Prevent M365 Oversharing & Client-Side PII Leakage
Deploying Microsoft Copilot in Excel, Word, or browser chats? Enforce client-side data minimization to prevent internal oversharing, payroll leaks, and cloud logging.
Use PrivacyScrubber to tokenize sensitive data in your browser before it ever reaches Microsoft Copilot. Zero installation required.
| Risk Factor | Microsoft Default | With PrivacyScrubber |
|---|---|---|
| Internal Permission Oversharing | Subject to tenant ACL permissions | Blocked at source (RAM) |
| Cloud Diagnostic Logging | Diagnostic & audit logging enabled | Zero logs (local tokenization) |
| Spreadsheet & Financial Masking | Full cloud upload required | Wasm local batch redaction |
| Reversible Data Masking | No | Yes — instant local restore |
Sanitize large CSVs, employee compensation rosters, and customer CRM exports locally before feeding them to Microsoft Copilot for formula generation or financial summaries.
Microsoft 365 Copilot accesses tenant data based on broad SharePoint permissions. Sanitizing sensitive inputs at the endpoint level ensures un-redacted PII is never indexed into corporate Copilot graphs.
Seamlessly protects Copilot Web (copilot.microsoft.com), Bing Chat Enterprise, and Office Online web apps without requiring complex enterprise Microsoft Purview DLP agents.
