Microsoft Defender XDR
- +Effectively free at the margin for organisations already licensed for M365 E5
- +Deepest possible integration with Entra ID, Exchange and the Microsoft estate
- +Security Copilot adds AI-assisted investigation without a separate purchase
- −Runs in Azure only — no on-premises deployment at any tier
- −Coverage is materially weaker across non-Windows endpoints and Linux servers
Best for Microsoft-centric enterprises already paying for E5 Security
Watch out Value collapses outside the Microsoft stack, and residency is fixed to Azure regions
Sophos Intercept X / XDR
- +Deep learning detection stops ransomware without relying on signatures
- +Security Heartbeat auto-isolates a compromised endpoint at the firewall
- +Among the easiest platforms in this table to operate with a small team
- −Managed through Sophos Central — no self-hosted management plane
- −Full detection and response capability requires the Sophos MDR add-on
Best for SMB and mid-market teams wanting strong protection with minimal operational load
Watch out May reach practical limits above roughly ten thousand endpoints
