Exchanging classified information internationally

The UK National Security Authority (UK NSA) is part of the Government Security Group (GSG) responsible for the protection of classified information received from international partners. It sets policies and guidance for exchanging classified information internationally.

Here you can find information about sharing UK classified information internationally, the standards and processes that are required, and further information on the UK’s obligations to protect the classified information received from other nations and International Organisations (such as NATO and the European Space Agency).
