_Dragos expands to protect xOT including OT systems and the billions of connected
devices that have reshaped how critical infrastructure operates_

HANOVER, Md., June 2, 2026 /PRNewswire/ — Dragos, the global leader in cybersecurity
for operational technology (OT) environments, today announced it has acquired Phosphorus,
extending the Dragos Platform to protect the billions of connected devices embedded
across critical infrastructure and other operational networks.

Operational environments have outgrown traditional OT boundaries. Power grids, pipelines,
manufacturing facilities, and data centers now depend on an increasingly diverse
mix of connected devices and digital systems. Traditional and non-traditional assets
alike are woven throughout their operational environments. This expanded environment—
OT systems and the billions of connected devices that have reshaped how critical
infrastructure operates — is the Extended Operational Technology environment, or
xOT. Adversaries are already operating across it. Defenders need a broader scope
of visibility, intelligence, and control to defend it.

Dragos’s acquisition of Phosphorus reflects a deliberate strategy to protect the
full operational environment as it exists and operates today. Dragos offers the 
industry’s most comprehensive OT cybersecurity platform. Adding Phosphorus extends
Dragos capabilities to secure connected devices across the full xOT environment,
delivering deeper device visibility, automated remediation, and continuous risk 
reduction.

"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."

"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.

Phosphorus offers the industry’s most comprehensive discovery and remediation platform
for connected devices, which integrates with customers’ existing infrastructure 
without requiring disruptive architectural changes. The platform actively discovers
and provides deep visibility into devices across OT and enterprise environments,
delivering detailed risk context and continuous situational awareness across the
extended device landscape. Phosphorus automates remediation workflows, including
password rotations, firmware updates, certificate management, and configuration 
hardening, while helping organizations address compliance and reduce risk at scale.

Dragos customers will gain expanded asset visibility and integrated device intelligence
in the near term, with automated remediation workflows and a unified platform experience
to follow.  Phosphorus customers will continue to be fully supported, with expanded
access to Dragos offerings as integration progresses. Sonu Shankar will continue
to lead the Phosphorus business as a General Manager within Dragos, through a structured,
phased integration.

With the addition of Phosphorus, Dragos estimates its total addressable market opportunity
at more than $50 billion.* The acquisition builds on Dragos’s October 2024 acquisition
of Network Perception, which added expanded OT network visibility, segmentation 
validation, and compliance to the Dragos platform. Where Network Perception maps
and secures the network architecture, Phosphorus secures the devices running on 
it.
