Ascertia: sovereignty score and 8 European alternatives

Ascertia develops software for public key infrastructure (PKI), digital signatures and trust services. Its main products are ADSS Server, a framework for signing, verification, timestamping and certificate management for trust service providers, and SigningHub, an e-signature and document approval application. Customers can choose a cloud service or an on-premise deployment, according to the company's website. Ascertia Limited is based in London and also operates in the UAE and Pakistan, and its customers include central banks, government agencies and large enterprises.

In January 2023 InfoCert S.p.A., part of the Italian Tinexta group, announced an agreement to acquire 65% of Ascertia. Ownership therefore sits in Italy, which is the relevant foreign-parent fact for a European buyer, while the operating company is a UK limited company. The website does not state where its cloud services are hosted. For European organisations, UK incorporation means that data transfer and contract terms should be checked, and the on-premise option may be the more direct route when data must stay in the EU.

Why digital sovereignty matters with Ascertia

Ascertia 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. The ultimate owner is based in IT, also within Europe.

Ascertia 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.

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