OT Cyber Security

In 2020, a large utilities company was looking to improve their cyber security posture across 100+ sites. This large-scale project involved both site remediation and the supply and commissioning of a Cyber Intrusion Detection System. In this video, Simon Hoy (Engineering Manager for Vysiion) talks us through the challenges the utility company faced and how we have helped them upgrade their legacy networks, enable real-time passive network monitoring and improve their cyber posture, in line with the NIS directive.
