Certified Cloud Services List (CCSL) identified cloud services that have successfully completed the Information Security Registered Assessors Program (IRAP) assessment and had been certified by the Australian Signals Directorate (ASD).

Based on the Australian Government Information Security Manual it gave confidence to Australian government agencies to use such cloud services.

Macquarie Government was the first Australian cloud provider to be listed on the CCSL and was certified for both Protected (classified) and Official (unclassified) cloud services.

The CCSL program ended on the 27th of July 2020, but is still used as a reference, alongside the DTA Hosting Certification Framework, when choosing cloud providers.
