The product

Validate what was signed.
Independent of where it was signed.

A signed document means nothing if you can't verify it independently. Tindom provides that verification — against the standards that courts and regulators recognize.

How it works

01 — Upload

Submit a signed document

Send a signed PDF to Tindom. The document is processed transiently — never stored after validation is complete.

02 — Validate

Independent verification

Tindom checks the signature against the EU LOTL and Adobe AATL trust lists using a self-hosted validation engine — no signing platform involved.

03 — Report

A court-ready attestation

Receive a structured Tindom Validation Attestation documenting the validation result — usable as evidence in legal, compliance, or regulatory contexts.

Standards

Built on open standards

Tindom runs on the EU's reference implementation for electronic signature validation — eIDAS / ETSI TS 119 102-2. Trust list synchronization is automated. No platform dependencies. No black boxes.

EU LOTL

European List of Trusted Lists

The authoritative source for Qualified Trust Service Providers across all EU member states. Updated continuously and synchronized automatically into Tindom's validation engine.

Adobe AATL

Adobe Approved Trust List

The global trust list for digital signatures recognized by Adobe Acrobat — covering certification authorities outside the EU regulatory framework.

Roadmap

What's coming

Today, Tindom validates PAdES signed documents. The roadmap expands to all major signature formats — XAdES, CAdES, JAdES — and further, to provisioned Qualified Electronic Stamps for government agencies and financial institutions. The goal is a single, neutral trust infrastructure for business transactions across Europe.
