Radiflow iSID
What it is
Radiflow iSID provides OT network visibility, monitoring, and threat detection for industrial operations and critical infrastructure. It passively observes network traffic to discover assets and create an inventory that records their roles and impacts on the OT environment. The system learns normal network, asset, and communication behavior to detect deviations, and uses threat intelligence, SNORT-based and common attack signatures, and CVE mapping to identify known threats and vulnerabilities. Its deep packet inspection analyzes mirrored traffic, while monitoring tracks configuration changes in PLCs and other network devices without disrupting operations. iSID can be deployed centrally with iSAP Smart Collectors, locally at remote sites, or in a combination. The iCEN web interface provides enterprise-wide and site-specific views and manages 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. Radiflow serves industrial enterprises and utilities, including critical infrastructure operators. Pricing is available on request.
For and against
For
