Fraud Experts Launch Silver Tail Systems to Lead the Fight Against Business Logic Abuse

PALO ALTO, CA, Apr 20 (MARKET WIRE) --
Silver Tail Systems, Inc. announced it raised over $2M in Series A
financing to lead the fight against business logic abuse. Silver Tail
Systems was founded in January, 2008, by Laura Mather, Ph.D. and Mike
Eynon, two fraud prevention experts who built anti-fraud and anti-phishing
tools at eBay and PayPal.

Today's sophisticated hacker now targets the legitimate business logic of
websites to perpetrate their fraud, including hijack threats, velocity
attacks and gaming schemes. Through Eynon and Mather's experience and
proprietary algorithms, they have developed software applications to
combat online fraud using new techniques which detect, investigate and
disrupt online fraud -- unlike anything in use today. "We formed Silver
Tail to build the most advanced solution possible in fighting online
fraud," said Mather. "We built the tools we always wished we had."

Co-Founder and CTO of WhiteHat Security and industry veteran Jeremiah
Grossman states: "Business logic abuse on publicly-facing websites has
resulted in five, six and seven figure losses at many brand-name Fortune
500 companies. It's great to see Silver Tail out there to detect and
prevent against this rising threat. WhiteHat Security sees these risks to
legitimate websites increasing significantly in 2009.

Silver Tail's Series A round was closed in September, 2008 and led by
Leapfrog Ventures, along with Seraph Group, Startup Capital Ventures and
individual investors. Capital raised during this funding enhances the
Silver Tail products and helps build out the company.
