What a Microsoft 365 audit tool needs to do in 2026
An audit tool earns its place by doing four things well, across the whole stack.
Find misconfigurations and map them to compliance
Surface risky settings across Microsoft 365, Intune, Defender, Entra ID, and Purview, not a narrow slice of identity. Then tie each finding to recognized frameworks so an audit becomes evidence, not guesswork.
Report clearly and help you remediate
Clear output that an executive, a client, or an auditor can read without translation. And because a finding is half the job, the fix, ranked and validated, is what closes the gap.
How we chose these tools
This is a curated shortlist, not a scrape of every script on GitHub. The Senserva security team uses these tools in real Microsoft 365 audit work, and each one earns its place only by meeting all six criteria below. Where a tool is strong but narrow, we say so and point to what pairs with it. We do not rank the tools against each other, because they solve different problems: the comparison that matters is by category, which the table further down lays out.
Each tool solves a concrete part of a Microsoft 365 audit, a secure-configuration baseline, Conditional Access, email protection, forensics, configuration-as-code, or identity internals, and does that one job better than a general-purpose utility.
Built by Microsoft, by CISA, or by recognized Microsoft MVPs and security researchers, the people whose work the community already trusts and cites. We link every project to its official home so you can verify the source.
A living project with ongoing updates and real-world use across the Microsoft security community, not an abandoned script that assumes a portal or API that has since changed.
Open source you can read, or a free tool from an authoritative source. On a page about auditing, a black box does not belong. Free means free to use; check each project for its exact license.
We include a tool only when we can state plainly where it stops, so you know what to pair it with. Every card below names that limit, because a shortlist that pretends nothing has trade-offs is not a reference.
These are the tools Senserva actually uses, and each maps to part of our own 650+ check catalog, so the pairing we describe is real, not theoretical.
The free and community tools, all in one place
The Microsoft MVP and open-source community has built a remarkable set of free Microsoft 365 audit tools. We use several of them, we link every one to its official project, and we recommend them honestly: each does one thing well, and each stops short of a full posture program. That last part is where Senserva picks up.
14 tools, alphabetical within each group. Free means free to use; check each project for its license.
Baseline and posture assessment
The official SCuBA baseline assessment: PowerShell that checks a tenant against CISA's published Microsoft 365 secure configuration baselines and produces an HTML report.
Limit: Pass/fail against one baseline; no Severity ranking across findings and no remediation execution.
A Pester-based test framework for Microsoft 365 and Entra ID with hundreds of community-maintained tests; great in CI pipelines for repeatable verification.
Limit: Test results, not a posture program: prioritization, trending, and reporting are on you.
Open-source security review of Microsoft 365 and Azure subscriptions with benchmark-mapped findings and an HTML report.
Limit: A point-in-time review; scheduling, multi-tenant fleets, and fixes are out of scope.
Microsoft's free Zero Trust assessment workbook for Entra ID and devices, with a roadmap-style report.
Limit: A guided assessment, run occasionally; not continuous monitoring.
Microsoft's Entra ID configuration assessment module, the same data an identity architect would pull in a health engagement.
Limit: Identity only, and the output expects an expert reader.
Where Senserva picks up: these tell you pass or fail against a baseline on the day you run them. Senserva runs 650+ checks continuously (each with its own reference page), ranks every finding by Severity, maps it to SCuBA, CIS, NIST, HIPAA, and SOC 2 as audit evidence, and proposes validated, approve-before-apply fixes.
Conditional Access and identity deep dives
A PowerShell toolbox for Conditional Access and Zero Trust work: export, document, and analyze CA policies, simulate changes, find gaps.
Limit: Conditional Access focused; the rest of the tenant needs other tools.
Turns your Conditional Access policies into readable documentation and diagrams in one click; auditors love the output.
Limit: Documentation, not assessment: it shows what policies say, not whether they are enough.
Conditional Access gap analysis: enumerates every permutation your CA policies cover and, more importantly, the ones they do not.
Limit: One job, done well; pair it with broader tenant coverage.
An Entra ID exploration framework that dumps and lets you query the directory the way an attacker would enumerate it.
Limit: A researcher's lens: fantastic visibility, no compliance mapping or guardrails.
Checks which Microsoft services actually enforce MFA for an account by attempting sign-ins across protocols; a fast way to find MFA coverage holes.
Limit: Single-account spot checks from the attacker's side; use with authorization.
The deepest community toolkit for Entra ID internals: auditing, forensics, and research capabilities the portal will never show you.
Limit: Expert dual-use tooling; powerful in skilled hands, easy to misread without them.
Where Senserva picks up: identity is Senserva's largest check domain, 200+ checks across Conditional Access, PIM, authentication methods, and risky sign-ins, connected to the device and workload picture these single-focus tools cannot see, and open to your own AI through the Claude MCP integration.
Email security, forensics, and configuration-as-code
The Office 365 Recommended Configuration Analyzer: deep, focused checks of Defender for Office 365, anti-spam, anti-phish, and mail flow protections.
Limit: Email protection only; identity, devices, and the rest of the tenant are out of scope.
PowerShell incident-response and forensics collection for Microsoft 365: sign-in histories, mailbox rules, audit log pulls when you suspect compromise.
Limit: Built for after the incident, not for preventing it.
Configuration-as-code for Microsoft 365: export a tenant's full configuration, compare tenants, detect drift, and re-apply a known-good state.
Limit: An engineering tool with a real learning curve; it manages configuration rather than judging its security.
Where Senserva picks up: Senserva covers anti-phishing, anti-malware, and Safe Links posture as part of the same scan, keeps the audit-log health that forensics depends on under continuous watch, and turns drift into a ranked finding with AI Enhanced Reporting instead of a surprise.
The categories of Microsoft 365 audit tools
Each category has real strengths and honest limits. Most mature teams end up using more than one.
Native Microsoft tooling
Microsoft Secure Score, Microsoft Defender, and the Entra admin center are the baseline. They are built in, free with most licensing, and authoritative on Microsoft's own recommendations.
Pro: First-party, no extra cost, always current with Microsoft's guidance.
Con: A score is not a ranked action list, cross-tenant reporting is limited, and remediation is left to you.
Compare in depth: Microsoft Secure Score · Microsoft Defender
Open-source and security-as-code
CISA ScubaGear and Maester check your tenant against published baselines from a script you can read. They are transparent, free, and great for repeatable verification in a pipeline.
Pro: Transparent, free, version-controlled, and easy to automate.
Con: Raw pass/fail output, no ranked prioritization, and no validated remediation guidance.
Microsoft 365 management and governance platforms
Platforms such as CoreView and Quest handle broad Microsoft 365 administration, delegation, license management, and governance at scale. Security is one part of a wider management story.
Pro: Broad operational management, delegation, and governance across large estates.
Con: Security posture depth is lighter than a dedicated posture tool, and the focus is management first.
RMM and patch tools
Remote monitoring and management and patch tools keep endpoints running and up to date. They are operational by design and essential for IT delivery.
Pro: Strong on endpoint operations, patching, and day-to-day device health.
Con: Not built for Microsoft 365 posture or compliance mapping, so they leave the configuration audit gap open.

Dedicated Microsoft 365 security posture and remediation
This is the category Senserva sits in. It runs 650+ checks across Microsoft 365, Intune, Defender, Entra ID, and Purview, ranks posture by Severity, maps every finding to compliance frameworks, and produces AI-generated, Senserva-validated remediation. It supports MSP multi-tenant work, and AI is optional and bring-your-own-model via MCP. Browse the full checks catalog.
Pro: Deep, ranked posture plus the fix, compliance mapping, multi-tenant, no agents, no cloud service.
Worth knowing: it complements native and open-source tools rather than replacing the value they already give you.
| Criterion | Native Microsoft | Open-source | Management platforms | RMM and patch | Senserva |
|---|---|---|---|---|---|
| Coverage breadth | Broad but score-centric; strongest on identity and Defender surfaces | Focused on the published baseline (SCuBA policies, Maester tests) | Broad management coverage; security posture is lighter | Endpoints and patching only | 650+ checks across Microsoft 365, Intune, Defender, Entra ID, and Purview |
| Compliance mapping | Partial (Compliance Manager, score improvement actions) | One baseline per tool; no cross-framework mapping | Varies by module | No | Every finding mapped to SCuBA, MCSB, bridged NIST 800-171, and more |
| Remediation, not just findings | Guidance text; you implement manually | Pass or fail output; fixes are up to you | Operational actions, not security fix validation | Deploys patches; no configuration fixes | AI-generated, Senserva-validated fixes, ranked by Severity |
| Multi-tenant and MSP support | Limited cross-tenant reporting | Scriptable per tenant; you build the aggregation | Strong, built for delegation at scale | Strong for endpoints | Multi-tenant and MSP fleets, standardized from one place |
| AI optionality | Copilot add-ons, separately licensed | None | Varies | Varies | Optional and bring-your-own-model via the Senserva MCP |
| Agents and footprint | Built into the cloud service | Scripts, no agents | Cloud service | Agent on every endpoint | One local binary, no agents, no cloud service |
The criteria above map straight onto the categories described earlier. No category wins every row: native tooling is authoritative and free, open-source is transparent and automatable, platforms manage at scale, and RMM keeps endpoints healthy. Senserva is built to win the posture rows: coverage, mapping, and the validated fix.
Watch: from scan findings to boardroom-ready reports
What the audit output actually looks like when it reaches the people who asked for it. Open the watch page, or see all Senserva videos.
What to look for when you choose
Use this checklist to cut through marketing and match a tool to how your team actually works.
- Coverage breadth. Does it span Microsoft 365, Intune, Defender, Entra ID, and Purview, or stop at a few identity settings?
- Compliance mapping. Are findings tied to recognized frameworks so the audit produces evidence?
- Remediation, not just findings. Does it tell you how to fix each issue, ranked by Severity, or just hand you a list?
- Multi-tenant and MSP support. Can you run it cleanly across many client tenants if that is your model?
- AI optionality. If it uses AI, is it optional, transparent, and bring-your-own-model rather than locked in?
- No agents, no heavy footprint. Can it read the tenant through APIs without installing agents or a cloud service?
Three findings, end to end: what good auditing looks like
The difference between a score and an audit is what happens after the finding. Here are three real patterns from the Senserva demo tenant, walked from detection to fix.
A score-based tool moves your number when MFA coverage improves. An audit needs more: Senserva flags the specific account, ranks it Critical because Global Admin means total tenant takeover if the password leaks, maps it to SCuBA MS.AAD.3.1v1 and MCSB IM-6, and hands you the validated fix to review and apply. The next scan proves it closed. How the scanner works.
An app moves from Files.Read.Selected (a curated set of files) to Files.ReadWrite.All (every drive in the tenant) in one consent click. A point-in-time pass or fail misses the story; Senserva's change history shows exactly when the scope expanded and ranks the blast radius. This pattern is also a playable challenge in You v. Claude. Catching drift between scans.
A BYOD device last reported Compliant the same day its owner's account was disabled. Weeks later the account is re-enabled, and the Conditional Access policy still trusts the frozen compliance record. No single-domain tool sees this chain; Senserva correlates identities, devices, and policies in one graph, so the combination surfaces as one ranked finding with the remediation attached. How Senserva approaches the whole picture.
Where Senserva fits
Senserva is the dedicated posture and remediation layer. Run native Secure Score for Microsoft's baseline and ScubaGear or Maester for transparent pass/fail checks, then let Senserva rank what matters, map it to compliance, and hand you the validated fix across 650+ checks. It runs on Windows and Mac, reads the tenant through Microsoft Graph and related APIs with no agents and no cloud service, and AI is optional and bring-your-own-model via MCP, working with Claude or any AI.
Want to see it before you scan your own tenant? There is a free Advanced Microsoft 365 Security Simulator with no access to your tenant. See it in context on the Microsoft 365 security check page, or review compliance and frameworks.

Frequently asked
There is no single best tool for everyone. Native Microsoft tooling gives a baseline, open-source tools like ScubaGear and Maester give transparent pass/fail checks, and dedicated posture tools like Senserva add ranked findings, compliance mapping, and validated remediation. Choose based on coverage breadth, whether you need fixes and not just findings, and whether you manage multiple tenants.
Free and open-source tools such as CISA ScubaGear and Maester are useful and transparent, but they typically produce raw pass/fail output without ranked prioritization or validated remediation. They are a strong starting point and pair well with a dedicated posture tool that adds prioritization, compliance mapping, and fixes.
Yes. A thorough audit should cover identity in Entra ID plus Intune device management, Exchange and email security, SharePoint, OneDrive, Teams, and Purview. Senserva runs 650+ checks across the full Microsoft 365, Intune, Defender, Entra ID, and Purview stack.
Senserva needs no agents and no cloud service. It runs on Windows or Mac and reads your tenant through Microsoft Graph and related APIs. You can also try a free Advanced Microsoft 365 Security Simulator with no access to your tenant.
