The company also offers AlienVault Unified Security Management or “AV-USM”, a commercial offering based on the OSSIM open-source project.

“Having been involved in the SIEM market since its inception, I have a deep appreciation for the new and exciting direction AlienVault is taking the technology and the market,” said Ted Schlein, Managing Partner, Kleiner Perkins Caufield & Byers. “Their open and collaborative Unified Security Management platform provides the kind of security visibility that no one has been able to deliver on yet. I’m very glad to be partnering with such a seasoned and successful team of executives to help evolve the security and SIEM markets.”

“Having worked with much of the AlienVault executive team when they were with Fortify, I trust in their ability to realize both the technology and market potential that their solutions represent. Their unique approach to security is something the market is hungry for, and I truly believe that with this team at the helm, AlienVault has the opportunity to redefine how security is done.” – Bob Spinner, Managing Director, Sigma.

KPCB Managing Partner Ted Schlein, who has also invested in companies such as Fortify Software (acquired by HP), ArcSight (acquired by HP), ISS (acquired by IBM), Mandiant, and Shape Security, will join AlienVault’s board of directors. Sigma Managing Director Bob Spinner, will participate as a “board observer”.
