Digital Signing as a Service


Adobe Acrobat Sign

Acrobat Sign provides the signing platform portal and ADACOM provides the Qualified Digital Certificates.

A secure, cloud-based digital signing solution

ADACOM verifies remotely natural persons’ identity and issues Qualified Certificates for Remote eSignature hosted in our Remote QSCDs. These certificates can then be linked to users' Acrobat Sign accounts, enabling them to apply legally binding signatures to digital documents.
