Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
SMB and mid-market teams with on-premises storage infrastructure need ProLion Storage Security for its automated response to ransomware; the moment it detects suspicious file access patterns, it blocks the offending user without waiting for human intervention, which cuts recovery time from hours to minutes. The platform covers the full incident lifecycle from continuous monitoring through granular file restoration, with 24/7 vendor support included as standard. Skip this if your storage lives entirely in cloud object services or if you need deep SIEM integration beyond basic log forwarding; ProLion's strength is protecting NAS and SAN environments where traditional access controls have already failed.
