Under the agreement, Dragos will combine its OT threat detection platform with runZero’s attack surface management capabilities and NetRise’s software supply chain and firmware visibility technology. The companies will operate under the Dragos brand, which will continue to function independently under co-founder and CEO Robert M. Lee.
Accenture said the deal comes as industrial environments become increasingly interconnected and AI accelerates both defensive and offensive cyber capabilities. The company believes AI-driven threat activity is compressing the time between an IT breach and attacks targeting operational systems, creating new risks for critical infrastructure operators.
“In an age when AI-driven cyber threats and geopolitical risk are evolving at a rapid pace, our cybersecurity practice is growing by double-digits and has a strong track record of leveraging inorganic opportunity to fuel organic growth,” Julie Sweet, chair and CEO of Accenture, said in a June 19 statement.

“Our clients across industries and regions are asking us how to be more proactive and integrated in their approach to cybersecurity. The addition of Dragos, complemented by runZero and NetRise, fills this important need.”
Lee added that organisations are increasingly requiring integrated platforms rather than standalone security products.
“Our energy and water systems, manufacturing plants, data centres and other operational environments need cybersecurity built from the ground up for xOT and designed to keep pace as threats evolve,” Lee said.

“The consequences of getting it wrong become societal threats.”
Accenture’s cyber security business grew from US$700 million in revenue in 2016 to US$10 billion in fiscal year 2025. Accenture estimates the broader OT cyber security market will grow from US$27 billion in 2026 to almost US$59 billion by 2031.
The transactions are expected to close in August or September 2026, subject to regulatory approval and customary closing conditions.
