1Security Microsoft Copilot Security vs Glasswall ICAP: 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.

Glasswall ICAP

Mid-market and enterprise security teams handling high-volume file traffic across email and web gateways should prioritize Glasswall ICAP for its content disarm and reconstruction engine, which removes threats without blocking legitimate files. The tool's ICAP server architecture integrates directly into existing proxy and gateway infrastructure, meaning you get real-time threat removal without ripping out your perimeter stack. Skip this if your organization relies heavily on allow-listing or has minimal file exchange friction; ICAP overhead becomes unjustifiable when your threat model doesn't center on malicious document payloads.
