Union Nationale des Mutualités Socialistes (UNMS) is a private establishment responsible for the management of a public service for the Belgian national health agency. The wide variety of formats and interconnections in such a diverse system made back office maintenance more and more complex. To meet their requirements, UNMS chose the Axway Synchrony integration platform. The benefits became quickly evident: flows became transit via one unique point, information is translated into formats required by partners, and all exchanges are monitored in real time. All these elements foster the integrity of data and the processing chain.
