SonicWall’s gateway protection for the NSA 4650 combines anti-virus, anti-spyware and intrusion prevention into a single, high-performance service that blocks spyware installs at the gateway and severs covert communications from infected hosts. Its intrusion prevention scans packet payloads for worms, Trojans, buffer-overflow exploits, backdoors, P2P/IM threats and other application-layer attacks.
Built on a high-performance deep packet inspection engine that uses parallel searching algorithms up through the application layer, the service minimizes CPU/memory impact while maximizing throughput. A per-packet scanning architecture enables virtually unlimited file-size handling and supports hundreds of thousands of concurrent downloads for exceptional scalability.
Administrators gain granular application control to monitor, throttle or block instant messaging and peer-to-peer traffic—closing common backdoors, conserving bandwidth and improving productivity. Easy policy creation and centralized management simplify deployment across distributed networks while delivering robust, enterprise-grade protection at the gateway.
