Coswin is a computerised maintenance management system (CMMS, GMAO) from the Siveco group. The vendor's website presents a range of Coswin software versions, with Coswin 8i among the products, and offers implementation and support services. Maintenance departments use such systems to plan work orders, manage equipment and organise preventive maintenance. The website does not state how the software is priced or whether it runs on customer servers or is offered as a hosted service.
Siveco Group SA has its headquarters at Montigny-le-Bretonneux in the Yvelines department of France, according to its own website, whose footer names Siveco Group SA. The site names no majority owner, so no foreign parent is named. The hosting location of Coswin customer data is not described. For a European organisation the vendor is a French company subject to EU data protection rules. The sovereignty question depends mainly on the deployment choice: software run on the organisation's own servers keeps maintenance data under its control, while a hosted service requires checking where the data is stored. Coswin is not published as open source.
