Secure Mission Solutions (SMS) has acquired Sim-G Technologies, expanding its capabilities in physical and cyber security to support an integrated security focus.

Terms of the deal, which closed in December, were not disclosed. Sim-G, which is based in Northern Virginia, has more than 130 engineers and technical professionals working on cyber security, systems engineering and command and control support primarily for defense and intelligence community customers.

Sim-G will become an operating company of SMS, which also has a subsidiary WareOnEarth Communications. SMS is also based in Northern Virginia. Sim-G’s management remains intact.

“With the addition of Sim-G, SMS now has more extensive physical and cyber security capabilities to support its integrated security focus,” Tom Sundling, CEO of SMS, said in a statement.

The acquisition was financed by Riordan, Lewis and Haden Equity Partners, the principal investor in SMS. The investment banking firm SC&H Capital served as Sim-G’s financial adviser on the deal.
