Belden Inc., a leading global provider of complete connection solutions, has announced a strategic partnership with Radiflow, a leading global provider of OT cybersecurity solutions and services for critical infrastructure and industrial automation. Together, the companies will enable automated, intelligence-driven security enforcement across operational technology environments, closing the critical gap between threat detection and network response.
Belden and Radiflow have partnered to close the gap between OT threat detection and network response.
The integrated solution combines Radiflow's CIARA and iSID with Belden NAC, formerly macmon NAC.
CIARA maps an organization's OT network topology and layers on AI-driven threat intelligence to flag critical exposures as they emerge.
iSID delivers real-time OT event context while CIARA enriches Belden NAC with current risk scores per asset and zone.
Belden NAC triggers automatic access-right adjustments the moment risk posture changes.
Radiflow's solutions are already deployed at more than 20,000 sites worldwide.
"This partnership reflects exactly where Belden is heading: delivering security solutions that are comprehensive and immediately actionable in the field," said Alexandre Peixoto, VP Security at Belden. "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."
"Belden's network infrastructure expertise is a natural complement to Radiflow's risk intelligence capabilities," said Ilan Barda, CEO, Radiflow. "Together, we give industrial operators what they've been missing: a direct, automated path from identifying a threat to enforcing the right response at machine speed, without putting operations at risk."
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.
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. The integrated solution moves from "we found a new risk" to "access is restricted" without a manual handoff in between.
This collaboration extends Belden's commitment to delivering complete, end-to-end connectivity and security solutions for the most demanding industrial environments — from manufacturing and energy to transportation and critical infrastructure. With Radiflow's solutions already deployed at a significant number of sites worldwide, the partnership brings immediate scale and operational depth to joint customers across the Americas and EMEA.
