InterSystems: sovereignty score and 8 European alternatives

InterSystems supplies data platforms for sectors including healthcare. InterSystems IRIS for Health is a development platform for healthcare applications, with support for standards such as HL7 FHIR, interoperability services and analytics in a single engine. HealthShare is a suite of solutions for capturing, sharing and analysing health information from multiple sources, including a Unified Care Record and Health Insight. Organisations run it in the cloud or on-premises; InterSystems also offers managed services such as FHIR Services and IRIS Cloud Services.

InterSystems is a privately held company headquartered in the United States (Boston, Massachusetts), so US legislation such as the CLOUD Act can apply. The company names AWS, Microsoft Azure and Google Cloud as cloud platforms, so where your data sits depends on the cloud and region you choose. The software is proprietary and not open source. For sensitive patient data, check the chosen region and the contractual terms.

Why digital sovereignty matters with InterSystems

InterSystems is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Data is hosted exclusively in the EU, so InterSystems scores best on data residency.

InterSystems is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs InterSystems together with your other vendors and gives a total score, a heatmap and the main risk drivers.
