1Security Microsoft Copilot Security vs Fr0ntierX: 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.

Fr0ntierX

Enterprise and mid-market security teams handling sensitive AI workloads or regulated data should pick Fr0ntierX for encryption that persists through computation, not just at rest. The platform encrypts data in use via Trusted Execution Environments and multi-party computation, which directly strengthens PR.DS and PR.PS coverage where most DSPM tools stop at transit and rest encryption. Skip this if your workloads are stateless or cloud-native without compliance requirements around data processing itself; Fr0ntierX's value concentrates in organizations processing confidential information that can't afford decryption windows.
