OCS completes Top Security acquisition

OCS has acquired Top Security, a technology-led security company operating across Ireland.

The acquisition enhances OCS’s technology-enabled security capability, expanding its remote monitoring services, control room operations, communications resilience, and Alarm Receiving Centre (ARC) capabilities, alongside the facilities management and guarding services already delivered across Ireland.

Founded over 40 years ago, Top Security operates a nationwide monitoring network, including its own Alarm Receiving Centre and an independent radio communications network, delivering resilient monitoring capabilities for private and public-sector environments.

Integrating monitoring, technology, and frontline security services enhances OCS’s ability to deliver a more integrated security and Total Facilities Management model in Ireland. This combined capability supports a coordinated service across security, technology, and facilities management, supported by real-time monitoring and operational insights.

Daniel Dickson, Chief Executive Officer, UK & Ireland, OCS, said: “Top Security has built a strong reputation in the Irish market for its monitoring expertise and security technology capability. Bringing the business into OCS enhances our ability to deliver technology-enabled security services and integrated facilities management across Ireland.

“Customers increasingly require security, technology and facilities management to operate as a coordinated service. This investment expands our capability and supports safe, resilient environments for the organisations we work with.”

Emmet O’Rafferty, Chairman of Top Security Group commented: “Joining OCS marks an exciting new chapter for the business. We share a commitment to service quality and long-term customer partnerships. Being part of OCS offers a solid platform to further develop our monitoring capabilities while creating new opportunities for our customers and colleagues.”
