Adobe facilitates trusted and secure exchange of electronic documents and information by means of trust services that enable individuals, governments and enterprises around the world to run their businesses safely based on principles of Security, Availability, Authenticity, Integrity, Confidentiality, and Privacy.

 

Adobe Authorized Trust List (AATL)

The Adobe Approved Trust List (AATL) is the largest Trust Service for electronic documents in the world allowing millions of users to create digital signatures that are trusted whenever the signed document is opened in the ubiquitous Adobe Acrobat or Acrobat Reader software. Over 6 billion electronic and digital signature transactions are processed through Adobe Document Cloud solutions every year.

Acrobat and Acrobat Reader have been programmed to reach out to an online service run by Adobe to periodically download a list of trusted digital certificates from leading Trust Service Providers.

Digital signatures created with a Digital ID that has been issued under any of the trustworthy certificates published in the AATL will appear as trusted in Acrobat and Acrobat Reader. This enormously simplifies the validation of these signatures without requiring any specialized software or custom configuration.

Visit the Adobe Authorized Trust List web page to know more about the AATL program and view the list of partners that provide trusted AATL Digital IDs.

Adobe European Union Trust List (EUTL)

EU Trusted lists are essential elements in building trust among electronic market operators by allowing users to determine the qualified status and the status history of trust service providers and their services.

The Adobe European Union Trust List (EUTL) is a reduced version of the combined trusted lists from all EU Member States and EEA countries which includes the information specified in Article 1 of European Commission Implementing Decision (EU) 2015/1505.


Some Member States may include in their trusted lists information on non-qualified trust service providers, but these services are excluded from the Adobe EUTL. Some Member States may also include in their trusted lists information on nationally defined trust services of other types than those defined under Article 3(16) of EU Regulation n. 2014/910. As these services are not qualified according to EU Regulation n. 2014/910, they are excluded as well from the Adobe EUTL.

Acrobat and Acrobat Reader have been programmed to reach out to an online service run by Adobe to periodically download the list of trusted digital certificates from EU Qualified Trust Service Providers that meet the requirements specified in Article 1 of the Implementing Decision (EU) 2015/1505.

Digital signatures created with a Digital ID that has been issued under any of the trustworthy certificates published in the EUTL will appear as trusted in Acrobat and Acrobat Reader. This enormously simplifies the validation of these signatures without requiring any specialized software or custom configuration.

Adobe Certified Document Services (CDS)

Certified Document Services (CDS) is a Trust Service enabled by the Adobe Root Certificate Authority.

CDS enables document authors to sign PDF files, using standard digital certificates, which automatically validate when authors are using Adobe Acrobat or Acrobat Reader software with no additional client software or configuration required.

CDS is designed to enable organizations and individuals who publish high-value documents to large and disparate recipient groups to increase the assurance level that the document's integrity and authenticity are preserved. By adding a CDS signature to a PDF file, document authors can increase this assurance level without requiring recipients to deploy additional software or adopt complex configurations.

The Adobe CDS Certificate Policy establishes requirements for how CDS Certificate Authorities operate.

Visit the Certified Document Services web page to know more about the CDS Trust Program and view a list of partners that provide trusted CDS Digital IDs.
