Tripwire has announced its purchase of nCircle to add performance, auditing and vulnerability management solutions to its suite.

Jim Johnson, CEO of Tripwire, said: “Tripwire and nCircle have the opportunity to be a powerful and transformational combination in the rapidly changing security market. Our combined solutions are uniquely positioned to align security posture with business objectives, a crucial step in making security and risk meaningful and actionable across the enterprise.”

Tripwire, that was acquired by investment firm Thoma Bravo in 2011, will add nCircle's automated security and compliance auditing solutions to its compliance and event management range of products. The acquisition is expected to close in April and is subject to the customary closing conditions. The terms of the deal have not been disclosed.

Abe Kleinfeld, CEO of nCircle, said: “Security experts know that continuous monitoring — the process of finding and eliminating vulnerabilities before they can be exploited — is a foundational component of any security framework and the most cost effective way to reduce the risk of security breaches.

“The combination of Tripwire and nCircle brings together the industry's leading researchers and the broadest and deepest solutions for reducing risk.”

Charles Kolodgy, research vice president, security products at IDC, said: “It's difficult to mitigate attacks without understanding vulnerabilities and assessing that resources allocated to IT security are spent wisely. Organisations must also be able to maintain an optimal security posture. The combined solutions will enable Tripwire to advance the state of the art in risk-based security management.”
