1Security Microsoft Copilot Security vs Mage Data DSPM: 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.

Mage Data DSPM

Mid-market and enterprise teams managing data across on-premises, cloud, and SaaS environments will see immediate value from Mage Data DSPM because it enforces consistent classification and protection policies without requiring separate tools per deployment type. The platform's asset-class-aware approach and end-to-end data lineage tracking directly addresses NIST ID.AM and PR.DS requirements, cutting through the fragmentation that typically forces security teams to stitch together point solutions. Skip this if your data footprint is purely cloud-native and you're already comfortable with native cloud DLP; Mage Data's hybrid strength becomes less critical in single-environment shops.
