Radiflow iSID vs Rhebo Industrial Protector

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.

Rhebo Industrial Protector is a network-based intrusion detection system for operational technology networks. It continuously monitors OT communications and uses anomaly detection to identify cyberattacks, tampering, and technical failures. Its passive design connects through mirror ports or network taps without modifying OT infrastructure, aiming to avoid disruption to industrial processes. Real-time cyber-event reporting includes detailed PCAP records. The system visualizes active devices, firmware status, protocols, connections, and known vulnerabilities for OT documentation and asset management. Standard-based SIEM integration can bring OT security events into enterprise cybersecurity systems. Rhebo offers on-premises and off-premises deployment, including physical and virtualized on-premises appliances; VMware ESXi is listed for virtual deployments. Specifications state that all OT communication protocols are detected and logged, with OPC, IEC 60870-5-104, IEC 61850-8-1, and DNP3 listed. Rhebo identifies critical infrastructure, utilities, and manufacturing as intended users.
