Specialising in both commercial and federal government sectors, the acquisition enhances Security 101's foothold in the Mid-Atlantic region, marking its 19th strategic acquisition.

Now, with the acquisition, Robert Donnelly, a longstanding member of the leadership, assumes the role of General Manager, overseeing the operations within the Washington, D.C. area. "We’re excited to welcome SETEC to the Security 101 family," remarked Greg Daly, CEO of Security 101.

"Their strong reputation, technical expertise, and customer relationships in the D.C. corridor align perfectly with our growth strategy and strengthen our ability to serve the federal market."
