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
Elastic Security
- +Fully self-hostable with no vendor lock-in on your own data
- +Unified SIEM, endpoint and threat hunting on one searchable platform
- +Very large integration library and an active open community
- −Requires genuine Elasticsearch operational expertise to run well at scale
- −Machine learning and several security features sit behind paid tiers
Best for Engineering-capable teams wanting an open platform they fully control
Watch out The licence may be free but the operational cost is not — staff for it honestly
