Northrop Grumman [NOC] has reached an agreement to acquire M5 Network Security, an Australia-based provider of cybersecurity and secure mobile communications products and services.

Northrop Grumman said yesterday it expected the deal to close later this year pending a review by the Australian government. It did not disclose the financial terms of the arrangement with the privately held firm, but said the acquisition will not affect the company’s 2012 financial outlook.

“This acquisition enhances our ability to provide innovative, agile and proven cybersecurity and communication solutions to Australian customers,” Northrop Grumman CEO and President Wes Bush said.

M5 Network Security, headquartered in Canberra, provides services to the Australian military and intelligences services.

“M5 Network Security remains committed to maintaining the highest level of performance and service for our customers,” Matthew Wilson, the managing director of M5 Network Security, said. “We expect that as part of Northrop Grumman, our customers also will benefit from the cybersecurity leadership and extensive resources that Northrop Grumman can bring to M5 Network Security and its employees.”
