Qualified Electronic Seal
Accredited conformity assessment of qualified electronic seal services under the eIDAS Regulation and applicable ETSI standards.
Who needs this — and why
Trust service providers issuing qualified electronic seals need accredited conformity assessment before the service can be listed as qualified under eIDAS.
Qualified electronic seals allow legal entities to prove the origin and integrity of electronic documents. They are widely used by public authorities, financial institutions, healthcare providers and organisations issuing official records, invoices or automated business documents.
Unlike an electronic signature, which identifies a natural person, a qualified electronic seal represents a legal person. Trust therefore depends on the security of the issuing service, its certificate management and the controls protecting the seal throughout its lifecycle.
Because every trust service differs in architecture and operational scope, every assessment begins by defining the appropriate scope.
Assessment of qualified electronic seals
Qualified electronic seals depend on secure certificate management, trusted operational processes and effective cryptographic controls. Our auditors combine accredited assessment with practical security expertise to verify that the service consistently satisfies the requirements for qualified trust services.
What the certification covers
Our assessment covers the complete lifecycle of a qualified electronic seal service, from certificate issuance and key management to seal creation, validation and ongoing operation. We examine how organisational seals are issued and protected, how cryptographic keys are managed and how the service preserves the integrity and authenticity of sealed documents.
The assessment also includes the wider governance and security framework supporting the service, including certification practices, operational procedures, incident management, change management and supporting technical controls. 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 seal 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 35–40)
- 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 seal 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.
