Membership of The Congress of Unisys Users (CUU) is open to all those organisations within Europe who use products and services provided by the Unisys Corporation or who provide complementary services to Unisys clients.

The Congress represents users and suppliers of Unisys equipment and services across Europe and maintains close links with the supplier. Primarily, the Congress was formed to foster cooperation and contacts between members and to encourage the exchange of technical experience and ideas. This is achieved by means of Interest Group meetings, Forums, Conferences and publications. Unisys provides active co-operation at all levels in this process.
