FAQs
Our answers to the most frequently asked questions
Are Certifaction's eSignatures legally valid?
Yes. Our eSignatures are legally valid and support all major global standards (incl. eIDAS, ZertES, UETA, ESIGN).
In addition, you can choose the signature type that suits you best: from the cost-effective simple eSignature to the qualified eSignature (QES).
What is the Zero Document Knowledge technology and what are the advantages?
Unlike most competing providers, Certifaction offers the option of signing documents without ever seeing their content. The documents are processed locally on the customer side and encrypted when using the web app.
In the case of API integration, a local gateway takes over the encryption. In the event of a hack, the file would therefore be encrypted and unreadable. We also ensure that the documents are stored on ISO 27001-certified servers in Switzerland or an EU country.
Is there a white-labeled version of Certifaction?
Yes, Certifaction offers a customised white label option for partners. This enables the seamless integration of own products such as eIDs and certificates. The white label solution gives partners complete control over the platform. As an integration partner, we help open up new revenue streams and maximise business potential by providing tailored solutions for individual needs.
How much integration work is involved?
The Certifaction WebApp can be used immediately in the browser. The eSignature solution can also be integrated quickly via an API connection. Alternatively, the solution can be used as a white label product with full personalisation. Depending on the requirements, this is ready within a few weeks.
Why should I choose Certification over an on-premises solution?
What makes Certification stand out from the competition?
Certifaction is characterised by its innovative technology and clear focus on partnerships. Our customers value us as a trustworthy European partner that not only offers close cooperation and the highest security standards, but also enables the integration of its own products through white label solutions.
