Phosphorus acquired by Dragos

Phosphorus is a US-based company specializing in cybersecurity for extended operational technology (xOT) environments, encompassing both traditional industrial control systems (OT) and the vast array of connected devices deployed in critical infrastructure. The company has developed a platform for discovering and managing connected assets, enabling the identification, securing, and monitoring of devices that often fall outside the visibility of traditional cybersecurity tools. Its technology is built around a continuous visibility approach to equipment, combined with automated remediation capabilities, including password management, certificate management, configuration management, and security updates. As a result, Phosphorus operates in complex environments such as industrial networks, energy sites, transportation infrastructure, and data centers, where the attack surface has expanded significantly with the proliferation of connected devices. Prior to the transaction, the company was backed by several international venture capital investors and had completed multiple successful funding rounds.
