What the comparison says

Microsoft Defender XDR is SaaS only and ESET Inspect is self-hosted. Where your obligations dictate residency, that difference tends to settle the choice before any score is read.

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

Microsoft Defender XDR leads on integrations. ESET Inspect leads on residency.

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.

ESET Inspect

  • +On-premises ESET PROTECT server available. That is a genuine self-hosted control plane.
  • +Very low endpoint performance impact compared with most agents here.
  • +Strong false-positive control, which reduces analyst load meaningfully.
  • −Managed detection service is less mature than managed-first competitors.
  • −Advanced threat intelligence features require additional tiers.

Best for SMB and mid-market wanting self-hosted EDR with a light agent footprint.

Watch out ESET is folding the cloud Inspect console into ESET PROTECT through 2027. On-premises Inspect is unaffected, so specify the on-prem build.
