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.
