By Amit Chowdhry ● Apr 23, 2026

Protos Security announced it has acquired AT-RISK International, a globally recognized provider of executive protection, intelligence, and risk consulting services, marking a significant step in Protos’ strategy to build a software-enabled, integrated protection platform with global reach.

The acquisition enhances Protos’ capabilities across intelligence-led services, including risk consulting, investigations, threat assessments, and global risk monitoring. It also strengthens the company’s offering in executive, residential, event, and asset protection, positioning Protos to better serve enterprise and high-net-worth clients with increasingly complex security needs.

Protos said the deal advances its broader vision of delivering a differentiated, end-to-end protection platform that integrates physical security, technology, and intelligence services. The addition of AT-RISK International expands Protos’ footprint into higher-value advisory services while reinforcing its leadership in off-duty and specialized security offerings.

AT-RISK International will continue to operate under its existing brand, with its leadership team remaining in place to ensure continuity for clients and employees.

The transaction also aligns with Southfield Capital, Protos’ private equity partner, and its investment strategy, which has supported the company’s growth through targeted acquisitions aimed at scaling a comprehensive security services platform.
