Please read this security guide. Identify any risks or conflicts 
with our current setup before deploying.

Follow the Agent-Assisted Deployment Workflow in this guide.

Please deploy this defense matrix exactly as described in the guide. 
Include the red/yellow line rules, tighten permissions, and deploy 
the nightly audit Cron Job.

Run the validation tests from the Red Teaming Guide to ensure 
defenses are working correctly.
