Mandiant , the leader in advanced threat detection and response solutions and services, today announced that One Equity Partners (OEP), the private investment arm of JPMorgan Chase & Co., and Kleiner Perkins Caufield & Byers (KPCB) have completed a strategic investment in the company. Mandiant also announced the addition of Ted Schlein (KPCB) and A. Jody Gessow (OEP) to its Board of Directors.

“We look forward to scaling and meeting the significant demand for Mandiant products and services with the resources of KPCB and OEP,” said Mandiant CEO Kevin Mandia. “Ted and Jody bring decades of proven security and executive experience and we welcome them to the board.”

“Over recent months the importance of knowing whether your network has been breached has become alarmingly clear. Mandiant is the global leader in helping major corporate and government entities answer this question and execute an effective response. With the experience and financial resources of Mandiant’s new investors, we are confident Mandiant will prosper in the years ahead. We are delighted to become their partner in fulfilling their long-term goals,” said OEP’s Jody Gessow.

“The number and scope of advanced and targeted attacks continues to increase, and preventive measures alone are no longer sufficient to protect organizations from intrusions”, said KPCB’s Ted Schlein. “Mandiant is uniquely positioned to be the early warning system for the next wave of advanced attacks. I am excited to be part of the team that is doing so much to ensure organizations have an aggressive and successful security posture.”
