1Security Microsoft Copilot Security vs archTIS Spirion: 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.

archTIS Spirion

Mid-market and enterprise security teams drowning in unstructured data across hybrid environments need archTIS Spirion for its 98.5% discovery accuracy and ability to scan both cloud and on-premises systems simultaneously, where most competitors force you to choose. The persistent data labeling and real-time policy enforcement across Microsoft 365 and SharePoint mean you're not just finding sensitive data, you're actually remediating it before exposure happens. Skip this if your organization has minimal cloud footprint or runs primarily on non-Microsoft platforms; the integration depth here is built for enterprises already committed to M365.
