1Security Microsoft Copilot Security vs Thales CipherTrust 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.

Thales CipherTrust Data Security Platform

Mid-market and enterprise teams managing sensitive data across hybrid infrastructure should choose Thales CipherTrust Data Security Platform for its transparent encryption that works at the database and file layer without forcing application rewrites. The platform covers PR.DS (Data Security) and PR.PS (Platform Security) across on-premises, cloud, and Kubernetes environments simultaneously, which most competitors handle poorly. Skip this if your priority is detection and response; CipherTrust is encryption-first and assumes your data is already classified.
