Heimdal: sovereignty score and 8 European alternatives

Heimdal is a Danish cybersecurity company with an XDR (extended detection and response) platform. Its cloud-based suite has grown from antivirus and DNS-based threat detection to include firewall management, email security, remote desktop tools and a security operations centre. It is delivered on a subscription basis as a multi-tenant cloud platform, for organisations that want several layers of protection from a single vendor.

Heimdal is headquartered in Copenhagen, Denmark. Since 2020 it has been owned by Marlin Equity Partners, an investment firm based in Los Angeles. The ultimate parent is therefore in the United States, which is a CLOUD Act signal for European customers. The sources consulted do not state where Heimdal hosts customer data; a European organisation should therefore ask for the hosting region and the list of sub-processors. The software is proprietary and not open source.

Why digital sovereignty matters with Heimdal

Heimdal is headquartered in DK and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

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

Heimdal 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 Heimdal together with your other vendors and gives a total score, a heatmap and the main risk drivers.
