Claroty Secures the Machines You Can’t Just Reboot
Factories, hospitals, and airports need cybersecurity that respects the machinery. Claroty has built its business around a difficult promise: find the risk without stopping the work.
Nozomi Networks Found a $1 Billion Business in the Networks Factories Were Afraid to Touch - Here’s the Playbook
Two researchers built a security company around an awkward industrial truth: you cannot defend machines you cannot see, and you cannot casually probe machines that keep cities running. Their passive-first wedge became a global platform, more than $100 million in annual revenue, and a $1 billion acquisition.
Robert M. Lee Is Building Cybersecurity for the Machines That Keep Civilization Running
Before industrial cybersecurity had a common language, Lee was helping invent one. Now the Dragos co-founder is trying to turn hard-won lessons from grids, pipelines and factory floors into a durable system of defense.
Dragos Turned a Three-Person Side Project Into Security for the Machines Nobody Can Reboot
Dragos began with three practitioners, a packet-capture tool, and a founder who did not want to become a software vendor. A decade later, its field notes defend grids, factories and water systems - and explain why industrial security cannot be treated like office IT.
Rockwell Automation
It started in 1903 with a $1,000 bet on a better motor controller. A century later, Rockwell Automation runs the machinery behind cars, medicine and microchips - and is quietly wiring the factory floor into the cloud.
Honeywell Technologies
After spinning off aerospace and advanced materials, Honeywell is smaller, sharper and focused on one difficult job: teaching the physical world to run with less waste, fewer surprises and more autonomy.
DeNexus
DeNexus is a Boston-based cyber risk company that quantifies the financial impact of cyber threats to industrial and operational technology (OT) environments. Its DeRISK platform uses AI, machine learning and simulation to predict where breaches are likely in OT/ICS networks, express that risk in dollar terms, and prioritize mitigation by ROI. The company serves CISOs, boards, risk managers and cyber insurers across data centers, energy, manufacturing and transportation, and has expanded into agentic-AI underwriting automation for the industrial cyber insurance market.
Jose Seara
Jose Seara is the founder and CEO of DeNexus, a Boston-based company that quantifies cyber risk for operational technology and industrial control systems. A naval and marine engineer by training, he spent nearly two decades building critical infrastructure and renewable energy companies across Europe and North America before pivoting to cybersecurity. He started DeNexus after discovering, as an energy operator, that he could not measure his own company's cyber risk or insure against it. His DeRISK platform turns technical threat data into financial metrics that boards and insurers can act on.
Dispel
Dispel is an Austin, Texas-based operational technology (OT) cybersecurity company that builds a Zero Trust Engine for industrial control systems. Its platform combines secure remote access, real-time industrial data streaming, unified OT connectivity (OTFusion), and 24/7 threat monitoring, all built around Moving Target Defense - a technique that constantly shifts network paths so attackers never get a stable target. Dispel lets manufacturers, utilities, energy operators, and government agencies give vendors and engineers fast, audited access to plant equipment without the friction of legacy VPNs and jump boxes.
