Documents are validated on Tindom's own infrastructure and are never stored after validation is complete.

How it works

01 — Upload

Submit a signed document

Drop a signed PDF into the validator above. 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 structured validation attestation

Receive a structured Tindom Validation Attestation documenting the validation result — independent evidence you can use in legal, compliance, and 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.
