More than 500,000 professionals worldwide use DeepL Pro to ensure the confidentiality and security of their data.
We protect your data with the highest security measures
Data encryption
All data transferred between DeepL Pro subscribers and DeepL infrastructure is encrypted using state-of-the-art TLS encryption. We regularly review the cipher suites used and deprecate those which may become insecure in the future.
Data storage
DeepL Pro subscribers’ texts aren’t saved on persistent storage, but only stored in RAM. Translations of document files are only saved on disk temporarily for the execution of the translation. In this case, they are encrypted using state-of-the-art symmetrical encryption, with the key only stored in volatile memory and on the subscriber’s system. DeepL Pro subscribers’ texts are not used to train our models. Additionally, DeepL Pro subscribers’ glossary entries are saved in persistent storage to guarantee cross-platform ubiquity, whereas free users’ entries are only stored in the browser’s local storage.
Data centers
DeepL Pro servers are property of DeepL SE and operated in a co-location model in data centers in Finland with an ISO 27001 certified data center operator, which is audited by DeepL regularly. Our servers are protected by the highest physical means and only selected DeepL employees with operational tasks have access to them.
Reliability
All DeepL Pro networks are redundant and secured by automatic failover mechanisms to ensure trouble-free service, with a measured uptime of 99.92% in the last 12 months.
Subcontractors
DeepL avoids involving subcontractors as much as possible. When necessary, we carefully select them and, according to ISO 27001, audit all critical ones.
