About MI5

MI5 is responsible for countering threats to national security, including terrorism, espionage, cyber threats and the proliferation of weapons of mass destruction. MI5 has played a vital and secret role in countering the activities of spies and terrorists for over a century. Since the late 1990s we have been releasing historical files to the National Archives Link to external website.. These files provide an insight into the work of MI5 and a behind-the-scenes look at famous spy cases from the 20th century.

Don’t forget to cite Bright Network on your MI5 application form, they’re keen to hear from our members.
