Clearlake Capital Group L.P. has reached a deal to purchase Landesk Software Inc., a network security provider for access endpoints, from Thoma Bravo LLC. The target will merge with the buyer’s portfolio company Heat Software, a cloud service management company, as part of the deal.

Network security providers are receiving a strong interest from strategic buyers and private equity firms alike, as high-profile breaches demonstrate the need for protection, including: denial-of-service attacks on Internet tech provider Dyn, currently being acquired by Oracle Corp. (NYSE: ORCL); the announcement that 500 million Yahoo accounts had been hacked in 2014 in the midst of the struggling Internet's planned acquisition by Verizon Communications Inc. (NYSE: VZ); and the cyber-intrusions into the computers of the Democratic National Committee and other Democratic Party groups. On Dec. 9, President Barack Obama ordered the intelligence community to conduct a "full review" of "malicious cyber activity" timed to U.S. elections.
