With Zynyo, your organisation provides a high quality service at low cost.

Zynyo is the ideal signing service partner for advanced and qualified digital signatures. As a Zynyo partner, you can offer advanced and/or qualified digital signing to your clients.

With Zynyo, your organization offers high quality services at low cost. In addition, Zynyo enables you to comply with current legislation and regulations (eIDAS, BW, Telecommunications Act, Pades, Xades) at all times. Zynyo also offers a variety of authentication methods, ensuring that the desired level of reliability is available for every signing process.

Watch out! EU PKI certificate mandatory!

According to European legislation (eIDAS), qualified and advanced electronic signatures must use PKI certificates issued in the European Union. Pay attention to this when choosing your signing service partner.

Zynyo has Dutch PKI certificates and therefore complies with the eIDAS regulation.

Zynyo has a Dutch PKI certificate which is required by European legislation for qualified and advanced electronic signatures. We agree fixed tariffs with you for the use of the signing services and our support department will help you quickly and adequately in the event of emergencies or normal user questions.

Integrate digital signing

Zynyo makes it easy to integrate your developed software with our signing services, providing your customers with legally valid digital signatures. Communication with our platform takes place via your own interfaces. This enables your clients to create advanced and/or qualified digital signatures from your software.

Expanding your service package

Zynyo offers Independent Software Vendors and other standard software providers the opportunity to extend your service package to include a signature service for advanced & qualified signatures. We can even integrate this into the applications you already offer. In this case we set up our signing service specifically for you so that your customers can easily work with it.

Expand your signing services

Zynyo makes it possible to link signing software you have developed to our platform so that your clients can have advanced and/or qualified digital signatures. You can then sign with Zynyo's organisation-specific PKI certificate, with your own organisation-specific PKI certificate or with the personal PKI certificates of your clients.
