What is AATL ?

AATL stands for Adobe Approved Trust List, a program that allows users worldwide to create trusted digital signatures whenever a signed document is opened in Adobe® Acrobat® or Reader® software. GlobalSign is a member of this list. AATL was introduced in Adobe Reader/Acrobat v9.0. Therefore, GlobalSign’s AATL Document Signing Certificates are compatible with Adobe Version. 9+ Prior to AATL, Adobe offered the Certificate Document Services (CDS) program. The Adobe CDS program was launched in 2005 with five member CAs (GlobalSign being one of them). CDS has been phased out in preference of AATL. For more information on how AATL compares to CDS, please see our blog post. Additional information on Adobe's Approved Trust List (AATL) can be found on Adobe’s website here.
