ENCS is a non-profit membership organisation that works with critical infrastructure groups and security specialists across Europe. Founded in 2012, it supports members through applied research, technical security requirements, testing, education and training.
Its network includes transmission system operators, distribution system operators and regulators. By joining as an Information & Knowledge Sharing member, SSEN Transmission is entering a forum focused on common cybersecurity issues across energy networks, rather than a bilateral arrangement with a single partner.
That matters because electricity operators increasingly face similar challenges across borders, especially in the operational technology environments that underpin power networks. Utilities must also respond to a regulatory climate in the UK and EU that places greater…
