Irving-based Summit Off Duty Services, a provider of off-duty police officer security, has been acquired by Connecticut-based Security Services Holdings LLC (Protos Security), a tech-enabled vendor managed security services provider in North America, Southfield Capital announced.

Summit President Alex Smith said that the shared mission with Protos of “providing high quality security solutions” made for a favorable partnership.

Summit’s suite of services and features provides access to more than 60,000 police officers, representing more than 1,400 law enforcement agencies.

“This acquisition greatly accelerates the growth of our organization and enhances our off-duty law enforcement service offering while also positioning us as the fourth largest security services provider nationally,” Protos CEO Mark Hjelle said in a statement.

Hjelle said that the combined companies would allow them to better serve clients across the nation with a large network of off-duty officers and “is a great investment.”

He added, “We couldn’t be prouder to have Summit in our portfolio.”
