UNDSS was formally established on 1 January 2005 to ensure the maximum security for staff and eligible dependents as well as enable the safest and most efficient conduct of the programmes and activities of the United Nations System.

For the first half-century of its existence, the United Nations felt protected by its flag and the reality that it was a neutral, benevolent actor in world events. In the early 1990s, there was a rise in the number of deaths and injuries of staff members as a result of malicious acts. Regrettably, the security environment for the United Nations changed and became more threatening. In addition, the mandates of the United Nations evolved, resulting in a larger number of United Nations staff members, notably from the humanitarian agencies, being deployed on potentially hazardous missions. At the same time, peacekeeping missions were being established in areas at war or in situations of high risk. Increasingly, humanitarian staff were deployed alongside peacekeeping military units in integrated multidisciplinary missions.
