ZertES-compliant qualified electronic signatures for Swiss businesses

Switzerland's law for electronic signatures, known as ZertES, recommends using qualified electronic signatures (QES) on all digitally signed documents to ensure better compliance and security. While a digital signature is usually sufficient, businesses operating in regulated industries such as banking, healthcare, or finance are required to use QES.

Zoho Sign makes the digital signing process secure and smooth with QES via Swisscom for businesses in Switzerland and operating across Europe.

QES are digital signatures that come with digital certificates that are uniquely issued to an individual after stringent identity verification procedures. They are considered the most secure way to digitally sign documents. Zoho Sign integrates with Swisscom Trust Services, one of the most trusted QTSPs in Switzerland, to provide QES for businesses in both Switzerland and the European Union. Digital signature certificates issued by Swisscom are compliant with both ZertES, the Swiss federal law governing use of digital signatures, and eIDAS, the EU regulation (910/2014) on the same.
