MI5 deals with very sensitive information. Lives may be put at risk if sensitive information is disclosed carelessly. This makes it vital to manage information properly and release it only when absolutely necessary.

Section 1 of the Official Secrets Act 1989 prohibits our current and former staff from making unauthorised disclosures of information concerning security or intelligence that they acquired while working for MI5. We can only pass on information as is necessary for purposes of protecting national security.

The Official Secrets Act does not prohibit disclosures of unimportant matters. However, we advise our staff to be aware of the sensitivities and potential risks when discussing their involvement with or knowledge of MI5.

There’s no such thing as "a typical MI5 officer". 

We seek to recruit from all areas of the UK and all sections of society. Our staff members come from a wide range of backgrounds and cultures, reflecting the diversity of the communities in the UK that we serve.

MI5 is an equal opportunities employer. 43% of our staff are women and just over half of our staff are under the age of 40. An increasing number of staff members (currently around 9%) are from black or ethnic minority backgrounds, and 4% have a disability.
