Sept. 29, 2008 - PRLog -- IntruGuard, The leading DDoS mitigation solution provider, announced that the U.S. Patent and Trademarks Office (PTO) has issued U.S. patent No. 7,426,634 to IntruGuard Devices, Inc. for a "METHOD AND APPARATUS FOR RATE BASED DENIAL OF SERVICE ATTACK DETECTION AND PREVENTION ". This patent granted by the U.S. PTO covers technologies that are key elements of Distributed Denial of Service (DDoS) attack mitigation.

-- SYN Flood detection and prevention mechanism,
-- Zombie flood detection and prevention mechanism,.

"Most other vendors have added incremental and incomplete DDoS mitigation features to existing firewalls and Intrusion Prevention Systems. We looked at the problem afresh and came up with path-breaking techniques which have been implemented in silicon. That makes us unique and that’s the reason these claims were granted. For last 3 years, many customers globally have used our products and validated our now patented techniques."
