1Security Microsoft Copilot Security vs Sentra 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.

Sentra DSPM

Mid-market and enterprise security teams drowning in SaaS and cloud storage sprawl need Sentra DSPM because it actually finds sensitive data across your entire stack without agents or painful API integrations. The 95%+ accuracy on AI-based classification means you're not chasing false positives, and agentless discovery across IaaS, PaaS, SaaS, and on-premises eliminates the typical deployment friction. Skip this if you're looking for a tool that also does identity governance or CSPM; Sentra is deliberately narrow and data-focused.
