Certifications and memberships

Paragraph steht symbolisch für Zertifikationen

SwissSign is audited by KPMG Switzerland and is recognised as an official certification authority (CA). This recognition entitles SwissSign to issue qualified electronic and advanced certificates.

SwissSign is also a member of the CA/Browser Forum, the TeleTrusT European Bridge CA and the Adobe Approved Trust List and has been awarded the "swiss made software" label.


SwissSign AG has been a "recognised provider of certification services" in accordance with the Swiss Electronic Signature Act (ZertEs) for many years. This allows SwissSign to issue qualified certificates and products for qualified electronic signatures which enjoy great prestige under Swiss law.

For example, SwissSign issues the SuisseID. With its qualified certificate, a qualified electronic signature can be accorded the same status as a hand-written signature in accordance with the Swiss Code of Obligations. This recognition, however, also allows SwissSign to issue digital certificates to companies and organisations for electronic invoicing (ElDI-V) and archiving (OElDI) in accordance with Swiss law. The details are governed in the applicable Swiss legislation and implementation provisions.

This recognition does not cover other certificate products and services. The certifications associated with this recognition, however, guarantee a controlled level of quality for all certificates offered by SwissSign as well as compliance with the relevant international technical standards: e.g. l ISO 27001, ETSI TS 101456, ETSI TS 101862, ETSI TS 102023, ETSI TS 101861, SR943.03 (ZertES), SR943.032 (VZertES), SR943032:1:2005 (TAV).

CA/Browser Forum

The CA/Browser Forum is a group of certification authorities (CA) and manufacturers of operating systems, web browsers and other web applications. SwissSign has been a member since 2009.

The members of the CA/Browser Forum work together closely with the objective of increasing Internet security. They define and publish the standards and rules for the issuing and management of SSL certificates. This means that:

  • The root certificates of certification authorities (CAs) are integrated within web browser certificate stores – subject to the fulfilment of the baseline requirements, EV guidelines and network security demands.
  • Web browser manufacturers can specially indicate the Internet sites of trusted providers in the browser display.
  • Users can ultimately recognise secure Internet sites on the basis of a symbol (e.g. a padlock) or the colour highlighting of the accessed Internet address.

Adobe Approved Trust List

Thanks to the Adobe Approved Trust List (AATL) programme, users can create digital signatures which are classified as trusted upon the opening of signed documents in Acrobat or Reader from version 9.

In both Acrobat and Reader, a list of trusted digital root signatures is downloaded from an Adobe-hosted website every 30 days. A signature linked to a certificate on this list is classified as trusted.

The trusted root certificates are checked by Adobe in compliance with special technical requirements. These ensure high standards in the areas of identity verification and signature credentials. The certificates contain individual and official credentials as well as the credentials of accredited certification providers. SwissSign is a member of the programme and the highest level certificates (EV, SuisseID and organisation certificates) are listed in the AATL.
