1Security Microsoft Copilot Security is a commercial data security posture management tool by 1Security. DataStealth Data Discovery is a commercial data security posture management tool by DataStealth. Compare features, ratings, integrations, and community reviews side by side to find the best data security posture management fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise security teams drowning in data sprawl across cloud and on-prem will get immediate value from DataStealth Data Discovery because it actually finds what you've lost track of, not just what's in your inventory. Agentless deployment via DNS means you're scanning in days, not weeks, and the contextual metadata tie-in to system owners and data residency covers the ID.AM and ID.RA gaps most organizations live with. Skip this if you need post-discovery enforcement built in; DataStealth handles finding and classifying sensitive data cleanly, but remediation requires stepping into their tokenization platform.
