Recommendations for utility to pull full site permissions audit of my SharePoint Online environment?

Question

Is there a recommendation for a tool that will allow me to export a report showing the various group permissions across the various sites, document libraries, etc. in my SharePoint Online environment?

Hi @OneTech IT ,

You could use PowerShell to export permissions report as a workaround.

PowerShell:

#sharepoint online powershell permissions report  
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"  
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"  
  
#To call a non-generic method Load  
Function Invoke-LoadMethod() {  
    param(  
            [Microsoft.SharePoint.Client.ClientObject]$Object = $(throw "Please provide a Client Object"),  
            [string]$PropertyName  
        )  
   $ctx = $Object.Context  
   $load = [Microsoft.SharePoint.Client.ClientContext].GetMethod("Load")  
   $type = $Object.GetType()  
   $clientLoad = $load.MakeGenericMethod($type)  
     
   $Parameter = [System.Linq.Expressions.Expression]::Parameter(($type), $type.Name)  
   $Expression = [System.Linq.Expressions.Expression]::Lambda([System.Linq.Expressions.Expression]::Convert([System.Linq.Expressions.Expression]::PropertyOrField($Parameter,$PropertyName),[System.Object] ), $($Parameter))  
   $ExpressionArray = [System.Array]::CreateInstance($Expression.GetType(), 1)  
   $ExpressionArray.SetValue($Expression, 0)  
   $clientLoad.Invoke($ctx,@($Object,$ExpressionArray))  
}
