NASDAQ-listed Ixia, which offers IP and wireless network testing and visibility solutions, has agreed to buy security testing company BreakingPoint Systems for roughly $160 million in cash.

Founded in 2005, BreakingPoint had raised at least $28 million in funding from firms like Austin Ventures and Genesis Inventions.

In May 2012, Ixia picked up networking monitoring gear and software company Anue Systems for $145 million in cash.

The purchase of BreakingPoint is anticipated to close in the third quarter of 2012, and is subject to customary closing conditions and regulatory approvals.

Ixia says the deal enables it to provide an end-to-end solution that monitors, tests, and optimizes converged networks and data centers.

BreakingPoint’s solutions provide visibility into emerging threats and applications, along with advance insight into the resiliency of an organization’s IT infrastructure under operationally relevant conditions and malicious attacks.

Its customers include enterprise companies like Yahoo and Korea Telecom, service providers and government agencies.

BreakingPoint booked revenue of $33.5 million in calendar year 2011. For calendar 2012, Ixia expects BreakingPoint’s revenue to grow by more than 40 percent.

Ixia itself expects $87 million to $89 million in revenue for its core business for the second quarter of 2012.
