Certification Service Provider

CH Trusted List

Our services comply with the strict requirements and security standards set out in the ZertES regulations, as listed in the directory of recognised certification service providers (CSPs).

What is a Certification Service Provider?

A certification service provider (CSP) is a service provider that offers electronic identity and trust services in accordance with the ZertES Ordinance. This includes, among other things, digital signatures and seals, which are intended to ensure the integrity and confidentiality of electronic documents and transactions.

How is SIGN8 tested?

SIGN8 is regularly audited and recertified by an independent external auditor in accordance with ZertES. Internal audits are also carried out.

How do I benefit from this?

SIGN8 signs and seals the documents itself. This means your documents never reach a third party. In addition, you work in an audited environment through the audits.
