How to automate OT threat response: Belden and Radiflow integration

Automated, intelligence-driven security enforcement across OT environments.

Operational technology teams know the pain: platforms flag vulnerabilities and anomalies, but enforcing a policy change still requires a manual handoff between the SOC and the network team. That delay is where attackers operate. A new partnership between Belden and Radiflow aims to close that gap by linking OT risk intelligence directly to network access control. Softprom is the official distributor of Belden.

What was announced

On October 23, 2026, Belden Inc. (NYSE: BDC) and Radiflow announced a strategic partnership and an integrated solution that connects Radiflow's OT threat detection and risk assessment platforms with BeldenNAC (formerly macmon NAC). The goal: move from we found a new risk to access is restricted without a manual step in between.

Radiflow's CIARA (Cyber Intelligence and Risk Assessment) maps the OT network topology and applies AI-driven threat intelligence to flag critical exposures continuously. iSID (Industrial Secure Intrusion Detection) adds real-time OT event context. Together they feed updated per-asset and per-zone risk scores into BeldenNAC, which triggers automatic access-right adjustments the moment the risk posture changes.

With Radiflow's CIARA and iSID platform providing continuous, data-driven risk intelligence and exposure detection, combined with Belden enforcing it at the network level, joint customers across manufacturing, energy and critical infrastructure get both the insight and the response from day one

Why this matters

For CIOs, CISOs and OT directors in manufacturing, energy, transportation and critical infrastructure, the integration shortens the time between detection and containment. Instead of security analysts opening tickets for network engineers to adjust VLANs or ACLs, the NAC layer reacts to live risk telemetry automatically. That reduces dwell time, limits lateral movement, and lowers the operational cost of OT security as the AI-driven threat landscape accelerates.

Technical details

• CIARA: OT network topology mapping, AI-driven risk assessment, continuous exposure detection.
• iSID: industrial intrusion detection with real-time OT event context.
• BeldenNAC (formerly macmon NAC): network access control with automatic access-right adjustments based on live risk scores.
• Integration model: risk scores per asset and zone are pushed from CIARA and iSID into BeldenNAC to trigger policy enforcement without manual handoff.
• Target environments: discrete manufacturing, energy, transportation and other critical infrastructure sectors across the Americas and EMEA.

FAQ

What problem does the Belden and Radiflow integration solve?

It closes the gap between OT threat detection and network response. Risk signals from CIARA and iSID directly drive BeldenNAC enforcement, so access is restricted automatically when an asset's risk posture changes.

Is BeldenNAC the same product as macmon NAC?

Yes. BeldenNAC is the new name for macmon NAC. It provides network access control and now consumes OT risk telemetry from Radiflow to automate policy enforcement.

Which industries benefit most from this integrated OT security approach?

Manufacturing, energy, transportation and other critical infrastructure operators with converged IT/OT networks, where manual coordination between detection and enforcement creates measurable risk.
