to know about AI-powered document translation: 

  • Machine translation plays a pivotal role in global business expansion, improving efficiency and streamlining multilingual communication

  • Businesses should embrace AI translation technology to navigate the complexities of multilingual communication and get ahead 

In a rapidly expanding global economy, effective cross-cultural communication has become more important than ever. For many organizations, a document that used to exist in a singular language now has multilingual requirements. Not fulfilling these requirements has consequences—namely, slower global growth, lower customer satisfaction, and decreased reach. 

However, thanks to the increasing use of AI-powered translation software, companies are meeting these challenges head on and experiencing a new era of productivity, speed, and efficiency for document translation. 

In this post, we’ll discuss the integral role of machine translation in global business expansion. Then, we’ll explain why AI translation tools like DeepL are the go-to solution for global companies looking to boost efficiency, enhance customer satisfaction, and improve return on investment (ROI). 

How important is machine translation to global expansion? 

For businesses, the benefits of machine translation are far-reaching. Organizations across countless industries are recognizing the important role machine translation plays in everything from internal communications to localization strategies to document translation.  

With automotive, healthcare, IT, and legal industries leading the way, AI-powered translation tools are spearheading international growth. According to a recent market forecast from Acumen Research and Consulting, machine translation will see a steady increase in use over the next eight years, with a key driver being new demand for multilingual communication.  

From technical information to customer communications, AI is reshaping the translation landscape. In fact, the European Language Industry Survey 2022 found that more than 70% of independent language professionals in Europe report using machine translation to some extent, demonstrating the technology's expanding footprint.  

Clearly, machine translation plays a vital role in organizations’ global expansion plans. But what are companies looking for when choosing an AI translation solution? Let’s discuss. 

What matters most for AI translation tools? 

When searching for a solution to their document translation needs, quality remains a critical factor for companies. In this regard, highly-trained AI shines.  

According to a recent survey from Unbabel, 83% of marketers using machine translation in their localization strategies expressed confidence in the quality of the translations. Furthermore, the highest quality translations were found in content with heavy documentation and technical terms—especially in sectors such as computer software, legal services, and telecommunications.  

This indicates that AI-powered solutions like DeepL possess real potential to improve translation accuracy and speed in these, and other, industries. This, in turn, will allow international companies to grow and expand more efficiently. 

Which document translation capabilities are the most important?

Here, DeepL excels by providing an easy-to-use, real-time online document translator. With DeepL Pro, you can transform your PDFs, Word Docs, PPTs, and more into 30+ languages with a single click—all while preserving their original format. 

Next, there’s accuracy and security. Be it internal reports, legal contracts, user manuals, or any other business document, DeepL’s AI-powered translation is an accurate, high-quality solution that prioritizes data security

With state-of-the-art transport layer security (TLS) encrypted data transmissions and a completely in-house PDF translation process, you and your team can rest assured that your translated documents are both accurate and secure.  

DeepL’s document translation feature helps foster meaningful communication between colleagues, teams, and offices, regardless of their language skills. And with the ability to translate documents at scale with DeepL Pro, you can ensure everyone is on the same page. 

How can AI document translation improve ROI? 

Return on investment can be a tricky metric to track with 100% accuracy. However, it’s still an important calculation to take into account when evaluating the relative efficacy and success of different projects.  

Here, AI translation solutions can improve companies’ ROI—not only in terms of cost, but also in terms of time.  

Whether you need to translate a document from German to English or French to Japanese, an AI translation tool’s ability to perform real-time translations is a game changer. Often, it eliminates the need for multiple revisions and ensures that companies can communicate effectively cross-culturally. 

In the race to expand globally, companies can and should rely on AI tools to translate large volumes of text and complex documents—making the process efficient and less daunting. So, which companies are already using DeepL to go global? We’ll cover that next.
