Disig: sovereignty score and 8 European alternatives

Disig is a Slovak company based in Bratislava that provides qualified electronic signatures, qualified time-stamps, long-term archiving and public-key infrastructure (PKI) software. Its product range includes desktop and web signing tools, a mobile signing option that works with an eID card instead of a card reader, bulk signing for invoices and document bundles, a PDF signer, a validation authority and a time-stamping service. The company also supplies server products for enterprise customers, and offers a qualified signing portal for Windows, Linux and macOS.

Disig a.s. has its seat in Bratislava and presents itself as a Slovak provider of eIDAS trust services and NIS2-related security services. The website does not name its shareholders, so no foreign parent is named. It does not say where its services are hosted. For a European organisation, Disig offers a domestic signature and PKI option within EU trust-service rules. Some components are published on a dedicated open-source subdomain, but the company does not present itself as an open-source product.

Why digital sovereignty matters with Disig

Disig is headquartered in SK and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

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

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