Antispam vendors spread their wings

"During the past few years, enterprise e-mail security needs have expanded beyond simply fighting spam. As a result, vendors in this space are left having to continuously enhance their products with related features in order to keep up. These companies, including CipherTrust, Tumbleweed, MessageLabs, Espion, Symantec and many others, continue a steady march beyond what two years ago was the defining task in this market -- blocking spam. Today, enterprises need to protect themselves from more than just unwanted e-mail, and are looking to their messaging security providers for myriad functions including instant messaging and Web security, outbound e-mail encryption and policy enforcement, and extra measures to fight viruses."
