The International Society of Automation (ISA), a leading professional organization in the automation industry, has announced that DeNexus has officially joined the ISA Global Cybersecurity Alliance (ISAGCA). This move underscores DeNexus’s commitment to strengthening operational technology (OT) cybersecurity and supporting the adoption of the ISA/IEC 62443 series of standards.
Created by ISA, the ISA Global Cybersecurity Alliance is a collaborative forum focused on strengthening OT cybersecurity through education, knowledge sharing, and industry collaboration. Leveraging the widely used ISA/IEC 62443 standards, ISAGCA works to expand cybersecurity expertise, openly share knowledge and resources, and protect the OT cybersecurity worldwide community.
DeNexus delivers an evidence-based solution for OT industrial stakeholders to gain visibility into each facility’s cyber exposure, calculate the probability and financial impact of potential cyber incidents, and prioritize risk mitigation based on ROI or other KPIs. By joining ISAGCA, DeNexus underscores its commitment to supporting standards-driven security practices across the OT lifecycle from system design and integration to operations and maintenance.
DeNexus founder and CEO Jose M. Seara spoke at the ISA OT Cybersecurity Summit in Prague in June 2026, leading a session titled “OT Cyber Insurance and Risk Transfer: Right-Sizing Coverage Using Evidence, Not Guesswork.” Based on interest, he also conducted an encore presentation on the topic via webinar in September. Through ISAGCA membership, DeNexus will collaborate with global industry leaders to accelerate awareness, adoption and implementation of the ISA/IEC 62443 standards framework.
“This is a significant moment for the ISAGCA community. DeNexus brings a deep OT technical experience and a desire to incorporate ISA/IEC 62443 into their business. ISAGCA staff would like to thank DeNexus for the excellent collaboration on programs already, and we look forward to further sharing DeNexus’ expertise in future initiatives.”
-Michelle Ritterskamp, ISAGCA program coordinator
“Industrial cyber risk has been invisible to the people who carry it — boards, CFOs and the markets that could underwrite it. That’s the problem I started DeNexus to solve, and it’s the same problem ISA/IEC 62443 addresses from the standards side. A common standard for how OT security is designed and assessed is what makes risk assessable in the first place. And once risk can be assessed, it can be quantified, mitigated and transferred. That’s the chain: 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. Our mission is to make industrial cyber risk quantifiable for boards, investors and the risk transfer market — and standards are what make that possible at scale.”
-Seara
The ISA Global Cybersecurity Alliance (ISAGCA) is a collaborative forum to advance OT cybersecurity awareness, education, readiness, standardization, and knowledge sharing. ISAGCA’s global ecosystem includes leaders such as Chevron, GSK, Trane Technologies, Honeywell, Johnson Controls, Schneider Electric, Rockwell Automation and Fortinet, among others.
CISOs, OT facility managers, cybersecurity practitioners, executive boards and insurers need better quantification of cyber risks across their fleet of operational technology (OT) assets to enable efficient risk management and transfer. DeNexus delivers an evidence-based solution for OT industrial stakeholders to gain visibility into each facility’s cyber exposure, calculate the probability and financial impact of potential cyber incidents, and prioritize risk mitigation based on ROI or other KPIs.
The International Society of Automation (ISA) is a non-profit professional association founded in 1945 to create a better world through automation.
