SonicWALL Network Anti-Virus Overview
The widespread outbreaks of viruses illustrate the problematic nature of virus defense for small
offices. Users without the most current virus definition files allow these viruses to multiply and infect
many other users and networks. By their nature, anti-virus products typically require regular, active
maintenance on every PC. When a new virus is discovered, all anti-virus software deployed within an
organization must be updated with the latest virus definition files. Failure to do so severely limits the
effectiveness of anti-virus software and disrupts productive work time.
SonicWALL Network Anti-Virus is a SonicWALL subscription service that prevents occurrences like
these and offers a new approach to virus protection. The SonicWALL security appliance constantly
monitors the version of the virus definition file and automatically triggers download and installation of
new virus definition files to each user’s computer. In addition, the SonicWALL security appliance
restricts network users’ access to the Internet until they are protected, therefore acting as an enforcer
of the company’s virus protection policy. This new approach ensures the most current version of the
virus definition file is installed and active on each PC on the network, preventing a rogue user from
disabling the virus protection and potentially exposing the entire organization to an outbreak.
Note: Refer to the SonicWALL Network Anti-Virus Administrator’s Guide available at the SonicWALL
documentation Web site <http://www.sonicwall.com/services/documentation.html> for complete
configuration instructions.
