About the session

Chair: Mike St John Green, Independent Security Consultant, IET Cyber Security Network.

Speaker: Ivan Zhekov, OT Cyber security Specialist, TXOne Networks


The pace at which AI enables attackers to identify and exploit vulnerabilities is outstripping the ability of most organisations to respond. This session makes the case for resilience as the governing principle of OT security. Not as a fallback, but as the foundation for risk management in industrial environments where patching cycles can't keep up with the threat landscape. Drawing on nine years of dedicated OT security research and innovation, TXOne Networks presents a practical layered defence approach in a story format covering (legacy) asset lifecycle protection and extension, risk prioritisation in operational context, virtual patching, ad-hoc security inspection and more - and demonstrates how industrial organisations can maintain a strong security posture even as the threats they face continue to evolve at machine speed.
