GTA's Anti-Virus feature is the first line of defense against virus attacks.
Activating the 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, Anti-Virus users receive
the most complete and inclusive virus and malware protection available.
When using the Anti-Virus feature, 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 by the Anti-Virus, the
contents will be disinfected when possible.
GTA's 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.
The Anti-Virus feature 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
