Governikus DATA Sign
The signature and seal platform

Back to products

The signature and sealing platform from DATA Sign combines all functions relating to electronic signing and sealing. From the signing or sealing process to its authenticity/validity check (validation), the entire process is combined for you in one tool.

Regardless of whether you want to provide a large number of documents with your seal/signature, whether an advanced or qualified signature/seal is required and whether you want to use a remote signature provider or a signature card with reader: with DATA Sign you have all requirements covered with one software.

DATA Sign also offers many other functions and is constantly being further developed by us. For example, you can use the User Self Service to manage your key material or open an account with remote signature providers.

DATA Sign is part of the IT Planning Council's Governikus application.
