In a world full of increasing conflicts, rely on Swiss values such as quality and reliability for your digital certificates with our Managed PKI for public or private certificates of all kinds.
Certificate Lifecycle Management: Do you have your PKI under control?
In a few years, you will have to replace your SSL/TLS certificates at least eight times a year and switch to post-quantum cryptography. For automation and crypto-agility – with the highest level of compliance - use the Certificate Lifecycle Management from SwissSign, powered by Evertrust.
Digital signatures: high expectations for control and integration?
Digital signatures and seals need the highest credibility and must be precisely adapted to your systems – this is what our unique on-premise solution delivers, with full control over your data.
Digital Identities: Do you use paper for identification and credentials?
Issuing digital proof of membership, creditworthiness, and more, and verifying it reliably and quickly is the next step in the digital transformation of your organisation.
E-signatures, seals and time stamps: how processes in public administration can be designed simply, seamlessly with respect to media used and, above all, securely and legally compliant.

47 days TLS/SSL certificates and 10 days domain validation from 2029
On April 4, 2025, the CA/Browser Forum made a profound decision: the allowed validity period for SSL/TLS certificates and domain validations will be gradually reduced over the coming years. Roadmap and tips for preparation in our blog.
Client Authentication in SSL/TLS certificates no longer supported from 2026
What you need to do now
As of June 2026, the ‘Client Authentication’ purpose may no longer be entered in public SSL/TLS certificates, otherwise they will no longer be considered trustworthy by Google Chrome. Check in good time whether and to what extent you are using your SSL/TLS certificates in this way and what alternatives are available for your encryption – background information and recommendations from SwissSign.
