Every day, new viruses are released that have destructive consequences for businesses worldwide. Some have the ability to spread within hours & affect computers & networks of all sizes. Viruses, worms, Trojans & spyware programs cause serious financial damage to companies through data deletion, loss of productivity, network computer downtime, IT administrative overhead & bandwidth consumption. As these attacks become more dynamic & malicious in nature, businesses are forced to look past client-based protection & stop viruses before they have a chance to inflict damage. Sonic WALL has responded to these threats by developing scalable, high-speed gateway anti-virus, anti-spyware & intrusion prevention for its unlimited node TZ 170 Series security gateways. Sonic WALL Gateway Anti-Virus, Anti-Spyware & Intrusion Prevention Service delivers intelligent, real-time network security protection against viruses, spyware, worms, Trojans & application exploits. Utilizing a configurable, high-performance deep packet inspection architecture, Sonic WALL Gateway Anti-Virus, Anti-Spyware & Intrusion Prevention Service secures the network from the core to the perimeter against a comprehensive array of dynamic threats including viruses, spyware, worms, Trojans & software vulnerabilities such as buffer overflows, as well as peer-to-peer & instant messenger applications, backdoor exploits, & other malicious code. This unique solution features a high-performance deep packet inspection engine that delivers threat protection directly on the security gateway by matching downloaded, e-mailed & compressed files against an extensive signature database. Because new threats emerge daily & are often unpredictable, the signature database is constantly updated to deliver the highest protection possible against an ever-changing threat landscape. New signatures are created & added to the database by a combination of Sonic WALLs Sonic Alert Team & third-party sources. As an added layer of security, Sonic WALL Gateway Anti-Virus, Anti-Spyware & Intrusion Prevention Service provides application layer attack protection not only against external threats, but also against those originating inside the network.
