Compatibility: Dissemination of the SwissSign certificates

To ensure your customers and partners can verify the certificates issued by SwissSign and can trust these, browsers and operating systems need to have installed the so-called root certificate of SwissSign CA.

The following overview shows that all common operating systems and approx. 99% of the used browsers have stored the root certificate of SwissSign and that this does not have to be installed manually. SwissSign is member of the CA Browser Forum and will follow all standards within this Browser Forum. SwissSign cannot guarantee that the certificate will still be trusted during the complete lifetime if a browser or application supplier will not follow this standard anymore.
