Dragos, a cybersecurity company specializing in operational technology (OT) environments, has acquired Phosphorus, a provider of connected device security solutions. The acquisition expands the Dragos Platform beyond traditional OT systems, helping organizations secure the growing number of connected devices operating across critical infrastructure networks.
Securing the Extended OT Environment
Modern operational environments now include billions of connected devices across sectors such as energy, manufacturing, transportation, and data centers. This broader landscape, known as Extended Operational Technology (xOT), requires greater visibility and control to address evolving cyber threats.
“The connected devices you find everywhere in critical infrastructure are largely invisible to the cybersecurity programs that protect operational environments,” said Robert M. Lee, CEO and Co-Founder of Dragos. “With Phosphorus, we close that gap and secure xOT, the full environment that matters.”
Expanding Device Visibility and Remediation
Phosphorus provides device discovery, risk assessment, and automated remediation capabilities across operational and enterprise environments. The platform helps organizations manage password rotations, firmware updates, certificate management, and security configurations while improving compliance and reducing risk.
“We built Phosphorus to solve the connected device problem — the unmanaged devices, the default credentials, the firmware no one was updating. Together with Dragos, we can solve it with a depth and scale that wasn’t possible before. That’s what the next generation of OT cybersecurity looks like,” said Sonu Shankar, President and COO of Phosphorus.
Strengthening the Dragos Platform
The acquisition follows Dragos’ 2024 acquisition of Network Perception, which added network visibility and segmentation capabilities. Combined with Phosphorus’ device security technology, Dragos aims to provide comprehensive protection across the entire xOT environment. Phosphorus customers will continue to receive support while gaining access to broader Dragos capabilities as integration progresses.
