Radiflow iSID provides OT network visibility, threat detection, and monitoring for industrial operations and critical infrastructure. It passively observes network traffic to identify assets and build an inventory that records their roles and effects on the OT environment. By learning typical network, asset, and communication behavior, it detects deviations as well as known threats and vulnerabilities using threat intelligence, signatures, and CVE mapping. Deep packet inspection analyzes mirrored traffic, while continuous monitoring checks PLCs and other network devices for configuration changes without disrupting operations. Deployment can be centralized with iSAP Smart Collectors, placed locally at remote sites, or split between both approaches. The iCEN web interface offers site-specific and enterprise-wide views and central management of multiple iSID instances; MSSPs can manage multiple customers with client-based view permissions. A documented Cisco ISE integration exchanges OT asset context through pxGrid and supports quarantine policies. iSID is available as self-hosted software or through the web, and pricing is available on request.
Who it is for
iSID is intended for industrial enterprises, utilities, and critical infrastructure operators that need OT asset visibility and monitoring. Its multiple-instance management and separated customer views also suit MSSPs.
