Qualified Electronic Signature
Accredited conformity assessment of qualified electronic signature services under the eIDAS Regulation and applicable ETSI standards.
Who needs this — and why
Qualified status for an electronic signature service is granted by a supervisory body, but it rests on conformity assessment: an accredited confirmation, independent of the provider, that the service conforms to eIDAS.
Qualified electronic signatures are used wherever organisations need documents to carry the same legal effect as handwritten signatures — from financial services and public administration to healthcare, legal services and cross-border business transactions.
Because trust in a qualified signature depends on the trust service provider behind it, the assessment extends beyond certificate issuance to the processes, infrastructure and controls supporting the entire service.
Every trust service is different in architecture, operational model and scope. The assessment therefore begins by defining the appropriate scope before any conformity activities take place.
Assessment at qualified signature level
Qualified signature services depend on far more than secure certificate issuance. Our auditors combine accredited assessment with practical security expertise to verify that certification practices, key management and operational controls consistently satisfy the requirements for qualified trust services.
What the certification covers
Our assessment covers the complete lifecycle of a qualified electronic signature service, from identity verification and certificate issuance to key management, signature creation, revocation and ongoing service operation. We examine how qualified certificates are issued, protected and managed, together with the controls supporting their integrity, availability and trustworthiness.
The assessment also includes the wider governance and security framework supporting the service, including certification practices, incident management, operational procedures, cryptographic controls and change management. Rather than reviewing individual controls in isolation, we evaluate how the service functions as a whole and whether objective evidence demonstrates that technical and organisational controls operate consistently in practice.
Standards & articles
Qualified electronic signature services are assessed against the applicable requirements of the eIDAS Regulation and its supporting ETSI standards.
This may include:
- Regulation (EU) No 910/2014 (Articles 28–34)
- ETSI EN 319 411-2
- ETSI EN 319 421
- ETSI EN 319 401
The exact assessment scope depends on the qualified trust service provided and is agreed with you during scoping, before the assessment begins.

Request an assessment
If you are launching a qualified electronic signature service, preparing for supervisory assessment or reviewing an existing qualified service, we can help define the assessment scope and explain what evidence will be required before the conformity assessment begins.
Your first conversation will be with an experienced eIDAS auditor who will discuss your service, applicable standards and the most appropriate assessment path.
