Belden and Radiflow Partner to Close the Gap Between OT Threat Detection and Network Response
New partnership delivers automated, machine-speed security enforcement for industrial operators – powered by integrating Radiflow's CIARA with Belden NAC, formerly macmon NAC
ST. LOUIS, October 23, 2026--Belden Inc. (NYSE: BDC), a leading global provider of complete connection solutions, today announced a strategic partnership with Radiflow, a leading global provider of OT cybersecurity solutions and services for critical infrastructure and industrial automation, particularly within discrete industries. Together, the companies will enable automated, intelligence-driven security enforcement across operational technology environments, closing the critical gap between threat detection and network response.
As OT environments become increasingly connected, security teams face a growing challenge. Understanding operational risk is no longer enough. Organizations must be able to act on that intelligence immediately. While OT security platforms excel at identifying vulnerabilities, exposures and anomalous behavior, the enforcement of security policies often remains a separate and largely manual process. Bridging the gap between OT visibility and automated network access control is essential to reduce response times and limit cyber risk in critical operations.
Together, Belden and Radiflow address this challenge directly by creating a unified security loop. Radiflow's platform delivers asset discovery, risk assessment and continuous anomaly detection across OT environments; Belden contributes trusted network infrastructure and access control, closing the loop from detection to enforcement. Today, the companies are launching an integrated solution that puts this loop into action: exposure detection and network enforcement working as one system, moving from "we found a new risk" to "access is restricted" without a manual handoff in between.
Radiflow's CIARA (Cyber Intelligence and Risk Assessment) maps an organization's OT network topology and layers on AI-driven threat intelligence to continuously flag critical exposures as they emerge, not weeks later. Together, iSID (Industrial Secure Intrusion Detection) and CIARA integrate with BeldenNAC, formerly macmon NAC. iSID delivers real-time OT event context while CIARA enriches Belden NAC with current risk scores per asset and zone. This enables Belden NAC to trigger automatic access-right adjustments the moment risk posture changes, delivering the continuous, contextual response OT security demands as AI accelerates the threat landscape.
