TL;DR: The real issue is whether standardized tenant scanning, ranking, and remediation can improve governance without obscuring review boundaries, according to Senserva, which is offering a flat-rate Microsoft 365 security package for MSPs covering up to 50 tenants, 100 users per tenant, and 650+ checks with AI-assisted remediation, pricing that shifts multi-tenant security from seat-based budgeting to fixed-cost operations.
NHIMG editorial — what this means for NHI practitioners
By the numbers:
- Up to 50 tenants under one subscription.
- 650+ Microsoft 365, Intune, Defender, and Entra ID security checks.
- The price is $600 per month, or $6,500 per year.
Questions worth separating out
Q: How should MSPs govern Microsoft 365 security across multiple tenants?
A: MSPs should use one control framework, one prioritisation model, and one closure workflow across all tenants.
Q: Why does flat-rate pricing matter in multi-tenant security operations?
A: Flat-rate pricing matters because per-seat or per-tier licensing can distort how MSPs deploy controls across tenants.
Q: What do teams get wrong about AI-assisted remediation in Microsoft environments?
A: Teams often assume AI-assisted remediation is complete when a recommendation is generated.
Practitioner guidance
- Standardise tenant scoring before expanding coverage Define one prioritisation model for Microsoft 365, Intune, Defender, and Entra ID findings so every tenant is reviewed against the same severity logic and remediation order.
- Require closure evidence on the next scan Do not treat a remediation task as complete until the next scan confirms the configuration or exposure has changed and the gap no longer appears in reporting.
- Map findings to customer-facing control language Translate each tenant finding into a framework-aligned control narrative so service reviews and audit conversations use the same evidence trail across the book of business.

Flat-rate Microsoft 365 tenant security: what does it change for MSPs?

Flat-rate multi-tenant security pricing changes the governance model, not just the commercial model. MSPs do not need another per-seat cost calculator as much as they need a way to apply the same Microsoft 365 control logic across many customer tenants. Once the number of tenants grows, the real failure mode is inconsistency in review, prioritisation, and evidence collection. The implication is that service design matters as much as tool selection.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is why review consistency matters as much as scan coverage.
A question worth separating out:
Q: How can organisations tell whether tenant security reviews are actually working?
A: They should look for repeatable closure evidence, stable severity ranking, and consistent handling of exceptions across every tenant. If the same issue is classified differently from tenant to tenant, the programme is producing noise rather than governance. Consistency is the signal that the operating model is working.
