1Security Microsoft Copilot Security vs Metomic: 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.

Metomic

Mid-market and enterprise teams drowning in SaaS sprawl will get the most from Metomic because it actually finds sensitive data where it lives,Slack, Drive, SharePoint,rather than assuming it stays in your database. The platform covers ID.AM and PR.DS strongly with automated discovery and policy enforcement across ten-plus integrations, so you're not manually hunting PII across disconnected tools. Skip this if you need deep network monitoring or endpoint controls; Metomic's strength is data classification and remediation in cloud apps, not lateral movement detection.
