EcholoN is a modular service management platform from mIT solutions GmbH in Borstel-Hohenraden near Hamburg, a company that has worked on this software since 1994. Organisations use it to digitise processes without programming: ticketing and service requests, ITIL-based IT service management with incident, problem and change handling, SLAs and a CMDB, as well as field service, maintenance, quality and compliance. It includes workflows, role-based self-service portals, connections to ERP, SAP and CRM systems, and reporting. The software comes in several editions and can be extended with a licence key.
EcholoN runs on-premises, in the cloud as SaaS, or as a managed service. mIT solutions describes itself as a family business with a German base and reports no foreign owner. The vendor does not state on its website where the cloud service is hosted, so ask for it. An on-premises installation keeps data fully under your own control and within European jurisdiction.
