What the comparison says

Bitdefender GravityZone XDR is hybrid and Microsoft Defender XDR is SaaS only. Where your obligations dictate residency, that difference tends to settle the choice before any score is read.

Bitdefender GravityZone XDR licenses on per endpoint, Microsoft Defender XDR on M365 E5 licence tier. Neither bills on data volume, so the comparison is about what each licence includes rather than how much you send it.

Bitdefender GravityZone XDR leads on residency. Microsoft Defender XDR leads on integrations.

Bitdefender GravityZone XDR

  • +Consistently top results in AV-TEST and AV-Comparatives independent testing.
  • +On-premises GravityZone deployment available, unlike most XDR vendors here.
  • +One platform covers endpoints, servers, virtual machines and cloud workloads.
  • −Console navigation flagged as complex by a meaningful share of reviewers.
  • −Deep scans can affect performance on older endpoint hardware.

Best for Organisations wanting proven detection with an on-premises management option.

Watch out Verify which XDR features are available in the on-premises build specifically.

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. There is 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.
