What this covers

The exposure most organisations cannot see, until AI surfaces it.

Forty-five practical minutes on why sensitive data quietly accumulates in the wrong places, and what an AI assistant like Copilot will surface the moment you switch it on.

The root cause

Why joiner-mover-leaver processes without risk analysis quietly hand the wrong people access, and how it compounds over years.

OneDrive to public SharePoint

How sensitive files get copied into sites shared with "everyone", and become instantly searchable the day Copilot arrives.

Access that never gets cleaned up

Teams get renamed, libraries are forgotten, internal and external members pile up, and nobody owns the permissions.

Backups and migrated data

Old migrations and backups left in insecure locations, and post-incident data still sitting exposed long after.

What Copilot actually surfaces

Real Microsoft 365 examples of an AI assistant returning data its user should never have been able to reach.

How to get ahead of it

The practical order of work, discover, classify, tighten access, add guardrails, so you adopt AI with confidence.
