TL;DR: Signature assurance under eIDAS depends on how well identity is verified and keys are protected, GlobalSign argues. Document signing then carries different evidentiary weight, so legal teams need to match the signature level to the dispute risk.
Editorial analysis by NHI Mgmt Group, based on content published by GlobalSign: “eIDAS y los usos de la firma electrónica: Comparación de los tres niveles de garantía”.
Key questions
Q: Why do e-signatures still need identity governance if they are legally valid?
A: Legal validity does not guarantee operational trust.
Q: What are the main failure points in advanced and qualified signature workflows?
A: The most common failure points are weak identity verification, poor certificate lifecycle management, insecure private key handling, and unclear trust service oversight.
Q: When should teams use qualified electronic signatures instead of standard e-signatures?
A: Use qualified signatures when legal recognition, cross-border validity, or higher evidentiary strength is required.
Practitioner guidance
- Define signature assurance tiers by use case Classify documents by legal risk, dispute likelihood, and cross-border recognition needs, then map each class to SES, AdES, or QES accordingly.
- Strengthen certificate and key governance Treat certificate issuance, private key protection, and revocation as identity controls, with ownership and lifecycle review built into the approval process.
- Use qualified signatures for high-exposure workflows Reserve QES for contracts, filings, and other transactions where explicit legal equivalence to a handwritten signature materially changes the risk profile.
Bottom line: eIDAS distinguishes signature levels by assurance, not by appearance, and that distinction determines evidentiary strength.

Identity assurance, not document handling, is the real control boundary in eIDAS. The article makes clear that the security value of a signature comes from signer verification and key custody, not from the act of placing a mark on a document. That means legal operations and identity governance cannot be separated when signatures carry regulatory or financial weight. Practitioners should treat signature assurance as part of the identity stack, not as a standalone workflow choice.
A question worth separating out:
Q: How should security and legal teams decide between SES, AdES, and QES?
A: They should base the decision on the document’s risk, the expected burden of proof, and whether the signature needs explicit legal equivalence across the EU. Low-risk acknowledgements can use simpler methods, while contracts, filings, and high-value agreements generally need stronger identity assurance.
