Data protection for every kind of document
Less manual work. Even more rigour.
Data Anonymizer finds the personal data and suggests a replacement for each item. Your team reviews it with everything highlighted, and always has the final say.

The video (2 min 10 s, no narration, with background music) shows the Data Anonymizer application at work: the user uploads documents to the workspace and can catalogue them; the tool processes them automatically; the user does the final check in the editor, saves and downloads the document; finally, the anonymised version is compared with the original in Word.
Built for people who anonymise every day.
More documents, same team
The people who already anonymise do the same work in far less time, with no extra staff.

What users say
Translated from Portuguese.
“With Data Anonymizer I can anonymise many more documents a day — and I feel less tired.”
“The platform is very intuitive, and whenever I have a question the support team sorts it out.”
“I can’t imagine going back to anonymising court decisions without it.”
Frequently asked questions
Is anonymisation 100% automatic?
The tool makes the suggestion; the user reviews and approves it. That combination is what ensures quality and accountability.
Which documents does it accept?
Word, PDF (including scanned files) and Excel: court decisions, minutes, legal opinions, contracts, administrative files and more.
Are documents kept?
Only for the agreed retention period; after that they are permanently deleted.
Can I try it with my own documents?
Yes. In the demo we use documents from your organisation, so you see the results in your real context.
