Mail Sentinel® Anti-Virus
feature is your first line of defense against virus
attacks. Activating the Mail Sentinel Anti-Virus option through GTA firewall's
email proxy for SMTP email means real-time scanning for viruses and other
malware is done at the perimeter before they reach your network. By employing
highly effective and respected open source virus definition lists, Mail Sentinel
Anti-Virus users receive the most complete and inclusive virus and malware
protection available.
When using Mail Sentinel Anti-Virus, each email message is quickly scanned and
its contents reviewed against a growing database of over 200,000 open source and
proprietary virus definitions that includes malware definitions for classic
viruses, network worms, trojan programs, DoS and hacking tools, flooders and
virus writing tools. Even unknown viruses are detected and prevented using
proactive virus detection mechanisms, providing sought after zero-day
protection. If a virus is detected, Mail Sentinel Anti-Virus will disinfect the
contents when possible.
The Mail Sentinel Anti-Virus feature provides flexible implementation to match
network bandwidth and corporate security policies. Network administrators can
customize how emails are handled with choices to accept, reject, tag or
quarantine emails with known viruses. Email containing viruses can be tagged for
easy recognition by the end users, who can then choose to filter tagged messages
using email rules. To optimize performance, email and attachment size limits can
also be established.
Mail Sentinel Anti-Virus automatically receives periodic updates of virus
definitions to ensure effective and accurate virus protection. As new virus
definitions are discovered, your GTA Firewall UTM Appliance is updated to
provide the best possible protection against email based virus attacks.
