Silver Tail Systems.

Silver Tail was founded by a team of fraud prevention experts who built anti-fraud and anti-phishing tools at eBay and PayPal. Through their experience and proprietary algorithms, they have built a system that is scalable, minimizes false positive rates, and is extremely flexible to adapt to changing attack vectors. Silver Tail's recent work with several popular websites has found that as much as 50% of traffic can be robotic with a substantial amount of live exploits at any point in time. Most of this had been completely undetected by the sites. Silver Tail Forensics took minutes to discover the exploits, saving these companies weeks of analysis. Silver Tail Mitigation helps to divert and block the bad behavior in real time, saving the cost of resources to rewrite pages.
