Two strong tools answering different questions. Here is how the coverage maps out.
| Capability | 365 Security Assessment | AppOmni |
|---|---|---|
| M365 rule depth | 24,000+ rules across M365 surfaces | Subset of 100+ app connectors |
| Azure resource-plane coverage | Not the core focus | |
| MITRE ATT&CK mapping | Not advertised publicly | |
| Compliance framework count | 10 frameworks | ~6 referenced publicly |
| Agentless / read-only | ||
| Time to first results | Same-day after consent | Hours to deploy; sales cycle to onboard |
| MSP multi-tenant | Enterprise-direct posture | |
| Public pricing / free tier |
AppOmni is a genuine leader at what it does: giving security teams visibility across a heterogeneous SaaS portfolio. That breadth is valuable if your risk surface spans Salesforce, Workday, ServiceNow, and dozens of others.
365 Security Assessment is built for a different question: how deeply can you inspect the Microsoft estate? When M365 and Azure are your primary attack surface, you need thousands of rules per module — Exchange Online, Entra ID, Conditional Access, SharePoint, Teams, Intune, Azure RBAC, Key Vault, Defender configurations — not a platform-agnostic layer that visits each app briefly.
The two tools are not competing for the same job. Organizations running large Salesforce and Workday estates alongside M365 often carry both: AppOmni for breadth across the SaaS portfolio, 365SA for depth on the Microsoft surface.
Exchange Online
Anti-phishing, transport rules, mail flow, DKIM/DMARC, connector hygiene — inspected at rule-by-rule granularity.
Entra ID & Conditional Access
Every CA policy, MFA posture, guest permissions, legacy auth status, PIM gap — not a summary count.
Azure Resource Plane
RBAC sprawl, Key Vault access policies, NSG rules, Defender coverage, storage exposure — natively collected and audited.
Intune & Device Compliance
Compliance policy gaps, encryption enforcement, conditional access device state — all surfaced in the same assessment.
Plus MITRE ATT&CK mapping on critical findings — so every high-severity issue links to a real adversary technique, not just a policy number.
Every finding in 365 Security Assessment traces back to specific control points across ten compliance frameworks. When an auditor asks for evidence of your HIPAA safeguards or FedRAMP controls, the report is the answer — not a dashboard screenshot.
On critical findings, MITRE ATT&CK technique IDs are mapped alongside the framework citations. This connects posture gaps to real adversary playbooks, giving remediation teams context beyond "this setting is misconfigured."
AppOmni references six compliance frameworks publicly. If your regulatory footprint requires ten — particularly CMMC, FedRAMP, or HITRUST alongside the others — that gap matters at audit time.
AppOmni's buying motion is enterprise sales-led with custom scoping. That is appropriate for a platform deployed across 100+ SaaS apps with complex organizational requirements — but it means weeks before a security team sees their first finding.
365 Security Assessment offers a free tier and self-serve onboarding. A tenant owner can consent today and receive an initial report covering their full M365 and Azure posture before end of business. No procurement cycle, no scoping call, no waiting.
For MSPs managing dozens of client tenants, this per-tenant economics model also means no per-app licensing negotiation. Each tenant gets its own full assessment at predictable cost.
