Security Service (MI5)

MI5, also known as Security Service, is the UK's primary agency responsible for protecting national security. Its main role is to detect, prevent, and investigate threats such as terrorism, espionage, and sabotage. MI5 works covertly, gathering intelligence to identify risks before they materialize, and collaborates with other agencies and governments. It operates within legal and constitutional frameworks, ensuring the safety of citizens and critical infrastructure without infringing on civil liberties. Its efforts help maintain the safety and stability of the UK in an increasingly complex security environment.
