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.
Mid-market and enterprise teams drowning in shadow data across hybrid infrastructure need DataGuard specifically for its AI-powered discovery that actually finds what you've missed, not just what you already know about. The platform maps data flows into AI training pipelines and RAG systems, then enforces controls through automated remediation, which means you're covering the ID.AM and PR.DS gaps that most DSPM tools skip. Fair warning: this is an on-premises deployment that requires container orchestration overhead, and it leans hard into detection and response while leaving incident recovery largely to you and your SOAR integrations.
