Our Vision

Security for the UN, for a better world.

Understanding UN Security

The United Nations Security Management System (UNSMS) enables the activities of UNSMS organizations within acceptable levels of security risk. The UNSMS unites over 50 member organizations, with a primary objective of facilitating the operations of these entities while maintaining an acceptable level of security. Fifteen of these members serve as key decision-makers within the Inter-Agency Security Management Network (IASMN), which is an integral part of the UNSMS. Within this framework, the UNSMS plays a pivotal role in guiding, supporting, and acting as recipients of the UN Department of Safety and Security (UNDSS) services.

Where We Are

UNDSS is where UN operates in 131 countries.
Security is crucial to all UN programmes, so UNDSS works wherever the UN has a footprint. In addition, UNDSS personnel are deployed on surge missions where necessary.
