Frequently Asked Questions
Which password-protected file types are currently detected by Microsoft Purview DLP?
Currently, Microsoft Purview DLP natively detects and processes password-protected Microsoft Office documents, ZIP archives, and 7Z files for compliance policy matching.
Why does Microsoft DLP fail to scan certain encrypted file types?
Encrypted files conceal their internal text and data signatures from scanning engines. While DLP can read the headers of common formats like ZIP or Office to flag them as encrypted, it requires dedicated engineering to recognize the encryption wrappers of every distinct file format in the market.
Can I block all unsupported encrypted files as a failsafe in DLP?
Yes. You can configure a DLP rule using conditions such as 'Document is password protected' or 'File extension is' to proactively block or flag specific encrypted file types that prevent data inspection.
