Dragos Acquires Phosphorus to Extend OT Platform Into xOT

The deal is intended to close visibility gaps for unmanaged connected devices across critical infrastructure by folding Phosphorus’s device-discovery and remediation tools into a phased Dragos integration that preserves Phosphorus as a separate business unit.

Overview

  • Dragos announced the acquisition of Phosphorus on Monday, June 1, 2026, saying the move immediately expands asset visibility for its customers and will later add automated remediation and unified workflows.
  • Phosphorus, a Nashville company founded in 2017, provides large-scale device discovery, device-level risk context, and automated remediation actions such as password rotation, firmware updates, certificate management, and configuration hardening.
  • Phosphorus will remain supported as a business unit led by Sonu Shankar acting as general manager while the companies carry out a structured, phased product integration.
  • Financial terms and a full timeline for product integration were not disclosed, and both firms said existing customers of each platform will continue to receive support during the transition.
  • Dragos framed the acquisition as part of a platform consolidation strategy that builds on its October 2024 Network Perception deal and said the move increases its total addressable market to more than $50 billion based on third-party research, a shift that could accelerate industry focus on securing the extended OT environment.
