RADiFlow
An OT cyber security company that has unique tools to protect and manage digital OT assets for the long term
About RADiFlow
RADiFlow operates as a specialized provider of cybersecurity solutions meticulously designed for Operational Technology (OT) and Industrial Control Systems (ICS) networks. The company was established in 2009 by Ilan Barda and Rafi Horev. Ilan Barda, the current CEO, brings two decades of executive experience in the security and telecom sectors, including service in the Information Security division of the Israeli Defense Forces and a tenure as CEO of a Siemens/Nokia Siemens Networks subsidiary. This deep background in secure communications equipment directly informs RADiFlow's focus on protecting critical infrastructure.
The firm's business is centered on safeguarding critical infrastructure sectors such as power and renewable energy, manufacturing, oil and gas, water treatment, and transportation. RADiFlow addresses the growing cyber threats to these environments, which can disrupt essential services and lead to significant financial losses. Revenue is generated through the sale of its software solutions and services, either directly to major industrial enterprises and utilities or through a network of channel partners and as integrated components within the offerings of global automation vendors.
A significant milestone in RADiFlow's history was its acquisition by the Turkish conglomerate Sabancı Group in a two-phase process that began in April 2022. Sabancı acquired an initial 51% stake for approximately $45 million, with plans to purchase 100% of the company by 2025. This acquisition provides RADiFlow with substantial industrial backing to further enhance its product development and market reach. Prior to this, the company had secured $18 million in a 2018 funding round led by ST Engineering Ventures.
The company's product suite offers a full lifecycle of OT security. Key offerings include the CIARA industrial risk assessment and management platform, which allows clients to simulate breaches and prioritize security investments based on business impact. The iSID threat detection and monitoring solution provides passive network visibility and real-time anomaly detection without disrupting operations. These products are designed to be non-intrusive and help organizations comply with industry standards such as NIS2 and IEC 62443. The platform can be deployed on-premise or managed by a security service provider, and it integrates with other security tools like SIEM and SOAR systems.
