API (self-hosted on AWS): Signatures database

The signatures database is the heart of attachmentAV API. It contains patterns or “signatures” of known malware. The Sophos® scan engine uses these signatures to identify and detect malware. Without a comprehensive and up-to-date signatures database, a malware scanning tool may be ineffective in detecting and protecting against new and emerging threats.

attachmentAV API updates the signature database during startup as well as approximately every 1 hour.

We also host a mirror of the Sophos® signature database that we sync approximately every hour to guarantee priority access to the signatures database for our customers.
