Enhancing Operational Resilience for Digital Industry.
Digital transformation between physical machines and computer systems is accelerating IT and OT convergence, increasing automation and network connectivity that is leading to excessive cyber risk. With deep roots in AI-driven cyber-physical security research and intrusion detection, at Exalens, we are enhancing operational resilience for cyber-physical systems at the OT edge. With the world's first cyber-physical security AI, which combines the capabilities of a human cybersecurity analyst with an OT engineer's understanding of physical system behaviour and processes, Exalens enables organisations to intelligently respond to cyber and physical system incidents in seconds - maximising system uptime and safety.
