1Security Microsoft Copilot Security vs Duality Platform: Side-by-Side Comparison (2026)

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.

Duality Platform

Mid-market and enterprise organizations that need to collaborate on sensitive data without exposing raw datasets will find Duality Platform's value in query-level encryption; you can run analysis across external data while both parties keep information private, which is genuinely rare. The platform covers PR.DS and ID.AM through its multi-layer privacy-enhancing tech stack (homomorphic encryption, secure multiparty computation, federated learning, trusted execution), and the federated analytics capability means data never leaves each participant's control. Skip this if your use case is internal data governance within a single organization; Duality is built for cross-party collaboration, not for locking down your own data lakes.
