Protos Security Acquires AT-RISK, Forging an Intelligence-Led Global Platform

NORWALK, Conn. – April 21, 2026 – Protos Security, a prominent North American provider of technology-driven security services, today announced its acquisition of AT-RISK International, a globally recognized firm specializing in executive protection, intelligence, and risk consulting. The move marks a significant strategic pivot for Protos, accelerating its transformation from a managed services provider into a comprehensive, intelligence-led protective services platform with global capabilities.

The acquisition signals a broader trend within the security industry, where the demand for integrated solutions that combine physical presence with sophisticated intelligence and technology is rapidly outpacing traditional guarding models. This deal brings AT-RISK's deep expertise in high-stakes protective services under the umbrella of Protos' extensive software-enabled network.

A Strategic Shift Beyond Traditional Guarding

For years, the security sector has been defined by physical guards and patrol services. Protos Security built its reputation on modernizing this model, leveraging a proprietary software platform and a vast network of vetted security partners, including the largest off-duty law enforcement network in the nation, to manage complex security programs for multi-site organizations. However, today's announcement signifies a deliberate evolution beyond that core.

The addition of AT-RISK International introduces a new layer of high-value, advisory-led services. AT-RISK specializes in the nuanced world of threat assessments, global risk monitoring, investigations, and elite protective services for executives, high-net-worth individuals, and sensitive corporate assets. These are not services that can be simply scaled with more personnel; they require deep domain expertise and a proactive, intelligence-driven approach, which AT-RISK has cultivated since its founding in 2003.

"This acquisition marks an important milestone in our growth strategy," said Mark Hjelle, CEO of Protos Security, in a statement. "AT-RISK International adds specialized capabilities that expand our platform into high-growth areas. Together, we are better equipped to serve clients with complex, evolving security needs while expanding our addressable market."

The combination allows Protos to address a growing client demand for end-to-end security solutions. An enterprise client can now rely on a single partner for everything from uniformed guards at a distribution center to a global threat assessment for its traveling executive team, all managed through an integrated platform.

Consolidating a Fragmented Market

This acquisition is the latest and perhaps most transformative move in a calculated growth campaign orchestrated by Protos and its private equity backer, Southfield Capital. Since Southfield acquired Protos in 2019, it has pursued an aggressive "buy and build" strategy, completing ten acquisitions to consolidate a historically fragmented market. Past acquisitions have included Security Resources, Mulligan Security, and Summit Off Duty Services, each adding scale and specific capabilities to the platform.

Southfield Capital’s commitment to this strategy is underscored by its creation of a $179 million Annex Fund in 2022 specifically to finance Protos' M&A activities. This dedicated capital allows Protos to act decisively on strategic opportunities like the AT-RISK deal.

The financial logic is clear: move upmarket into more profitable service lines. "AT-RISK enhances both the quality and mix of our revenue by expanding into premium, advisory-led services," noted Anthony Escamilla, CFO of Protos Security. "This transaction supports our long-term growth strategy, strengthens our ability to scale while expanding our capabilities and further differentiating our platform in a fragmented market."

This disciplined approach has been validated by Protos' rapid growth and is a cornerstone of its private equity ownership's vision. "Protos continues to execute on its disciplined acquisition strategy focused on building a scaled, differentiated security platform," said Andy Cook, a Partner at Southfield Capital. "The addition of AT-RISK International strengthens Protos' leadership position and accelerates its evolution into a premier provider of integrated protection solutions at scale."

The New Frontier of Protective Services

The acquisition directly addresses the changing nature of risk in a globalized world. Corporate leaders and high-profile individuals face a complex and unpredictable threat landscape, ranging from physical security risks and geopolitical instability to cyber threats and reputational attacks. In response, the demand for sophisticated, personalized protection has surged.

AT-RISK International is a leader in this niche, offering more than just traditional bodyguard services. The firm operates a state-of-the-art Global Risk Intelligence Center that provides continuous monitoring and analysis, allowing for proactive threat mitigation rather than reactive responses. Its services include discreet protective details, residential security for high-net-worth families, secure transport, and comprehensive risk consulting for organizations entering new markets or facing unique challenges.

By integrating these capabilities, Protos is positioning itself as a one-stop shop for holistic risk management. "Joining Protos Security enables us to scale our capabilities and deliver even greater value for AT-RISK's clients," said Chuck Tobin, President and CEO of AT-RISK International. Tobin, who will remain in his leadership role, emphasized the synergy between the two companies. "By combining our expertise in protective services and risk consulting with Protos' extensive service network and software platform, we are uniquely positioned to deliver comprehensive, end-to-end intelligence-led solutions for clients facing increasingly complex global security challenges."

Integrating for Scale and Service

A key challenge in any acquisition is successful integration. Protos and AT-RISK aim to mitigate disruption and maximize synergy by maintaining AT-RISK's brand and leadership structure. This strategy is intended to reassure existing AT-RISK clients and employees, ensuring continuity of service and expertise while beginning the process of technological and operational integration.

For clients of both companies, the merger promises significant benefits. Protos' customers gain access to a suite of elite global intelligence and protective services previously unavailable through the platform. Conversely, AT-RISK’s clients can now leverage Protos' vast North American service network for scaled physical security needs, all managed through a unified software platform that provides enhanced visibility and data-driven insights.

The combined entity will focus on delivering a more comprehensive security offering, increased scalability, and continued innovation. By wedding AT-RISK’s high-touch, advisory-driven approach with Protos’ technology-first, scalable service model, the company aims to create a new standard for integrated security in the industry, capable of protecting assets and people from the local to the global level.
