About this tool

The Oversharing Detection tool identifies six types of sharing risks across your SharePoint environment. Find anonymous links that allow anyone on the internet to access your content, "Everyone" permissions that open files to all organization members, and excessive external sharing. Prioritize findings by risk level to focus remediation on the most critical exposures. Export results with direct links to the shared content for quick remediation. Essential before deploying Microsoft Copilot or other AI tools that could surface improperly shared content.

Limitations & out-of-scope

Limited to the six risk types it's built to detect — anonymous links, Everyone permissions, and excessive external sharing across SharePoint — using Sites.Read.All and Group.Read.All, both read-only. It flags exposure; closing an anonymous link or tightening a permission is a manual step the administrator takes afterward. Teams-native chat sharing and Exchange mail-forwarding rules are separate exposure vectors this SharePoint-scoped tool does not examine.

Inside the tools catalog

The catalog spans 49 admin capabilities across backup, audit, export, security, migration. Every tool runs under client-side encryption. Tools share a vault, schedule engine, plus reporting layer.

About the platform

This is a zero-knowledge toolkit. It helps IT admins, MSPs, security teams run their cloud safer. Use it inside a browser. Or install our Mac or Windows app.

Tenant credentials and vault contents are encrypted in your browser; the server holds ciphertext it cannot open. What the server can read is listed at /trust: account and billing metadata, OAuth tokens during the sign-in handshake, license tokens, migration job metadata, opt-in crash reports, redacted operational logs, and cloud export output for your plan's retention window.

How it works

  1. You unlock a local vault with a passphrase. Argon2id stretches it.
  2. Credentials get sealed with XSalsa20-Poly1305 before any sync.
  3. X25519 protects shared keys. Ed25519 signs every action.
  4. Each operation runs against Graph from your device, not ours.
