CIAOPS Security and Microsoft 365 Advisory

Exchange Online + Defender for Office 365 Policy Flow Simulator

Simulate how one message moves through Exchange Online Protection (EOP) and Defender for Office 365 policy layers. This flow is grouped to match Microsoft's public protection phases rather than imply a private exact internal execution order. Toggle posture to see how layered controls reduce phishing success, malware execution, and business email compromise impact.

Learning Coach Waiting

Run the simulation in Learning mode to step through each policy stage.

Why this matters: each control adds a layer that can reduce business risk.

Pass / Allow with controls Quarantine / Warning / Rewrite Blocked / Dropped

Representative grouped model: phases below reflect how Microsoft describes protection layers publicly. Some controls overlap, run conditionally, or act after delivery rather than as one strict serial pipeline.
