Industrial cybersecurity firm Dragos has acquired Phosphorus in a move to extend protection across the billions of connected devices now embedded in critical infrastructure and operational networks. The acquisition expands the Dragos Platform's coverage beyond traditional operational technology systems to address the growing security challenges posed by diverse connected devices.
Operational environments in critical infrastructure have evolved significantly beyond their traditional boundaries. Power grids, pipelines, manufacturing facilities, and data centers now rely on an increasingly complex mix of connected devices and digital systems that extend far beyond conventional industrial control systems and supervisory control and data acquisition (SCADA) networks.
The technical challenge stems from the proliferation of both traditional and non-traditional assets throughout operational environments. These connected devices, which number in the billions across critical infrastructure sectors, create an expanded attack surface that conventional OT security tools were not designed to address. Phosphorus brings capabilities specifically focused on managing and securing these diverse connected endpoints that have become integral to modern operational networks.
The acquisition reflects a broader industry shift in how organizations must approach OT security. As operational technology converges with information technology and IoT devices, security teams face the challenge of protecting an increasingly heterogeneous environment where traditional OT security boundaries no longer adequately define the threat landscape.
Organizations operating critical infrastructure should evaluate their current security posture to ensure coverage extends beyond traditional OT systems to include all connected devices in their operational environments. Security teams should inventory connected devices across their networks and assess whether existing security tools provide adequate visibility and protection for these expanded operational technology environments.
