Security Fit Map / EDR / Protocol v1.0

Response on managed endpoints

A small team supporting a mixed Windows, macOS, and Linux fleet, with staged rollout and reversible containment.

UNASSESSED · RESEARCH PROTOCOL · 2026-09-19

This edition publishes the evaluation question and work still required. It contains no scored vendor points.

What must be true

  • Required operating systems and response actions are supported.
  • A contained device can be safely restored.
  • An action is attributable to an authorized responder.

Candidate scope

Two publicly documented offerings form a small pilot. Inclusion is for methodology development, not a claim that these are the only or best choices. Exact tiers and test configurations must be frozen before scoring.

OfferingScopeStatus
Microsoft Defender for EndpointPlan 2 candidate; device/server entitlements and platform feature differences require confirmation.Unassessed
Capability: null
Operating: null
Elastic DefendEndpoint protection integration; exact platform and subscription requirements remain unselected.Unassessed
Capability: null
Operating: null

Evidence still needed

  • An agreed device and OS version matrix
  • Repeatable endpoint behavior and recovery tests
  • Sensor overhead, administration, and licensing evidence

How the evaluation will work

  1. Fix the workload, organizational assumptions, product editions, and mandatory requirements.
  2. Publish criterion-specific 0–5 anchors before collecting results.
  3. Collect reproducible observations, source dates, and operating measurements. Preserve contradictory evidence.
  4. Use the rubric below without filling unknowns with estimates.
  5. Have a second reviewer reproduce results. Publish only after both axes reach 80% coverage and critical requirements have explicit results.

Threshold: 70/100 on each axis. A missing-evidence interval that spans 70 prevents a definitive quadrant label. A critical failure blocks a shortlist recommendation.
