Which two features are applied to either incoming or outgoing mail policies?

Outbreak filters and antivirus are two features that can be applied to either incoming or outgoing mail policies on Cisco ESA. Outbreak filters allow Cisco ESA to detect and block messages that contain new or emerging email threats, such as viruses, worms, phishing, or spam, by using real-time updates from Talos intelligence. Antivirus allows Cisco ESA to scan messages for known viruses and malware using one or two antivirus engines (Sophos and McAfee).
