MI5 – The Security Service
MI5's mission is to keep the country safe. For more than a century we have worked to
protect our people from danger whether it be from terrorism or damaging espionage by hostile states.
Careers at MI5
A career at MI5 is like no other. Not only is it rewarding and
unique, but the variety is unlike anywhere else. Our employees have significant
autonomy to manage their own careers and the opportunity to change jobs or business
areas every two to three years. It wouldn’t be unusual for someone to work in
counter-terrorism, recruitment, counter-espionage and corporate communications
within their first few roles. This variety together with our supportive and flexible
working environment means most people who join MI5 stay for a substantial part of
their careers.
