Sanctioned external sharing is an attack surface. This report from Chief Strategy & Trust Officer Mike Towers shows how to govern data after it leaves your environment—where DLP, CASB, DSPM, and SSPM visibility typically ends.

What you'll learn:

• Why outbound, authorized collaboration across email, Teams, SharePoint, OneDrive, and shadow IT quietly creates continuous exposure.
  
• Why “now” is different; multi‑channel sprawl, AI‑agent velocity, and regulators demanding continuous control.
  
• The Path Forward: a practical blueprint for post‑share governance. Persistent download restrictions, unified visibility, recipient activity monitoring, classification‑based policies, and complete audit trails.

Can your team answer these five burning questions?

• How many external shares happened last month across all channels?
  
• Which shares include confidential or regulated data?
  
• Can we restrict downloads for external recipients?
• Do we have audit trails of what external recipients did?
• If a partner uploads our data to ChatGPT tomorrow, will we know?
