The Copilot Blast Radius

A New Governance Lens for SharePoint in the AI Era

We used to think of SharePoint as storage.

Then Copilot came.

Microsoft built a world-class foundation.

🔹 DLP protects classified content.

🔹 Purview defines what’s sensitive.

🔹 Sentinel detects deviations and threats.

But in the Copilot era, the question shifts:

How far can one SharePoint permission mistake travel through Teams, search, OneDrive, and AI-generated content?

That’s where Rahsi architecture begins.

We don’t replace Microsoft.

We extend it.

Rahsi Blast Radius Lens™ maps propagation across:

Inheritance loops
Link-state exposure
Guest residue
Device posture gaps
Inference trails Copilot can silently follow

It turns Microsoft’s detection + classification into containment + closure proof.

So I built this lens:

“The Copilot Blast Radius” — a tenant-scale diagnostic that exposes:

🔹 Permission Drift → AI Inference Paths

🔹 SharePoint → Teams → Loop Leak Vectors

🔹 Context Merge Zones in M365

🔹 Telemetry-Governance Gaps Copilot Amplifies

🔹 Evidence Loss across CVE-triggered change events

🔹 Why zero trust isn’t enough for Copilot

This is not a post.

This is a governance weapon.

Quiet.

Humble.

Surgical.
