Radiflow iSID provides OT network visibility, threat detection and monitoring for industrial operations and critical infrastructure. It passively analyzes mirrored network traffic to discover OT assets and build an inventory that records their roles and impacts on the environment. The system learns normal network, asset and communication behavior, then detects deviations alongside known threats and vulnerabilities using threat intelligence, SNORT-based and common attack signatures, and CVE mapping. It also monitors configuration changes in PLCs and other network devices without disrupting operations. Deployment can be centralized with iSAP Smart Collectors, placed locally at remote sites, or use a mix of both. The iCEN web interface offers enterprise-wide and site-specific views and centralized 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 Adaptive Network Control quarantine policies. The iSID 6.0 guide specifies Google Chrome for browser management. Radiflow describes its solutions as serving industrial enterprises and utilities, including critical infrastructure operators. Pricing is available on request.
