Belmont, CA based, Inc. is an early-stage stealth startup developing an improved, cloud-based defense system to prevent DDoS attacks from achieving their objective: shutting down the online sites of the world’s largest financial institutions, retail, government and internet sites. It may be better classified as modern day cyber terrorism. The company was founded in late 2012 through the cooperative efforts of Barrett Lyon, a serial entrepreneur and one of the leading experts in DDoS, and David Cowan, Partner at Bessemer Venture Partners (BVP) who co-founded VeriSign. is essentially a front-line defense against DDoS attacks and acts as a scrubbing center of incoming web traffic through a seamless integration where users cannot tell an attack is underway. Inbound user traffic is directed to’s servers where the traffic is analyzed and filtered using their proprietary algorithms, leaving only the legitimate traffic to be redirected to the customer’s servers. All outbound traffic is handled by the customer’s own web servers as opposed to responding through outside parties, providing the advantage of data protection. With Prolexic (the market leader’s solution), outbound traffic is rerouted through Prolexic’s servers which is technically against federal data policy regulations, but the financial institutions still do so because there is no other option. only works with inbound traffic, is always on, is customizable for load sharing, and uses IP Reflection to have all packets return from the BofA site.
