How to exclude large groups from Maester scanning?

[dattebayo-ua]

Hi everyone!

I'm running into a performance issue with Maester in Azure DevOps Pipelines and hoping the community can help.

The Problem

My Maester security assessments are timing out after 3 hours when scanning large groups (3,000+ identities). The pipeline gets stuck during group member enumeration and eventually gets cancelled automatically.

Environment:

• Azure DevOps Pipelines
• Maester 1.3.0
• Groups with 3,000+ identities

My Questions

1. Is there a supported way to exclude specific groups from Maester scanning?

   • Maybe a parameter I'm missing?
   • Configuration file option?

2. How do others handle large "All Company" type groups?

   • Do you typically need to scan these for security policies?
   • Any performance optimization tips?

What I'm Looking For

Ideally, it'd be great to have something like:

Invoke-Maester -ExcludeGroups @("All Company Users", "Large Distribution List")

Impact

This is blocking our CI/CD security automation since pipelines can't complete successfully. Large groups often don't need the same policy enforcement as administrative groups anyway.

Reproduction

1. Run Maester against tenant with 3,000+ member groups
2. Watch it hang during group enumeration
3. Pipeline times out after 3 hours
   I've used a code from a Setup guide

$accessToken = (Get-AzAccessToken -ResourceTypeName MSGraph).Token
Connect-MgGraph $accessToken -NoWelcome
          
Install-Module Maester -Force
Update-Module Maester -Force

# Configure test results
$PesterConfiguration = New-PesterConfiguration
$PesterConfiguration.TestResult.Enabled = $true
$PesterConfiguration.TestResult.OutputPath = '$(System.DefaultWorkingDirectory)/test-results/test-results.xml'

# Run Maester tests
Invoke-Maester -Path $(System.DefaultWorkingDirectory)/tests/Maester/ -PesterConfiguration $PesterConfiguration -OutputFolder '$(System.DefaultWorkingDirectory)/test-results'

Has anyone solved this or found a workaround? Any guidance from the maintainers would be greatly appreciated!

Thanks in advance!
