How Calibrant compares to
CIS-CAT Pro, CoreView & Microsoft’s built-in tools
Four different approaches to M365 security and compliance — including the Secure Score and Compliance Manager tools already in your tenant. This page gives clear verdicts where the published products genuinely differ, shows the rows Calibrant loses, and says when each tool is the right choice.
Where each tool leads
Clear verdicts where the published products genuinely differ — including the rows Calibrant loses. Reviewed August 14, 2026; competitor products and licensing can change.
published core strength partial / license-dependent not in the published product
| Capability | Calibrant | CIS-CAT Pro | CoreView | Secure Score & Compliance Manager |
|---|---|---|---|---|
| Published flat pricing | $8–$20/mo flat, unlimited users | SecureSuite membership from $2,400/yr | Request pricing | Secure Score included; premium Compliance Manager templates licensed |
| Multi-framework M365 assessment in one console | 140-control baseline + SCuBA + Essential Eight ML1–ML3 | CIS Benchmarks | CIS-aligned configuration baseline | Compliance Manager templates vary by licensing; Secure Score maps no external framework |
| Official CIS assessment output | Informational CIS v6 cross-references only | The official CIS tool | Alignment stated; not official output | Premium Compliance Manager template where licensed |
| Attestation and evidence trail | Append-only history: who attested what, on what basis, with expiring compensating safeguards | Configuration scan output | Not its published focus | Compliance Manager owners, notes, and document evidence |
| Audit-ready PDF report | Every plan — per-control evidence, provenance, and decisions in one document | Conformance report formats | Operational reporting and dashboards | Compliance Manager assessment reports; Secure Score dashboard and API |
| Tenant remediation and rollback | Guidance only — reads, never writes, by design | Remediation content with SecureSuite | Remediation and configuration restore are the headline | Recommended actions link to fixes you apply |
| Available in your tenant today, nothing to deploy | One relay VM in your own Azure subscription | Assessor installation through SecureSuite | SaaS onboarding of your tenant | Built into the Defender and Purview portals |
Official sources: CIS Microsoft 365 Benchmark, CIS-CAT Pro, CoreView baselines, CoreView pricing, Microsoft Secure Score, and Microsoft Purview Compliance Manager.

The bottom line
Each of these tools genuinely wins somewhere. Pick by the job in front of you — and note that Microsoft's built-in tools are complements, not substitutes, for an evidence-grade assessment.
Choose Calibrant
When you need an auditor-ready, multi-framework M365 assessment — evidence trail, attestations, and PDF reports — at a flat $8–$20/mo without E5 licensing or GRC platform overhead. Not the pick when you need official CIS output or a tool that remediates the tenant for you.
Choose CIS-CAT Pro
When a contract, insurer, or certification path requires the official CIS assessment tool and SecureSuite membership fits the budget (from $2,400/yr; some public-sector and academic memberships are no-cost). Not the pick for a continuously maintained M365 posture console.
Choose CoreView
When the job is operating M365 at scale — delegated administration, configuration remediation, drift recovery — and you have budget for request-priced enterprise tooling. Not the pick when the goal is an independent assessment with an attestation trail.
Use Secure Score & Compliance Manager either way
They are already in your tenant: Secure Score is a free, continuously updated posture signal, and Compliance Manager adds regulatory templates under eligible licensing. What they do not provide is an independent, framework-mapped assessment with attestation provenance and an audit-ready export — which is the gap Calibrant fills alongside them.
Why teams choose Calibrant
Context-Aware Scoring
Calibrant reads Microsoft first, then asks a scan-specific follow-up only when configuration cannot prove intent, complete scope, justified exclusions, policy quality, or an allowed outside safeguard. Saved answers are reused while the relevant Microsoft evidence and Calibrant evaluation rules remain unchanged, so only affected items are asked again. One control receives one verdict, and required context is completed before a score is published.
Living Assessments
Saved answers remain available for safe reuse within their review window, while each completed scan keeps its own evidence, scope, scoring identity, and exception history.
Hybrid Attestation
When an exact control explicitly permits it, document an equivalent third-party safeguard with evidence and an expiry. The failed native Microsoft result remains visible.
Multi-Framework
Calibrant's independently authored 140-control M365 baseline, 134-control SCuBA snapshot, and the 150-requirement ACSC Essential Eight with ML1–ML3 maturity tracking in one console, with informational CIS v6 references where Calibrant has mapped an alignment.
Audit-Ready PDF Reports
Every assessment and Healthcheck scan exports a professionally composed PDF carrying what an auditor needs: per-control scan evidence with timestamps, who attested what and on what basis, licensing decisions, and the frozen policy snapshots behind the score. Included on every plan.
AI Insights
Framework-aware AI analysis for eligible final assessment data, with prioritized remediation recommendations, executive summaries, and weekly trend analysis.
SMB-Friendly Pricing
Calibrant publishes flat $8 and $20 monthly prices per tenant with no per-user fee. Competitor licensing models differ, so compare the current linked vendor terms for your organization.
Capability-Based Licensing
Checks use underlying Microsoft service capabilities rather than bundle names. Missing required capabilities remain visible gaps; only an explicit per-control policy can accept a documented, time-limited compensating safeguard.
