I perform best practice audits of customers’ Conditional Access (CA) policies on a regular basis. If you have ever done this, you will quickly notice that it can be a very intensive exercise due to Azure AD’s portal design. When customers only have a handful of CA policies it can be very easy and quick. However, when reviewing many policies it can quickly become impossible and overwhelming. When having to expand out every policy and sub config, it’s easy to forget all the options and what each policy did.

So to help with this, I wrote a Powershell script to help export these into an easier-to-audit and human-readable format. You might say, “But Doug, there are plenty of other options for exporting!” While this may be true, most of the options I found relied on GraphAPI calls that have proven difficult for clients to set up. Additionally, many of the outputs for these scripts did not help make my analysis easier. So the script below relies only on the Azure AD PowerShell module and hopefully makes it easier to read the policy configs.

Hope this helps you, and if it does send me a note and let me know. @Dougsbaker

CA-Export/Export-CaPolicy.v1.ps1 at main · dougsbaker/CA-Export (github.com)

Script Features

• Only Requires AzureAD PowerShell Module
• Exports to HTML Grid View
• Ability to highlight Control / Condition

Features I am considering adding

• Moveable Columns / Filters to hide
• Multiple output formats
• Export/Restore option
