DeNexus Joins the ISA Global Cybersecurity Alliance

On September 22, 2026, DeNexus has made headlines by officially joining the International Society of Automation (ISA) Global Cybersecurity Alliance (ISAGCA), marking a significant step towards promoting operational technology (OT) cybersecurity standards. This partnership not only reaffirms DeNexus's dedication to enhancing cybersecurity practices across the OT landscape but also aims to foster broader adoption of the ISA/IEC 62443 standards, which are pivotal in safeguarding operational environments.

The ISA Global Cybersecurity Alliance serves as a collaborative forum designed to amplify awareness and education regarding OT cybersecurity. Its mission includes knowledge sharing among notable industry leaders and enhancing cybersecurity resilience through standardization and best practices. With DeNexus on board, the alliance is poised to strengthen its efforts to establish robust cybersecurity frameworks that address the growing threats in today’s digital landscape.

DeNexus, best known for its comprehensive solutions that enable industrial stakeholders to assess their cyber exposure effectively, offers an evidence-based approach to understanding potential risks. Their platform allows organizations to calculate the probability of cyber incidents occurring, measure the financial implications, and prioritize risk mitigation strategies based on essential key performance indicators (KPIs). Through this partnership with ISAGCA, DeNexus aims to further its commitment to providing industry-focused, standards-driven security practices throughout the OT lifecycle—from system design and integration to ongoing operations and maintenance.

Founder and CEO of DeNexus, Jose M. Seara, recently showcased his expertise at the ISA OT Cybersecurity Summit held in Prague in June 2026. During his presentation titled "OT Cyber Insurance and Risk Transfer: Right-Sizing Coverage Using Evidence, Not Guesswork," he emphasized the importance of transforming the often invisible risks associated with industrial cybersecurity into quantifiable metrics that organizations can manage and control. This idea was so well-received that he conducted a follow-up webinar in September to address the continuous interest in this vital topic.

As DeNexus collaborates with ISAGCA and fellow industry leaders, their focus will be on accelerating the adoption of the ISA/IEC 62443 standards framework across various sectors. “This is a significant moment for the ISAGCA community,” remarked Michelle Ritterskamp, program coordinator of ISAGCA. With a deep technical background in OT, DeNexus is expected to enrich this initiative with invaluable insights and share its expertise across future projects.

Reflecting on the importance of cyber risk visibility, Seara articulated, "Industrial cyber risk has been invisible to the people who carry it—boards, CFOs, and markets that provide underwriting. This issue is what inspired the formation of DeNexus and aligns with ISA/IEC 62443’s focus on creating a unified standard for designing and assessing OT security.” He also pointed out that the shared standards and language played a critical role in making risks assessable, quantifiable, and manageable.

Joining the ISAGCA aligns with DeNexus’s mission of making industrial cyber risk quantifiable for stakeholders such as boards, investors, and the insurance market. By focusing on standards and collaborative industry efforts, the path to scaling effective risk management practices becomes a shared responsibility.
