PAA vs 365 Security Assessment
Both look at Microsoft 365. One counts misconfigurations. The other tells you what to change.
365 Security Assessment is an M365 posture scanner — built to count misconfigurations across your tenant and hand an auditor a stack of evidence. If your single job is a deep settings-level M365 audit against US compliance frameworks, it’s built for exactly that. PAA answers a bigger question: is your Azure + M365 architecture actually sound — and what do you change? Every finding is checked by a second AI pass before you see it, it runs continuously rather than once, your data stays in the EU, and it costs a fraction of theirs.
| Aspect | PAA | 365 Security Assessment |
|---|---|---|
| What it is | Always-on architecture intelligence | M365 posture scanning (SSPM) |
| Lens | All 5 Well-Architected pillars | Security posture only |
| Scope | Azure + M365 + Zero Trust | Microsoft 365 (deep) + Azure |
| Findings | 800+ checks, each adversarially verified | “12,000+ signals” (raw count) |
| Cadence | Continuous + drift detection | Scan-based (one-off or weekly) |
| Remediation | Terraform / Bicep generated | Copy-paste PowerShell |
| Data residency | EU | Not stated |
| Pricing | From €99/day · €799/mo | $9,997 one-time / $2,497–4,997/mo* |
| Maturity | Live product | Pre-GA / early access |
*Their early-access pricing; public list prices are higher. Both tools are read-only — neither does runtime threat detection (that’s your XDR’s job). Figures from their public site; verify there.
Where 365 Security Assessment is genuinely strong
Raw Microsoft 365 settings depth — they market thousands of Exchange-specific rules — and a long list of US compliance frameworks (FedRAMP, CMMC, HITRUST). If you’re a US-centric, M365-heavy organisation chasing those certifications specifically, that breadth is real. We’d rather tell you that than pretend otherwise.
Depth isn’t a signal count
Their headline is a number: 12,000+ signals. A 12,000-signal scan that surfaces 400 findings, eighty of them noise, doesn’t make you more secure — it makes you spend a week triaging. PAA optimises the other variable. Every finding survives a three-pass adversarial review before it reaches your report, so what you get is fewer, verified, ranked findings with the architectural reasoning attached. More signals, more triage. Verified findings, more truth.
PAA looks at the layer they don’t
Architecture. Is the design itself sound against the Well-Architected and Cloud Adoption Frameworks? Where’s the wasted spend? Which over-privileged identity is a structural problem, not just a flagged setting? A scanner can tell you a box is unchecked. It can’t tell you the building is leaning — and it can’t hand you the Terraform or Bicep to straighten it.
The honest summary
If you want the deepest possible US-compliance M365 settings sweep and budget isn’t a constraint, they’re a reasonable choice. If you’re a Microsoft-cloud team in Europe that needs to know your architecture is sound and stays sound — with EU data residency, verified findings, and a €99 way to start — that’s PAA.
Lead with 365 Security Assessment when…
You’re US-centric and Microsoft-365-heavy, chasing FedRAMP / CMMC / HITRUST specifically, you want the deepest settings-level M365 sweep, and enterprise pricing isn’t a constraint.
Lead with PAA when…
You need your Azure + M365 architecture to be sound and stay sound — NIS2 readiness, EU data residency, verified findings over a raw signal count, remediation code, and a €99 way to start. Or you’re an MSP who wants to carry posture across your whole book, white-label, at margin.
Questions
Is PAA just another M365 security posture tool (SSPM)?
No. 365 Security Assessment is an SSPM — it scans your Microsoft 365 tenant and counts misconfigurations. PAA is architecture intelligence: it reviews whether your whole Azure + M365 + Zero Trust environment is built right across the Well-Architected pillars, maps it to frameworks, and generates the remediation code. Posture scanning is one part of what PAA does, not the whole of it.
365 Security Assessment advertises 12,000+ signals. PAA lists 800+ checks — isn’t that less?
Fewer signals, not less truth. PAA runs 800+ Microsoft-aligned checks and then puts every finding through a three-pass adversarial review — one AI agent proposes it, others try to refute it — before it reaches your report. You get verified, ranked findings with the reasoning attached, not a 12,000-row export to triage. More signals usually means more noise, not more security.
We’re an MSP — which makes more sense?
PAA is built for resale: white-label reports, a per-console seat, and child-tenant pricing designed for margin across a whole book of tenants. Their model is a 20% referral on someone else’s invoice. If you’re carrying NIS2 across multiple tenants, the economics aren’t close.
Do either of these replace Microsoft Defender or my XDR?
No. Both are read-only — neither does runtime threat detection. They tell you whether your environment is built and configured well; Defender/XDR watches it at runtime. Most teams run both. See our Defender for Cloud comparison.
Don’t take the comparison on faith. Run it.
