Zelt: sovereignty score and 8 European alternatives

Zelt is a UK cloud platform for HR and payroll, aimed at employers in the United Kingdom. It covers employee records, payroll, benefits, leave and time off, performance management, and expense and invoice management, and it includes management of IT devices and apps. Users reach the service through a web interface and through iOS and Android apps. The company says its payroll functions automate submissions to HMRC, the UK tax authority.

The supplier is ZELT LTD, a UK company named in public procurement listings. The website describes Zelt as UK-based and states that data is stored and processed in the United Kingdom. For a European organisation, the main points are UK jurisdiction, data storage outside the EU and EEA, and the need to check the contract terms and sub-processors before use.

Why digital sovereignty matters with Zelt

Zelt is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Zelt hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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