BOSTON -- IT security and control firm Sophos today announced the addition of Sophos eXtensible Lists (SXL) to its Email Security and Control solutions portfolio. SXL is an online look-up system that dramatically accelerates the distribution of anti-spam intelligence, moving away from traditional scheduled updates to a real-time system that provides quicker response to new and emerging spam campaigns. Sophos customers will receive this industry leading, rapid detection and deployment capability automatically.
Rather than requiring the anti-spam engine to rely solely on local data when checking messages for spam, SXL enables real-time access to a wider range of information. It contains current and historical anti-spam intelligence such as IP addresses, URIs, message checksums, image/document fingerprints, etc. If the local anti-spam engine cannot conclusively determine if a message is spam, it can now reference the SXL database (using the DNS protocol) to check for any additional information that might be available from SophosLabs, but not yet downloaded.
A hosted database service, SXL works in conjunction with Sophoss email gateway solutions Sophos Email Appliances and PureMessage for Exchange and UNIX to provide the most effective security and control available today.
