Mission - National Security Bureau

The National Security Bureau (BBN) is a body providing aid and support to the President of the Republic of Poland in executing security and defence tasks.

It fulfils the tasks entrusted by the President related to the security and defence matters. They result from the role of the President as the supreme representative of the Republic of Poland and the guarantor of the continuity of the State authority, responsible for ensuring observance of the Constitution, safeguarding sovereignty and security of the State as well as inviolability and integrity of its territory. The Bureau’s tasks result also from the constitutional function of the President who is the Supreme Commander of the Armed Forces.

The competences of the President of the Republic of Poland related to the command over the Armed Forces are described in detail in the Act of 21 November 1967 on the Universal Duty to Defend the Republic of Poland.
