Mailbox Health Auditor for MSPs
A B2B tool for managed service providers that audits every customer Microsoft 365 or Google Workspace inbox for authentication, sending limits, suspicious sign-ins, and deliverability posture across the entire tenant.
Managed service providers (MSPs) and IT consultancies serving SMB clients on M365/Workspace
- Multi-tenant dashboard scoring every inbox on SPF/DKIM/DMARC, MFA, and send-reputation
- Alerts on suspicious OAuth consents, impossible travel, and dormant risky accounts
- Bulk remediation playbooks (re-enable MFA, rotate keys, fix DNS)
- Quarterly compliance reports exportable for clients
Trending GitHub account-creation tools show how easily mailboxes can be abused; MSPs are increasingly responsible for tenant hygiene and need a single pane of glass.
Active MSP demand evidenced by r/msp threads on M365 scanners and Audit My Tenant actively onboarding MSPs in beta; the GitHub-trended Outlook/Hotmail batch account-creation tool (177 stars) confirms mailbox abuse is a real and rising concern driving this demand.Vulnerability Scanner for MSP's : r/msp ↗Audit My Tenant — M365 Security Compliance Scanner ↗
Market already has multiple direct and adjacent competitors: Audit My Tenant (1,554 rules, 14 frameworks), Augmentt (multi-tenant M365 MSP platform), Acronis Security Posture Management for M365, Sensible-Business-Solutions MSP-Audit-Tool on GitHub, and Microsoft's own Defender for Cloud Apps SSPM — leaving limited whitespace for a generic M365 audit SaaS.Pricing — Audit My Tenant M365 Security Scanner ↗Microsoft 365 Security & Management for MSPs | Multi-Tenant Platform ↗Acronis Security Posture Management for Microsoft 365 ↗Sensible-Business-Solutions/MSP-Audit-Tool - GitHub ↗
Proven per-tenant pricing model: Audit My Tenant charges $39–$249/mo for SMB/MSP tiers ($149 base + $39/tenant for Enterprise), and incumbents like Augmentt monetise at similar mid-$100s/seat-monthly — but MSPs are notoriously price-sensitive and entry-tier competition (free GitHub tools) caps the realistic ARPU.Pricing — Audit My Tenant M365 Security Scanner ↗Microsoft 365 Security & Management for MSPs | Multi-Tenant Platform ↗
M365 and Google Workspace are entrenched productivity platforms with multi-year enterprise lock-in; mailbox/auth abuse and MSP-led tenant hygiene are durable, not trend-bound problems that ensure multi-year demand.Microsoft 365 Security Enterprise Plans| Microsoft Security ↗
Technically feasible via Microsoft Graph API and Google Workspace Admin SDK with delegated OAuth — proven buildable (Audit My Tenant, Sensible MSP-Audit-Tool shipped comparable products), though multi-tenant Azure AD app consent, throttling, and deliverability signal ingestion add nontrivial engineering.Sensible-Business-Solutions/MSP-Audit-Tool - GitHub ↗
