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
Trellix XDR
- +Hybrid deployment options including on-premises management
- +Broad existing install base in government and large enterprise
- +Strong network detection heritage from the FireEye side of the business
- −Post-merger product consolidation has made the portfolio harder to navigate
- −Management experience rated below newer platforms by most reviewers
Best for Existing McAfee or FireEye estates consolidating onto one platform
