How Witness handles your media and your data.
Last updated October 2026
How media is handled
Files and links are analysed and discarded. They are not stored, shared or used for training.
What we keep
The scan ID, the result, signal scores and timestamps, so a result can be referenced later without keeping the file.
Accounts and access
Work accounts add a team workspace. Single sign-on is available on Enterprise.
Deployment
Enterprise customers can discuss on-premise deployment, so the detectors run in your own cloud or servers.
Honest limits
A result is a likelihood, not a certainty. We show the signals behind it and say where confidence is lower.
Reporting a vulnerability
