Radiflow

What Radiflow does

Radiflow is an Israel-based operational technology (OT) cybersecurity company founded in 2009 and headquartered in Tel Aviv, operating as a subsidiary of the Sabanci Group. The company provides a unified platform for protecting industrial control systems (ICS) and SCADA environments in critical infrastructure sectors, including manufacturing, power generation and transmission, oil and gas, water/wastewater, maritime, transportation, and increasingly data centers, healthcare, and financial services. Radiflow's core technology stack combines passive deep-packet-inspection network monitoring with behavioral anomaly detection (iSID), an ML-driven breach-and-attack simulation engine for risk-based prioritization (CIARA), and centralized multi-site management (iCEN), complemented by active asset scanning, hardware smart collectors with patented 1:10 traffic compression for bandwidth-constrained remote sites (vSAP RF-2180, iSAP), and secure gateways (iSEG). The October 2025 launch of Radiflow360 extends the portfolio into a lifecycle-wide visibility and control platform.

The company monetizes through annual software subscriptions, hardware appliance sales, and professional services delivered via certified partners. Go-to-market is enterprise field sales with regional offices covering nine territories (UK & Ireland, Benelux, LATAM, Iberia, Italy, Central & Eastern Europe, US & Canada, APAC, Israel), supplemented by a managed security service provider (MSSP) channel that operates Radiflow deployments from third-party SOCs, and a broad integration partner ecosystem including Cisco, Palo Alto Networks, Fortinet, ServiceNow, Splunk, IBM QRadar, ST Engineering, Garland Technology, and Fujitsu. The platform supports compliance with NIS2, IEC 62443, NERC CIP, and NIST CSF frameworks, positioning the company in regulatory-driven segments where critical infrastructure operators face binding cybersecurity mandates. With solutions deployed at 20,000+ industrial sites worldwide, Radiflow operates with a lean 11-50 person team, relying on its partner network for scale and Sabanci Group for strategic anchor access to critical infrastructure customers.

Products and services

• iSID Industrial threat detection and monitoring system that passively monitors OT network traffic using DPI protocol-based analysis, automatically discovers and inventories assets, builds behavioral baselines, and detects anomalies and policy violations. Provides network visibility, vulnerability management, and alert management for OT/ICS environments.
• CIARA Data-driven OT risk assessment and management platform for industrial organizations. Uses ML-driven OT-BAS (Breach and Attack Simulation) engine that ingests thousands of data points on network, asset, locale, industry, adversary capabilities, and attack tactics to calculate per-zone/per-site/overall likelihood of attacks, determine impact on business processes, and produce ROI-optimized mitigation plans aligned with IEC 62443.
• iCEN Centralized security monitoring and risk management platform that provides a single pane of glass across all iSID installations. Enables multi-site operators and MSSPs to collect and share cyber data between iSID and CIARA, schedule and initiate risk assessments, consolidate alerts, and manage multi-customer deployments with client-based view permissions.
• Active Scanner Safe, active OT scanning tool that directly queries assets using native protocols to obtain deeper data such as modules, versions, and patch levels. Complements or replaces passive monitoring by iSID, supports hybrid operation mode, and does not require port mirroring.
• vSAP RF-2180 Smart Collector Cost-effective distributed hardware collector for remote OT sites that aggregates and tunnels mirrored network traffic to a central iSID instance. Uses Radiflow's patented compression algorithm (up to 1:10 ratio) and encrypted tunneling over transport networks to enable bandwidth-efficient WAN-friendly transfer.
• iSAP Smart Collector Smart collector that aggregates and tunnels real-time OT traffic from multiple operational units to a central iSID, reducing data volume by up to 90% for bandwidth-constrained remote sites.
