Menu names and licence requirements change over time: check the current Microsoft or Google documentation.

Microsoft 365 · Entra ID · Intune

  • Add and verify your domain in Microsoft 365 and set it as default for all users.

Evidence to prepareVaurely guidance

Aramco’s CCC program requires recent, time-stamped and clearly labelled evidence for each control. The list below is what we recommend preparing; the audit firm decides what it accepts.

  • Domain configuration screenshot; the e-mail addresses used in your Aramco correspondence.

Common mistakesVaurely guidance

  • Sales staff or subcontractors corresponding with Aramco from personal Gmail addresses.
