Email.

New Feature: Outbreak Filters
AsyncOS 7.5 updates the Virus Outbreak Filters feature, now Outbreak Filters, to
protect your users from the growing trend of low-volume, targeted email attacks
in addition to virus outbreaks. The messages used for these threats, such as
phishing messages, scams, and malware distribution, are complex, evolving, and
can be more difficult to detect than widespread spam, phishing, and virus
outbreaks. The enhancements in the Outbreak Filters feature offer your users
protection from these attacks and prevents them from downloading malware or
distributing sensitive information. The Outbreak Filters feature can rewrite URLs
in messages to protect recipients from browsing to malicious websites and add
disclaimers to suspect messages to warn recipients.
