Sentry EDS Overview

TechnologySentry EDS utilizes CYREN’s GlobalView™ Cloud data as one of the filtering layers. CYREN’s GlobalView™ Cloud is fueled by patented Recurrent Pattern Detection technology to deliver Web Security, Email Security, and AntiMalware solutions with uncompromising protection in both embedded and security-as-a-service deployment models.

Recurrent Pattern Detection (RPD)

TechnologyRPD, based on CYREN’s U.S. patent #6,330,590, extracts and then analyzes relevant message patterns, which are used to identify email-borne outbreaks. RPD classifies both distribution patterns and structure patterns and the analysis results are stored in a vast database of classifications. Local instances of RPD are used in the GlobalView Cloud to accurately detect low volume or regional Outbound Spam in conjunction with CYREN’s Outbound Anti-Spam solution.

Zero-Hour Outbreaks Protection

CYREN Virus Outbreak Detection (VOD) provides a complementary shield to conventional AV technology, providing protection in the earliest moments of malware outbreaks, continuing as each new variant emerges.
