Global market intelligence firm IDC has placed content security software provider Websense at the top of its IDC Worldwide Web Security Forecast for the fourth year in a row.

IDC says that Websense has "definitive market leadership," with a nearly 18-percent share of the Web security market, as well as the top share in Web security software and appliances.

Websense was able to nab the coveted #1 spot largely because IDC found that its TRITON platform had "mastered the integration of the three pillars of content security," made up of Web, email/messaging and data loss prevention.

TRITON provides users with unified Web, email and data security (either together or in individual options). The solution comes as an enterprise-ready appliance, cloud service and/or on-premise/cloud hybrid technology, while offering unified threat analysis and a management console with inbound and outbound controls.
