Mountain View, Calif. -- Shape Security, a Mountain View-based start-up developing new web security technology, said on Thursday it has raised $6 million in its first round of funding. Kleiner Perkins Caufield & Byers (KPCB) and Google chairman Eric Schmidt's TomorrowVentures co-led the round, which also included participation by Accel partner Peter Wagner, Baseline Ventures and executives from LinkedIn, Twitter and Facebook. Ted Schlein, general partner at KPCB, has joined the company's board of directors along with Gaurav Garg, a special limited partner at Sequoia Capital and personal investor in the round. "Shape's technology will shift the burden of attack from defenders to attackers," said CEO Derek Smith. "In doing so, Shape is aiming at the economics of web hacking and forcing attackers to spend more and more to achieve less and less."
