(Nasdaq: SNWL), a leading secure network infrastructure company, today announced the availability of a significant upgrade to its advanced enterprise-class email security solutions with the release of Email Security 7.2. As security threats based on email continue to increase in complexity, sophistication and volume, businesses both large and small remain at risk to spam and virus attacks capable of crippling the corporate network and greatly reducing productivity and network performance. SonicWALL's Email Security 7.2 delivers uniquely innovative email security features that are redefining the limits of security and scalability to ensure protection against these malicious and emerging threats.

Aimed towards both large enterprises and SMBs, SonicWALL's Email Security (SES) solutions are high-performance, easy to use, highly scalable and cost effective. This latest release for the SES product family delivers significantly enhanced levels of performance, effectiveness, ease of use and manageability for the entire breadth of the product line. Most notably, with the release of Email Security 7.2, SonicWALL's Advanced Reputation Management now provides effective protection against a wide variety email-borne spam and malware, including spam originating from "spambots".

According to SonicWALL's SonicLabs Threat Research team, spambots are now responsible for up to 90 percent of all spam. Spambots are automated computer programs used by "botnets", or armies of compromised computer systems ("zombies"), under a common control structure. SonicWALL is seeing massive proliferation of botnets and zombies, as spammers increasingly focus on developing techniques to avoid traditional IP reputation systems by compromising mail servers at legitimate companies and cracking webmail accounts.

As part of SonicWALL's patented multi-engine email security system, Advanced Reputation Management offers industry-leading protection against spambots, taking traditional IP reputation systems a step further by correlating and analyzing billions of data points from SonicWALL's GRID Network of email, Web and network security solutions in real time.

"SonicWALL continues to develop industry-leading email security technologies in the name of providing customers large and small with innovative, enterprise-class protection," said Edward Cohen, Vice President, Email Security Business Unit, SonicWALL.
