The product

Validation and sealing.
One neutral infrastructure.

Two products — one for verifying what was signed, one for applying seals that anyone can verify. Both built on independent infrastructure that no platform controls.

Document validation

Independent verification — no platform dependency.

Tindom validates electronically signed documents against the EU LOTL and Adobe AATL trust lists using a self-hosted engine — independent of the platform that created the signature. The result is structured evidence: the qualification level, the signer, the trust chain, and when it was verified — all without relying on a vendor's assurance.

Managed qualified seals for organizations

The same engine that independently verifies a signature is what verifies a seal — so the natural next step is helping organizations apply seals of their own.

Seal management is a service layer for organizations that need every document they issue to carry a qualified electronic seal — registered to them as a legal entity, and independently verifiable by any recipient. The seal certificate is issued by an accredited Qualified Trust Service Provider; Tindom operates the layer above it: applying the seal, managing the certificate's lifecycle, maintaining the audit trail, and integrating sealing into existing document workflows.

Tindom is not the certificate issuer and not a signing platform. It's the neutral operational layer between an organization and the trust infrastructure it needs but shouldn't have to run itself.

This is what we're building next. If your organization issues official documents that recipients must be able to trust and verify — in government, finance, or regulated industries — we'd like to talk.

Roadmap

What's coming

Today, Tindom validates PAdES signed documents. The roadmap expands to all major signature formats — XAdES, CAdES, JAdES — and further, to qualified electronic seals managed on behalf of government agencies and financial institutions. The goal is a single, neutral trust infrastructure for business transactions across Europe.
