SD Worx is a Belgian provider of HR, payroll and time solutions for European employers, from small and mid-sized businesses to large enterprises. Its offering covers payroll and reward, workforce management, core HR, HR analytics, talent management and training through the SD Worx Academy. The mysdworx app supports everyday HR processes. Customers can outsource all or part of their HR administration to SD Worx, which has a local presence in dozens of European countries.
SD Worx is a Belgian group; WorxInvest is its majority shareholder, and the group's offices are in Belgium. The sources consulted show no foreign parent company. They do not state where customer data is hosted, so this should be confirmed in the data processing agreement. The software is not open source. For a European organisation this means the service provider and its owner are established in the EU, while the hosting location and any sub-processors need to be settled contractually.
