Sophos, a world leader in IT security and control, today announced that its email security appliance, ES4000, has been awarded West Coast Labs Checkmark for 100% detection of in-the-wild viruses.

The accolade confirms the hardware appliance's ability to detect 100% of the viruses found in the wild, and its position as one of the most powerful gateway protection products available.

"[The ES4000] security appliance is designed for corporate customers. It monitors incoming email messages for spam, viruses and other forms of malware and is more than capable of handling up to 80,000 messages per hour thanks to its high hardware specification," wrote West Coast Labs in their June 2007 technology report, 'Anti-Malware Solutions'.

West Coast Labs concluded "The ES4000's consistently reliable performance and high capacity make this well worthy of consideration by all corporate customers."

The West Coast Labs Checkmark certification for the ES4000 email security appliance follows news earlier this week that Sophos Anti-Virus had won its 38th VB100 award from Virus Bulletin magazine. The VB100 award is given to products found to detect 100% of the in-the-wild viruses, without suffering from a single false positive. In tests published in the June 2007 edition of Virus Bulletin, Sophos was found to have outperformed a number of competing products from other vendors.

"Sophos's managed security appliances help protect organizations against threats such as viruses, spyware and spam - and its important for us and our customers to have the quality of our protection tested by independent experts," said Graham Cluley, senior technology consultant for Sophos. "We're delighted to see Sophos achieve West Coast Labs Checkmark certification again, and are confident that Sophos offers not only the best in customer service and technical support, but also delivers a first class defense against malware attack."

All Sophos products use the same technology to protect against viruses, worms, spyware, Trojan horses and other malware, ensuring consistently high detection rates across all operating systems.
