Key differences at a glance

All eIDAS Signature Levels

ValidSign supports Simple (SES), Advanced (AES), and Qualified Electronic Signatures (QES) for full eIDAS compliance. Ondertekenen.nl primarily supports SES signatures, which may not meet requirements for all use cases.

Dutch-Built Platform vs International Technology

ValidSign is developed and hosted entirely in the Netherlands, giving you full control over data sovereignty. Ondertekenen.nl, originally Dutch, is now under American ownership and built on international technology, which may raise questions about data processing for compliance-sensitive organisations.

200+ Enterprise Integrations

ValidSign integrates natively with Salesforce, SharePoint, SAP, AFAS, Topdesk, and 200+ platforms. Both platforms offer API access, but ValidSign provides significantly more out-of-the-box connectors for Dutch business software.
