Objective

Highlight the outcome that Netskope does not re-examine files with the same MD5 hash permanently.

Prerequisite

This issue generally applies to all Netskope Standard and Professional DLP modules, including, but not limited to, NGSWG DLP, Email DLP, Endpoint DLP, and more.

Context

Customers can initially upload a file that contains no detectable data identifiers. Later, they may modify only the file name to include sensitive keywords. As a result, they can bypass Netskope’s DLP detection mechanism, potentially leaking sensitive information through the file name alone.

Do You Know?

If the administrator has not changed the DLP policies that should have been triggered, such data leakage will not generate any forensic records or DLP violation alerts. This means the administrator will be unable to track or investigate the data leakage incident.

Notes

We’ve discovered that others have already raised similar concerns. I encourage you to vote for this feature as well, as this design issue deserves Netskope’s immediate attention and should be addressed with an urgent fix.
