1Security Microsoft Copilot Security vs PKWARE PK Protect: 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.

PKWARE PK Protect

Mid-market and enterprise security teams with sensitive data spread across mainframes, databases, and cloud will get the most from PKWARE PK Protect; mainframe data protection via copybooks is genuinely rare in this category and solves a real problem legacy tools ignore. The platform covers ID.AM and ID.RA well through discovery and classification across hybrid environments, though its data masking and redaction lean toward output protection rather than preventing exfiltration at rest. Skip this if your primary concern is endpoint DLP in motion or if you need a single pane of glass for network and data security; PK Protect is deliberately focused on data itself, not the channels it travels through.
