Summary

Radiflow iSID provides OT network visibility, threat detection, and monitoring for industrial operations and critical infrastructure. It passively monitors network traffic to discover assets and build an inventory with each asset’s role and impact on the OT environment. It learns normal network, asset, and communication behavior to detect deviations, alongside known threats and vulnerabilities identified using threat intelligence, SNORT-based and common attack signatures, and CVE mapping. Deep packet inspection analyzes mirrored traffic without disrupting operations, while continuous monitoring checks PLCs and other network devices for configuration changes. iSID can be deployed centrally using iSAP Smart Collectors, locally at remote sites, or through a mix of both. The iCEN web interface provides enterprise-wide and site-specific views and central management of multiple iSID instances. MSSPs can manage multiple customers with client-based view permissions. A documented Cisco ISE integration shares OT asset context through pxGrid and supports quarantine policies. The product is offered as self-hosted software or through the web; pricing is available on request.
