The Public Services Network (PSN) is the UK government’s communications network allowing public sector organizations and their partners to connect and communicate.
Organizations connecting to PSN, whether service consumers or service providers must demonstrate that they have a suitable level of security to minimise the risk to other PSN users. In order to report and demonstrate the level of security a PSN compliance certificate is required.
To achieve PSN compliance an application process must be followed including completion of the Code of Connection and submission of a recent IT Health Check report for your PSN environment.
