About

Scottish and Southern Electricity Networks is seeking a supplier to establish a framework agreement for the supply, delivery, installation, commissioning, maintenance and support of a cloud-based electronic key management cabinet solution that integrates with PAC access control and SSEN security management systems. SEN Distribution will replace 18 end-of-life electronic key cabinets and install a further 4 new cabinets, while SSEN Transmission requires deployment of a new solution across approximately 150 operational sites. The procurement aims to provide secure, auditable, tamper‑resistant key storage and management for vehicle, substation, key‑site and operational technology cabinet keys, with high availability (24x7x365) including failback/master key and break‑glass processes, central cloud management, component‑based architecture and out‑of‑the‑box integration capability with PAC, CCTV and IDS. The solution must align to recognised security standards (Cyber Essentials, Cyber Essentials Plus, ISO 27001/2, ISA/IEC 62443 2‑1, 2‑4, 3‑2 & 3‑3 and NIST 800‑53), support secure auditable key management and reporting, and be easy to operate and manage; suppliers are expected to demonstrate understanding and evidence of these requirements.
