EMC to acquire Silver Tail Systems; security through big data

The data storage giant wants privately-held Silver Tail for its web fraud expertise.


Data storage giant EMC announced this morning that it will acquire privately-held Silver Tail Systems, a software security firm known for its real-time web session intelligence and behavioral analysis.

Terms of the deal were not disclosed.

Silver Tail will be rolled up into EMC's RSA enterprise security division, where it's expected to complement its identity protection and verifications software with fraud detection and behavioral analysis technology. Added value, in a nutshell.

For enterprises, security breaches are no longer a matter of "if" but "when." For financial institutions, online retailers and government websites, that could lead to attacks, account takeover and fraud. Spotting rotten transactions, then, is key. 

Silver Tail uses a Big Data-powered, web-based approach that it says gives it more scale to identify malicious behavior sooner. Big Data is all about finding patterns at scale; applied to cybersecurity, it means that anomalies can be identified and rooted out across an entire system, dynamically. Silver Tail plays at the large end of the spectrum, where its customers need to track more than 300,000 clicks per second.

The acquisition is expected to be completed in the fourth quarter of 2012.
