1Security Microsoft Copilot Security vs Cyberhaven Data Security Posture Management: 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.

Cyberhaven Data Security Posture Management

Mid-market and enterprise teams drowning in unclassified data across endpoints and cloud will find Cyberhaven Data Security Posture Management's AI-driven classification and data lineage tracking actually useful instead of another scanning tool that dumps alerts. It covers the full NIST Identify and Protect spectrum,asset discovery, risk assessment, and data-at-rest controls,without forcing you to bolt on separate DLP systems. Skip this if your organization lacks basic data governance discipline or expects one tool to also handle identity access management; Cyberhaven assumes you know what data matters and why.
