When Renaming the File Is Not Enough
Protocol-level policies stop channels — content-aware blocking stops the data itself, regardless of which channel it travels through.
Most data leaks are not accidental in the way people assume. An employee knows the document is confidential. They attempt to forward it through a personal email account, drop it into a cloud drive, or copy it to a USB stick before resigning. Protocol-level policies stop some of those routes. They do not stop an employee who renames the file, changes the extension, or routes the content through an unfamiliar channel.
Content-aware blocking addresses a different layer: the content itself. Anexet analyzes what is being transferred — not just the filename or the protocol — against a library of analysis objects you define: digital fingerprints of sensitive source documents, cryptographic hashes of known files, sensitivity labels applied to classified categories, and thesaurus term sets covering industry- or company-specific vocabulary. A transfer attempt that matches any of these objects is blocked at the moment of interception, before the data leaves the endpoint.
The result is a policy that travels with the information rather than with the channel. Change the filename, switch to a different messenger, use an encrypted cloud service — if the underlying content still matches, the block still fires. In the Client Console, the security officer sees the blocked event: the user, the channel, the matched object, the timestamp. The document itself is preserved as evidence. Nothing was lost; nothing was sent.
