Dragos Acquires Phosphorus to Bring OT-Native Cybersecurity to the Full xOT Environment
Summary: Dragos announced on June 1, 2026 that it has acquired Phosphorus, extending the Dragos Platform to protect the billions of connected devices embedded across critical infrastructure and operational networks. Dragos describes the combined scope as the Extended Operational Technology environment, or xOT, and says Phosphorus adds device discovery, visibility, and automated remediation including password rotations, firmware updates, certificate management, and configuration hardening.
What's compelling: Phosphorus's own president names the problem plainly: unmanaged devices, default credentials, and firmware no one was updating - the same conditions that sit inside power grids, pipelines, and water systems. Dragos puts its total addressable market at more than $50 billion, a measure of how much unprotected connected device estate vendors expect to find.
