Radiflow

Radiflow is an Israeli operational technology (OT) security vendor founded in 2009 by Ilan Barda, focused on protecting industrial control systems and critical infrastructure — manufacturing, power and renewables, oil and gas, water and wastewater, maritime, and building management systems. In May 2022, Sabanci Group, the Turkish industrial and financial conglomerate, acquired a 51% majority stake in Radiflow for $45 million through its Netherlands-based digital investment arm, with a plan to complete full acquisition by 2025; Radiflow continues to operate under its own brand and product line.

The company’s platform centers on iSID, a passive network monitoring and anomaly-detection engine purpose-built for ICS/SCADA protocols, paired with CIARA, a risk-scoring and simulation tool that models the financial and operational impact of specific attack scenarios against a plant’s actual asset inventory rather than generic vulnerability counts. iCEN provides central management across sites, and Smart Collector handles data acquisition from legacy equipment that can’t run modern agents.

Radiflow’s differentiator is CIARA’s business-impact framing: instead of just flagging vulnerabilities, it estimates what a given attack path would cost a specific facility to remediate and lose in downtime, which OT security teams use to prioritize patching decisions against operational risk rather than CVSS scores alone. The company is a long-established, comparatively small player (around 35 employees) that has been through multiple ownership changes, most recently coming under a strategic industrial parent rather than a financial sponsor.
