Accenture closes $4.1B majority stake deal for OT security firm Dragos

The all-in package quietly folds in two more startups, giving one consulting giant more control over how factories, grids and refineries defend themselves.

• Accenture completed its majority stake acquisition of industrial cybersecurity firm Dragos on September 21, 2026, part of a combined $4.1 billion deal that also included Dragos buying runZero and NetRise.
• Dragos, based in Hanover, Maryland, builds software that defends physical operational systems—electric grids, oil and gas, manufacturing and data centers—from cyberattacks.
• SecurityWeek reports Accenture valued its majority stake in Dragos at an enterprise value of $3.25 billion, with the runZero and NetRise acquisitions making up the rest of the $4.1 billion total.
• Dragos CEO Robert M. Lee was named Chairman of the Board, and CrowdStrike co-founder Dmitri Alperovitch is returning to Dragos's board alongside new directors appointed by Accenture.
• The runZero and NetRise deals follow Dragos's earlier 2026 acquisition of Phosphorus, rounding out what the company calls an 'xOT' platform covering connected devices, cloud, software supply chains and core OT threat detection.
• A global consulting firm taking control of a leading OT security vendor underscores how critical-infrastructure defense is shifting from a niche specialty to a core enterprise security priority, in a year that has already seen more than 280 cybersecurity M&A deals.
