Symantec Corp. will kick off its annual Symantec Vision conference next week with the first public release of its next-generation corporate antivirus software, called Symantec Endpoint Protection 11.0. The new software is a major advance for Symantec, which has been working for more than a year to integrate firewall, zero-day protection and network access control features into its antivirus product. Hamlet includes code from two recent Symantec acquisitions: It will include firewall capabilities based on the Sygate Enterprise Protection software Symantec acquired in 2005. Another new feature will be SONAR, (Symantec Online Network for Advanced Response), based on code that Symantec acquired as part of its 2005 purchase of Whole Security.
