# Industry News: DeNexus Joins ISAGCA to Bridge OT Security and Financial Risk
## Summary
DeNexus, a leader in cyber risk quantification, has officially joined the ISA Global Cybersecurity Alliance (ISAGCA) to accelerate the adoption of ISA/IEC 62443 standards. This partnership focuses on translating technical OT security controls into financial risk metrics for better corporate governance and insurance underwriting.
## Key Details
- **Date:** September 28, 2026
- **Companies Involved:** DeNexus, International Society of Automation (ISA)
- **Category:** Partnership / Industry Alliance
## The Story
The International Society of Automation (ISA) announced that DeNexus has joined its Global Cybersecurity Alliance (ISAGCA). This move is designed to integrate DeNexus’s evidence-based risk quantification platform with the globally recognized ISA/IEC 62443 standards.
DeNexus focuses on making industrial cyber risk visible to executive leadership by calculating the financial probability of incidents and prioritizing mitigation strategies based on ROI. By joining the ISAGCA, DeNexus aims to utilize the 62443 framework as the "shared language" for control, which their platform then converts into actionable financial data. This collaboration follows DeNexus CEO Jose M. Seara’s recent industry engagements regarding the use of evidence-based data to right-size cyber insurance coverage for industrial stakeholders.
## Business Impact
### For the Companies Involved
- **DeNexus:** Gains significant credibility and a seat at the table with global policy-makers and standard-setters, validating their risk-quantification model against the industry’s primary OT standard.
- **ISA/ISAGCA:** Benefits from DeNexus’s expertise in insurance and financial risk, helping to bridge the gap between technical standards and C-suite decision-making.
### For Competitors
- Competitors in the OT risk management space may face pressure to more tightly integrate their platforms with formal standards like 62443 to remain relevant to large-scale industrial enterprises and insurers.
### For Customers
- End users (CFOs and Asset Owners) gain a more direct path to justifying security spend. The alignment ensures that technical improvements in security posture (via 62443) translate directly into quantifiable risk reduction and potentially better insurance premiums.
### For the Market
- This signals a maturing OT market where security is no longer just a technical requirement but a financial and governance necessity. It highlights the growing trend of "Risk Transfer," where insurance markets play a larger role in industrial cybersecurity.
## Technical Implications
The partnership emphasizes the operationalization of **ISA/IEC 62443**. While the standard defines "how" to secure systems, DeNexus provides the telemetry and data layer to measure the "effectiveness" of those controls in financial terms. This requires deep technical visibility into OT facility exposure and the ability to map technical failures to business downtime costs.
## Strategic Analysis
- **Market Positioning:** DeNexus is positioning itself as the critical link between the server room and the boardroom.
- **Competitive Advantage:** By aligning with ISAGCA, DeNexus ensures its proprietary risk algorithms stay synchronized with international regulatory and technical benchmarks.
- **Challenges:** The primary obstacle remains the diversity of legacy OT environments; creating a "universal" financial risk model that fits every unique industrial facility remains a complex undertaking.
## Industry Reactions
- **ISAGCA (Michelle Ritterskamp):** Highlighted DeNexus’s deep technical OT experience and their proactive desire to incorporate 62443 into business-centric risk models.
- **DeNexus (Jose M. Seara):** Stated that standards are the foundation that makes industrial cyber risk "assessable, quantifiable, and transferable."
## Future Outlook
- **Predictable Standards-Based Insurance:** Expect to see the insurance industry move toward requiring adherence to ISA/IEC 62443 as a prerequisite for OT coverage.
- **C-Suite Engagement:** Watch for increased development of "Cyber-to-Financial" dashboards that allow boards to govern OT risk similarly to market or credit risk.
## For Security Professionals
Practitioners should prioritize mapping their current security initiatives to the ISA/IEC 62443 framework. As risk quantification becomes a standard requirement for insurance and board reporting, the ability to demonstrate compliance with these standards will be the primary way to secure budget and prove the ROI of security investments.
