MI5 – The Security Service

At MI5 we safeguard the UK against threats to national security including terrorism, espionage, cyber and sabotage. We do this through investigating suspect individuals and organisations to obtain, collate, analyse and assess intelligence relating to those threats.

We also act to counter the sources of threats, as well as working to reduce any government or infrastructure vulnerabilities.

MI5 offers varied and rewarding careers in a supportive and encouraging environment that puts the emphasis on teamwork. We also place great importance on our staff maintaining a healthy work-life balance. Whichever career path you choose, you will be working to help keep the country safe.
