1Security Microsoft Copilot Security vs Obsidian Security - App-to-App Gov.: 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.

Obsidian Security - App-to-App Gov.

Mid-market and enterprise security teams drowning in SaaS integration sprawl need Obsidian Security - App-to-App Gov. because it's the only tool that actually maps where your data flows between apps instead of just counting how many integrations exist. The normalized view of active and inactive integrations, paired with dataflow visualization tied to data sensitivity levels, directly addresses NIST ID.AM and PR.DS controls that most SaaS security programs bungle. Skip this if your organization has fewer than 50 SaaS applications or treats integration governance as a one-time audit task; the operational overhead only pays off when you're managing hundreds of live connections across teams.
