SonicWALL Gateway Anti-Virus Overview
SonicWALL Gateway Anti-Virus is part of the SonicWALL Gateway Anti-Virus/Intrusion Prevention
Service solution that provides comprehensive protection against real-time for viruses, worms,
Trojans, and software vulnerabilities using deep packet inspection scanning engine. SonicWALL’s
unique solution features a high-performance deep packet inspection architecture that scans for
viruses on a packet-by-packet basis, rather than copy every packet into a file and then scanning the
file. SonicWALL Gateway Anti-Virus has the capacity to analyze files of any size and an unlimited
number of files per user, providing ultimate scalability.
When you activate SonicWALL Gateway Anti-Virus, SonicWALL Intrusion Prevention Service is also
activated to provide comprehensive, real-time gateway anti-virus and intrusion prevention. The
SonicWALL Gateway Anti-Virus/Intrusion Prevention Services secures your network from the
gateway against a comprehensive array of dynamic threats. No client software is required.
Note: Refer to the SonicWALL Intrusion Prevention Service 2.0 Administrator’s Guide for information
you need to successfully activate, configure, and administer SonicWALL Intrusion Prevention Service
2.0 on a SonicWALL security appliance.
SonicWALL Gateway Anti-Virus delivers threat protection directly on the SonicWALL security
appliance by matching downloaded or e-mailed files against an extensive and dynamically updated
database of high threat virus signatures. Virus attacks are caught and suppressed before they travel
to employee desktops. New signatures are created and added to the database by a combination of
SonicWALL’s SonicAlert Team, third-party virus analysts, open source developers and other sources.
SonicWALL Gateway Anti-Virus can be configured to protect against internal threats as well as those
originating outside the network. It operates over a multitude of protocols including SMTP, POP3,
IMAP, HTTP, FTP, NetBIOS, instant messaging and peer-to-peer applications and dozens of other
stream-based protocols, to provide administrators with comprehensive network threat prevention and
control. Because files containing malicious code and viruses can also be compressed and therefore
inaccessible to conventional anti-virus solutions, SonicWALL Gateway Anti-Virus integrates
advanced decompression technology that automatically decompresses and scans files on a per
packet basis.
