To protect the UK from a range of national security and overseas threats, keeping its citizens safe.
MI5, the UK's domestic intelligence service, plays a crucial role in protecting the nation from a range of security threats. By focusing on counterterrorism, espionage, and cyber threats, MI5 works to safeguard the public and support law enforcement agencies. Its work, largely behind the scenes, is pivotal in ensuring national security.
Founded in 1909, MI5 originally focused on countering German espionage during World War I. Over time, its role expanded to address evolving threats, such as the rise in domestic terrorism and the increasing significance of cyber threats. This evolution reflects MI5's ability to stay ahead of emerging security challenges, adjusting its strategy and operations as needed.
As technology and global threats change, MI5's approach continues to evolve, ensuring the UK's security remains a top priority. With its deep expertise and ongoing adaption, MI5 is a major key player in protecting national interests and responding to complex security dynamics.
