Protocol filtering

Antivirus protection for application protocols is provided by the ThreatSense scanning engine, which integrates multiple advanced malware scanning techniques. Protocol filtering works automatically, regardless of the Internet browser or email client used. If protocol filtering is enabled, ESET Mail Security will be checking communications that uses the SSL/TLS protocol, go to Web and email > SSL/TLS.

Enable application protocol content filtering - can be used to disable protocol filtering. Note that many ESET Mail Security components (Web access protection, Email protocols protection and Anti-Phishing) depend on this and will not function without it.

Excluded applications - allows you to exclude specific applications from protocol filtering. Click Edit to select them from the list of applications.

Excluded IP addresses - allows you to exclude specific remote addresses from protocol filtering.

Exclusions are useful when protocol filtering causes compatibility issues.
