GREENWICH, Conn., Aug. 27, 2019 /PRNewswire/ — Southfield Capital, a premier lower middle market private equity firm, announced today that Protos Security (“Protos”), a tech-enabled managed security services provider, has completed its strategic acquisition of Security Resources (“SRI” or the “Company”), a leading US-based managed security services and direct guard solutions provider.

“Over the last 20+ years, SRI has blossomed into one of the leading names in the security services space and they have built a highly respected business with a great client roster,” said Andy Cook, Partner at Southfield Capital. “We believe that combining SRI with Protos’ industry leading technology will enable us to deepen client relationships and provide a broader array of comprehensive security and loss prevention solutions.”
