SIS works secretly overseas to make the UK safer and more
We obtain secret foreign intelligence to inform Government
decisions. We disrupt terrorism and nuclear proliferation, and our

with the Government. The secrecy of our operations, and the

SIS is a modern organisation with sophisticated technology and a
diverse workforce - all dedicated to protecting the UK, and
contributing to a more prosperous and peaceful world.
