Our live anti-spam brings detection and protection even closer together. You'll get the latest spam campaign data from our experts as it's available, even before the next update downloads. If the locally stored spam data doesn't have all the information, our tools do a fast network check to the nearest Sophos Live Anti-spam server. This means as soon as we get new data (sender IPs, message and attachment fingerprints, destination URLs and checksums) every Sophos anti-spam engine can access it immediately while scanning a suspicious email.
