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 — 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
