OG86 to IEC 62443…what’s really changing?

Series 3 - Episode 2!The landscape of industrial cybersecurity guidance in the UK is evolving, and many organisations are now navigating the transition from HSE’s OG86 guidance to the more comprehensive IEC 62443 standard.In this episode of Cyber Brews, we explore what that shift really means for engineers, operators, and organisations responsible for industrial control systems and operational technology.We discuss why OG86 existed, the role it played in protecting safety-related systems, and how the growing cyber threat landscape has driven the move toward IEC 62443’s broader, lifecycle-based approach to cybersecurity.Along the way, we unpack key differences between the two approaches, the expectations emerging from regulators, and some of the practical challenges organisations face when applying these concepts to real-world OT environments.So grab a brew and join us as we break down the journey from OG86 to IEC 62443 and what it means for the future of industrial cyber security!
