EMC has signed an agreement to acquire California-based Silver Tail Systems.

Silver Tail Systems, a web fraud detection and security software provider, is to be incorporated into EMC's RSA security division at the close of the deal, expected to be the end of the year.

EMC said it will enhance both RSA's identity protection and verification solutions and its enterprise security portfolio.

"Customers need better intelligence, analytics and the ability to respond in real-time, which is a capability that Silver Tail's products do extraordinarily well to help foil web-based attacks,” said Art Coviello, RSA executive chairman. “Silver Tail offers proven anti-fraud solutions that complement RSA's portfolio of risk-based and adaptive products and services.”

According to EMC, Silver Tail's products will add a disruptive fraud fighting and its core transaction and behavioural analysis technologies to RSA's enterprise security solutions.

“Silver Tail pioneered an approach that uses web session intelligence to provide unmatched visibility and the behavioural analysis that detects these threats and protects web-based platforms around the world. Together with RSA, we have an incredible opportunity to extend these capabilities beyond what we do today to protect web-based platforms,” Tim Eades, CEO at Silver Tail Systems, said.
