EMC Corporation today announced an agreement to purchase Silver Tail Systems.

"Silver Tail does what is known as web session intelligence, drawing on various points of data, from the sessions themselves to what is happening across an enterprise, to determine where anomalies occur or there is a genuine threat to the business," writes TechWeekEurope's Tom Brewster.

"Before founding Silver Tail four years ago, Mike Eynon and Laura Mather worked for three years on the antifraud teams at eBay and PayPal, two of the most targeted sites on the Web," writes The New York Times' Nicole Perlroth. "From what they learned they started Silver Tail, which searches for online fraud in real time."

"The company's software detects malicious activity by monitoring and analyzing site visitors' behavior in order to determine whether it’s harmless or potentially harmful," writes GigaOM's Derrick Harris. "The company claims multiple large banking and e-commerce sites among its customers."

"The terms of the deal weren’t released, but it’s expected to close within the next three months," writes VentureBeat's Jolie O'Dell. "Silver Tail will become part of EMC's RSA security division (the product of a previous acquisition) and will augment the company’s Identity Protection and Verification (IPV) and other security products."

"The industry is well beyond the point of providing effective security using static, perimeter point tools that fail to keep up with dynamic cyber attackers," RSA executive chairman Art Coviello said in a statement. "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. Silver Tail offers proven anti-fraud solutions that complement RSA's portfolio of risk-based and adaptive products and services."
