Postini Email Security
Postini Email Security is a comprehensive service to stop spam, viruses, phishing, denial-of-service and directory harvest attacks. Its multilayered protection includes heuristic and signature-based detection, and it provides detailed quarantine summary reporting to administrators through a Web console.
Delivered on the software-as-a-service model (SaaS), Postini Email Security doesn't require hardware or software, which reduces IT resource requirements and can relieve management headaches.
Postini says its patented architecture ensures no delays or disruptions to email service, no matter how high spam volumes reach. Google, in February, released messaging services that streamline Postini's assorted services into three basic bundles, for Lotus Notes, Microsoft Exchange and Novell GroupWise.
