1Security Microsoft Copilot Security vs Privacera Centralized Data Access Control: 2026 Comparison

1Security Microsoft Copilot Security

Security teams deploying Microsoft Copilot across M365 need visibility into what data the AI can actually access before oversharing becomes a compliance liability, and 1Security Microsoft Copilot Security is built explicitly for that pre- and post-deployment control. The tool maps Copilot's permissions through Microsoft Graph, flags excessive access across SharePoint and OneDrive, and automates remediation of misconfigurations, addressing the asset management and data security gaps that most M365 tenants haven't solved yet. Skip this if your organization hasn't standardized on Microsoft's ecosystem or if you're looking for a Copilot governance tool that also covers other generative AI platforms; 1Security is Microsoft-only.

Privacera Centralized Data Access Control

Mid-market and enterprise teams managing data across multiple clouds or hybrid environments should choose Privacera Centralized Data Access Control because it actually enforces access policy at the row and file level across 50+ data services, not just at the database layer. The federated data ownership model means business teams can own their own policies without waiting on centralized security, which cuts through the typical bottleneck where access requests pile up. Skip this if your data lives mostly in a single platform or your access patterns are simple enough that standard RBAC handles them; the complexity Privacera solves is real, but only if you have it.
