Virus Outbreak Filters
IronPort’s Virus Outbreak Filters feature provides you with a “head start” when
battling virus outbreaks. Historically, as new viruses or variants hit the Internet,
the most critical time period is the window of time between when the virus is
released and when the anti-virus vendors release an updated virus definition.
Having advanced notice — even a few hours — is vital to curbing the spread of
malicious code. During that vulnerability window, a modern virus can propagate
globally, bringing email infrastructure to a halt.

IronPort’s Virus Outbreak Filters act proactively to provide a critical first layer of
defense against new outbreaks. By detecting new outbreaks in real-time and
dynamically responding to prevent suspicious traffic from entering the network,
IronPort’s Virus Outbreak Filters offer protection until new anti-virus signature
updates are deployed. Integrated into IronPort’s email security appliances, the
Virus Outbreak Filters have two principal components: the outbreak detection
technology and the intelligent quarantine system implemented in the IronPort
appliances.

IronPort’s industry leading Virus Outbreak Filters technology provides “fire and
forget” functionality, requiring no administrator interaction once enabled. The
technology uses two different rule sets to provide the highest efficacy and the
most focused set of criteria for virus detection to ensure that filters can be laser
focused on a particular threat. The Virus Outbreak Filters rules and actions are
visible to the administrator, not hidden away behind the scenes, providing instant
access to the messages that were quarantined, and the reason why they were
quarantined.
