DeNexus has joined the ISA Global Cybersecurity Alliance (ISAGCA), the collaborative forum created by the International Society of Automation to strengthen OT cybersecurity through education, knowledge sharing, and the ISA/IEC 62443 series of standards.

Our reason for joining is straightforward, and it goes to the heart of why the company exists.
Industrial cyber risk has been invisible to the people who carry it — boards, CFOs, and the risk transfer market that could underwrite it. Part of the reason is that OT security has lacked a common language for how controls are designed and assessed across an industry of very different plants, vendors, and architectures.
The ISA/IEC 62443 series provides that language. It gives asset owners, integrators, and product suppliers a shared reference for what "secure" means across the OT lifecycle — from system design and integration through operations and maintenance. That shared reference is the precondition for everything that follows: a risk you can describe in common terms is a risk you can assess, and a risk you can assess is one you can quantify, reduce, and transfer.
DeNexus delivers an evidence-based approach to OT cyber risk quantification: visibility into each facility's cyber exposure, the probability and financial impact of potential incidents expressed as Expected Annual Loss and Value at Risk, and mitigation prioritized by return on investment. As our founder and CEO, Jose M. Seara, put it:
"ISA/IEC 62443 gives the industry a shared language for control, and our platform turns that control state into a financial number a board can govern by and an underwriter can price against. Joining ISAGCA puts us alongside the organizations building that foundation."
That connection — from a documented control state to a defensible financial figure — is what lets the same evidence base serve the boardroom, the security roadmap, and the underwriting submission.
ISAGCA brings together leading industrial operators, technology vendors, and standards bodies working to strengthen OT security. We're glad to add our OT cyber risk quantification perspective to that community and to support broader adoption of ISA/IEC 62443.
The work is already underway. Jose led a session at the ISA OT Cybersecurity Summit in Prague in June 2026, "OT Cyber Insurance and Risk Transfer: Right-Sizing Coverage Using Evidence, Not Guesswork," and delivered an encore of that session by webinar in September.
