DDoS Protection is a cloud based DDoS technology service that since its inception in 2007, has developed, implemented and real world tested a wide range of proprietarymethods and techniques to stop DDoS attacks. We do not rely on purpose built DDoS mitigation devices to stop all attacks. Our experience has taught us that no singleDDoS mitigation device can stop all varieties of DDoS attacks in existence today.

Denial-of-service (DoS) attacks are happening now and have evolved into complex security challenges for organizations large and small. Although DoS attacks are not a new phenomenon, the methods and resources available to conduct and mask such attacks have dramatically evolved to include distributed (DDoS) and, more recently, distributed reflector (DRDoS) attacks—attacks that simply cannot be addressed by traditional on-premise solutions.
