Who this is for

Security leaders building or refreshing an EDR program: a mid-market SOC with 1–3 analysts, an enterprise SOC swapping out a legacy AV, or a managed-service buyer evaluating MSSP-bundled stacks. If you are still deciding between EDR, XDR or MDR, start there first — this article assumes you have settled on EDR as the layer to procure.

The 2026 EDR shortlist

These are the products that show up in the final round of real procurements across mid-market and enterprise buyers. Order does not imply ranking.

  • CrowdStrike Falcon — the market-default. Strong telemetry depth, great Overwatch managed-hunt option, premium pricing.
  • Microsoft Defender for Endpoint (P2) — included in many E5 SKUs; the buy is mostly free if you already have E5 and good on Windows, weaker on Mac/Linux.
  • SentinelOne Singularity — the strongest single-agent / autonomous-response story; aggressive on price for displacement deals.
  • Palo Alto Cortex XDR / XSIAM — best if Palo Alto already owns your network; strong correlation, heavy platform spend.
  • Sophos Intercept X — mid-market favourite; strong MDR add-on; under-rated on detection quality.
  • Bitdefender GravityZone — strong technical detection at price points that mid-market actually pays.
  • Trend Vision One — hybrid + Asia-Pacific strength; XDR ambitions; broad fleet support.
  • Cybereason — attack-story-led UX, popular with smaller in-house SOCs.
  • Elastic Defend — if the data layer already lives in Elastic and the team has engineering bandwidth.
  • VMware Carbon Black — still present in enterprise refreshes; check Broadcom roadmap before committing.

A 9-point rubric to score them

  1. Telemetry depth. What process / file / network / registry events does the sensor capture at default and at maximum verbosity? Capture sample EVTX-equivalent logs in your POC.
  2. Detection content quality. Out-of-the-box MITRE ATT&CK coverage by tactic, plus false-positive rate measured on your real traffic.
  3. Response actions. Network isolation, process termination, file quarantine, registry rollback, live response shell — latency and reliability on each.
  4. Platform coverage. Windows is solved; demand parity on macOS and Linux (especially server distros) before signing.
  5. OS / kernel survivability. Does the agent break on Windows feature updates? Audit the vendor’s OS-update incident history.
  6. Performance overhead. Run a 14-day soak on a representative workstation pool and capture CPU / disk / network deltas.
  7. Console + analyst UX. Median time-to-pivot from alert to root host, measured by a non-vendor analyst.
  8. Integration breadth. SIEM, SOAR, IdP, ticketing, ITDR. Beware "supported" that means "via REST polling".
  9. Cost model. Per-endpoint per-year, retention tier, what triggers an upcharge (e.g. cloud workload license).

Mistakes to avoid

  • Buying tier-1 EDR with no analyst plan. A great agent without 24/7 triage is wasted spend. Pair with an MDR if the in-house SOC has gaps.
  • Treating "AI-driven" as a differentiator. Every vendor will say it; demand a measured signal-to-noise improvement on real data.
  • Ignoring the EDR → XDR pull. If the vendor's XDR story relies on you also buying their email / network / cloud, model that future cost up front.
  • Skipping the security of the agent itself. EDR agents are themselves a privileged blast radius — review the vendor's recent CVEs and signing posture.

When to skip standalone EDR and buy MDR

If you do not have a named owner for "alerts after 6pm", you do not have a SOC — you have an EDR tab no one looks at. Buy MDR or buy MDR-bundled EDR (Arctic Wolf, Huntress, Red Canary, Expel). The premium is real but the marginal value of a $200K EDR with no analyst on it is close to zero.
