Sophos is expanding its email security and control solutions with the addition of real-time spam look-up system, claims to beat rival scheduled update models.

Sophos eXtensible Lists (SXL) aims to accelerate the distribution of anti-spam intelligence by providing real-time access to a wide range of information, including current and old anti-spam intelligence, in order to respond to spam attacks.

SXL works as a hosted database service with Sophos email gateway solutions, including Email Appliances and PureMessage for Exchange and UNIX, to check messages for spam. It accesses the SXL database for additional information that has not been downloaded from SophosLabs.

Sophos claims the SXL does not rely on more traditional scheduled updates and provides a quicker response to new and emerging spam attacks.

Jeff Epstein, a gateway security expert at Sophos, believes that spam techniques are becoming more complex and put a huge strain on corporate networks.

“Spammers and spam techniques continue to get smarter and in order to guarantee protection, detection methods must follow suit. With the addition of SXL, we’re offering our customers the faster, more comprehensive spam detection they require for effective spam prevention,” he said.

Sophos’s current email security customers will receive the SXL automatically.
