SonicWALL® Gateway Anti-Virus, Anti-Spyware and Intrusion Prevention Service integrates gateway anti-virus, anti-spyware and intrusion prevention to deliver intelligent, real-time network security protection against sophisticated application layer and content-based attacks. Because new threats emerge daily and are often unpredictable, SonicWALL is able to deliver the highest protection possible with a deep packet inspection engine that delivers threat protection directly on the security gateway by matching downloaded, e-mailed and compressed files against an extensive and continuously updated database of signatures written by a combination of SonicWALL's SonicAlert Team and third-party sources.
