A digital signature uses a secure digital key that identifies the author of a digital message or document. Digital certificates give customers confidence that signed documents come from a recognized source and have not been tampered with or altered.

Adobe Document Signing Certificates offered by Sectigo allow organizations to protect Adobe Acrobat documents with digital signatures. Certification comes from Adobe Certified Document Services (CDS) or certification authorities that are members of the Adobe Approved Trust List (AATL). The certification confirms that the subscriber has been verified by Adobe for compliance with its requirements and that the certificate is on secure hardware.
