KVKK · Personal data masking
Mask personal data in documents before you share them.
Redakt On-Premise finds and masks personal data such as names, Turkish ID numbers, IBANs, phone numbers and email addresses in Word, Excel, PDF and image files. It runs on your own infrastructure without sending documents outside your organization.

KVKK and document sharing
Share documents with only the personal data you need.
Documents shared with auditors, consultants or AI tools do not always need to include identity and contact details. Redakt helps you mask personal data that does not need to be shared.
-
External sharing
Mask personal data in contracts, reports and correspondence before sharing them with auditors, consultants or business partners.
-
AI tools
Mask documents before uploading them to an AI tool. Use Redakt Guard alongside Redakt On-Premise for automatic masking in your browser.
-
Analytics and test data
Mask personal data in employee and customer lists before using them for reporting, analysis or software testing.
“Being relevant, limited and proportionate to the purposes for which they are processed.”Turkish Personal Data Protection Law No. 6698 (KVKK), Article 4 · General principles
What it masks
Identify personal data in Turkish documents.
Validation algorithms check data such as Turkish ID numbers and IBANs. Local language models identify names of people and organizations, while your own rules identify company-specific terms.

Word and Excel files retain their original file format. Optical character recognition (OCR) runs on your device to read text from scanned pages.
Turkish ID numbers, IBANs and card numbers are verified with checksum algorithms. Context-dependent findings, such as names of people and organizations, are reviewed by the user before masking. Names of people, organizations and locations are recognized in Turkish and 10 other languages. OCR for scanned documents supports Turkish and English only.
How it works
Ready to share in three steps.
Choose a document
Drag and drop a file into the browser app. It is processed on your device and never uploaded to the server.
Review the findings
Review the detected data and deselect any items you do not want to mask.
Get the masked copy
Each selected value is replaced consistently throughout the document. For example, a person’s name becomes
[Person_1]and an IBAN becomes[IBAN_1]. The placeholders shown are the labels used by Redakt. Your original file is never modified.
Data security
Your data stays in your organization.
Redakt On-Premise runs on your own infrastructure without sending data to external services.
On-premises installation
Redakt runs on Windows Server with IIS and SQL Server. The server does not need internet access for installation.
No data sent to external services
Language models and OCR run locally. Document content is never sent to Siskon or any cloud service.
Document content is not logged
Logs never contain document content, file names or detected values.
You control access
Users sign in with Windows authentication. Your organization’s masking rules are stored in its SQL Server database.
Redakt Guard for AI tools
Redakt Guard masks files and text on your device before they are sent to AI services in Chrome or Edge. It is a separate product from Redakt On-Premise and works on its own.
