First edition · Reviewed · Rubric 1.1
Six dimensions, each scored 0.0–5.0 in tenths. Gaps stay visible.
Commercial Microsoft 365 inbound email protection configured for reviewable verdicts and mailbox response. Compare the stated native, integrated or API configurations as alternative operating workflows. This is not a latency or detection-efficacy ranking; inline and post-delivery paths remain explicit. Collaboration, archiving, managed response and unrelated identity products are excluded.
Each row is one 0.0–5.0 dimension. Every assessed offering has a consistent color, shape, and number. Numbers identify offerings, not rank. Unknown scores are omitted.
Separated marks connect to their exact positions. Separation does not change scores.
Momentum: building history. Numbers identify offerings, not rank; lines between dimensions are profiles, not time.

Review history & what changed
The 2026-09-21 baseline incorporates the six-dimension review. Decimal calibration and research corrections are not product momentum. Unknowns stay unknown.

Operational maturity
Can an operator inspect a verdict, apply policy-driven response and recover from a false positive?
Documented progression from message inspection to controlled response. Native and API paths can satisfy the same operational stage; delivery timing remains a constraint.
Native Plan 2 investigation and permissioned response are documented. The assessment does not treat every AIR action as unattended or infer superior detection.
Score3.6 / 5.0medium confidence
Comparison:
Rationale and sources
Explorer and AIR establish review and policy-driven response. Release permissions add 0.4 and documented AIR trigger/approval limits add 0.2; scoped rollout was not independently established in this pass.
How this score is built
3.0 anchor + 0.6 credited progress = 3.6
Next anchor: 4 — Stage 3 plus an eligible-message restore path, explicit operating limits and policy scope restricted to users, groups or domains.
+0.4 · Documented return of an eligible remediated message to its mailbox or approved release
Quarantine guidance defines administrator release and user release requests.
Not credited: 0.4 · Documented restriction of enforcement policy to named users, groups or domains
Not established by this assessment; no credit. This does not establish absence.
Weights are shared editorial rules for this dimension and anchor interval. They are not measured performance differences.
Constraints
Plan 2 is required for the assessed investigation workflow. Some AIR actions require approval; documented cluster auto-remediation has narrower behavior.
Public documentation review only; no tenant deployment, detection benchmark, performance measurement or procurement quote was performed.
A score describes documented workflow in this selected scope. Unknown cells do not mean the capability is absent.
Baseline established 2026-09-21 from current public primary sources; no historical momentum is inferred.
A common Microsoft 365 outcome makes these workflows comparable, but their mail paths differ. Do not interpret proximity on the chart as equal protection latency or efficacy.
Integer ties are preserved. The shared maturity refinement awards only documented parts of the next anchor; weights total ten tenths. Documentation alone earns at most medium confidence.
Public documentation availability affects confidence and coverage. API functionality, licensing and tenant behavior require a controlled pilot; unsupported higher-anchor claims are not guessed.
How to read these scores
Scores use tenths from 0.0 to 5.0 against published anchors. Fractional scores credit documented requirements toward the next anchor; the inspector exposes the calculation. Equal evidence can still produce a tie. Null means unknown and is never treated as zero. Views never average or blend dimensions into an overall winner. Cohort membership is the only comparison boundary.
