Validates signatures, seals and timestamps
Checks the validity of signatures, seals, and timestamps
Complies with EU and national regulations and best business practices
Is your gatekeeper for not accepting erroneous signatures, seals, and timestamps to avoid possible future legal issues


When relying on signatures, seals, or timestamps, it is important that they be valid. You want to ensure that your signature is applied correctly and as intended. When you receive a document with one or more signatures or seals, you want to ensure that these are valid before you sign, process, or archive these documents.

With Comfact Validation, signatures, seals, and timestamps are validated in order to confirm that they are correct and advanced or qualified.

If a signature, seal, or timestamp is incorrect (not valid) or it is not advanced or qualified, legal problems can arise. Therefore, signatures, seals, and timestamps should be validated before acceptance according to a set baseline. It is also possible to include specific policy requirements stating the minimum compliance.


The validation of signatures, seals, and timestamps is used in different ways. When using Comfact Signature, Seal, or Timestamp, one of the last steps is to check with Comfact Validation. If a document to be signed already contains signatures, seals or timestamps from another service, these are validated before signing, sealing, or timestamping.

Documents that are signed, sealed, or timestamped should be validated before they are stored and accepted in an E-archive or other application by an organization.

If incorrectly signed, sealed, or timestamped documents are accepted by an organization, severe problems could arise in the future as they can be regarded as null and void. This is why Comfact Validation is your gatekeeper of your legally important documents.

Comfact Validation can be used from applications with our API. A sealed validation report is returned together with the validation results
Comfact Validation can be used manually from this web page without a validation report sealed by Comfact AB

In order to avoid external exposure of the document contents, the Comfact Client can be used. This makes use of our API and does not transfer the actual document content externally which remains on the internal network
