We are responsible for providing leadership, operational support and oversight of the security management system. We ensure security for staff and eligible dependants and enable the safest and most efficient conduct of the programmes and activities of the United Nations System.
UNDSS is an element of the United Nations Security Management System (UNSMS), which is an UN system-wide approach to security. It encompasses policies, guidelines, processes, and security personnel aimed at managing security risks to the UN system in order to enable UN system activities worldwide. The UNSMS is composed of all UN system organizations grouped under the IASMN.

Where we work

You may know us from the uniformed security officers present in all UN HQs, commissions and tribunals, but UNDSS is also a network of security coordinators and advisors deployed wherever UN programmes are implemented. UNDSS maintains offices in more than 100 countries. Our deepest presences are in the worst security environments, to ensure that vulnerable populations can have the support they need.
UN Staff members are responsible for their own security and safety and must adhere to all laws of the host country. Wherever the UN has presence, UNDSS maintains a variety of tools and training to maximize the safety and security of staff.

"Protecting UN Personnel while facilitating our operations remains our top priority"
