Security Services Holdings (dba Protos Security), a tech-enabled managed services security guarding provider and portfolio company of Southfield Capital, has acquired ControlByNet.

ControlByNet provides remote guarding and software services that work across all devices through the cloud and onsite managed service. The deal expands Protos’ services offering and value delivered to its customer base.

“Over the last 20+ years, CBN has developed an impressive suite of technology offerings capable of servicing the remote guarding/security needs of clients across devices,” said Andy Cook, partner at Southfield Capital. “We believe that combining CBN with Protos’ industry leading technology platform will enable us to deepen client relationships and provide a broader array of comprehensive security solutions.”
