What we do

Corruption in defence and security heightens conflict risks, wastes public resources, and exacerbates human insecurity. Events such as the collapse of the Afghan security forces and fall of Afghanistan, Russia’s war in Ukraine, and a spate of coups across Africa, have brought these linkages into sharp relief, and shone a glaring light on the need for change.

Transparency International Defence & Security is a leading centre of excellence and advocacy on these issues. Part of the global Transparency International Movement, we are working to bring corruption in defence and security out of the shadows. We champion transparency, and mobilise national and international action to build integrity and better security for all.

We work to strengthen defence integrity in a number of countries and contexts worldwide. Find out more about where we work.
