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
Wazuh
- +Genuinely free and open source with no licence cost at any scale
- +Mature rule engine, file integrity monitoring and configuration assessment
- +Fully self-hosted and air-gap capable with a large community rule base
- −The surrounding stack — indexer, dashboards, storage — is where the real cost lands
- −Operational burden falls entirely on your team unless a support contract is bought
Best for Teams with platform engineering capacity and a strong preference for open source
Watch out Budget for the indexing layer and the engineer who maintains it
