Which feature of E-mail Security protects users from virus outbreaks using the Tabs database to quarantine suspicious messages?

Antivirus defense performs signature-based scanning against known malware definitions but does not use outbreak intelligence to quarantine messages during emerging, pre-signature outbreaks.

Outbreak Filters leverage Cisco Talos outbreak intelligence rules - referenced as the 'Tabs database' in the question - to identify and quarantine messages that match active outbreak patterns, providing protection during the window between outbreak emergence and signature release. This proactive quarantine approach is distinct from traditional signature-based scanning and is the specific feature designed for real-time outbreak response on the Cisco Email Security Appliance.

Data Loss Prevention inspects outbound email for sensitive content such as PII or financial data to prevent data exfiltration, which is unrelated to inbound virus outbreak detection.

Advanced Malware Protection provides deep file analysis and sandboxing for attachment-based threats but operates independently from the Outbreak Filters quarantine mechanism that uses Talos outbreak rules.
