Government Secure Intranet
From Wikipedia, the free encyclopedia
Government Secure intranet (GSi) is a UK government wide area network, whose main purpose is to enable connected organisations to communicate electronically and securely at low protective marking levels.
Many UK government organisations use the GSi, using it to transfer files on a peer to peer basis between similarly accredited networks.
Organisations such as GCHQ, The Cabinet Office and SOCA use the GSi for secure purposes. Certain government organisations with high value material, such as MI5 and the SIS, use other networks with enhanced security to transfer this data.
