1Security Microsoft Copilot Security vs Virtru Data Security Platform: 2026 Comparison

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.

Virtru Data Security Platform

Mid-market and enterprise teams that need to keep encrypted data usable after it leaves your perimeter should build around Virtru Data Security Platform. Its persistent encryption with attribute-based access control means you can revoke or expire access to shared files months after they've left your environment, addressing the PR.DS and GV.PO gaps most data security tools ignore. Skip this if your priority is detecting data exfiltration in real-time; Virtru assumes data will move and focuses on controlling it after the fact, not stopping it before.
