CIS coverage for Microsoft 365

580 pages of recommendations. 160 items to verify. Nine admin consoles. That is what the Center for Internet Security asks you to verify for a Microsoft 365 tenant to count as properly hardened. Tenovia delivers that CIS Microsoft 365 coverage for you, and runs no script on your estate.

CIS Microsoft 365 coverage, in plain terms

The CIS Microsoft 365 Foundations Benchmark v7.0.0, released on 20 May 2026, is the most widely used hardening framework for Microsoft 365. In total, the document runs to 628 pages, and 580 of those are recommendations proper. It is not a vendor opinion. Expert consensus produces it, and compliance teams therefore use it as the baseline for NIS2, DORA and ISO/IEC 27001 work.

The problem nobody spells out

In practice, checking those 160 items by hand means opening nine consoles, walking through hundreds of screens, and starting again from scratch at the next audit. Count it in weeks. Moreover, at the end you hold a finding nobody can replay.

However, the usual alternative is worse. It has the client teams run a PowerShell script kit. That means getting authorisation to execute code on a production environment, tying up an administrator, handling failures, and hoping nobody altered the script along the way.

What Tenovia does

• No script run on your estate. An application registered in your directory, read-only. Your teams therefore run nothing, install nothing, maintain nothing.
• No write permission. Tenovia is technically unable to change anything in your tenant. In addition, Tenovia provides the exact permission list before onboarding, and your security team can therefore review it.
• A dated, defensible finding. Every gap retains the raw data behind it: object, property, value, collection date. As a result, an external auditor can retrace the path.
• Reproducible. The second audit reads as a difference: what was fixed, what regressed, what did not move. You therefore measure configuration drift instead of absorbing it.

The 20 items no interface exposes

Of the 160 recommendations, Tenovia measures 140 automatically and treats 20 as guided checks. These are not oversights. In fact, no interface exposes them, for example defining two emergency access accounts or monitoring their activity.

No tool automates them, simply because the platform exposes nothing to read. Tenovia therefore asks precise questions instead, records the expected answer, and folds them into the same report. As a result, you get all 160, not 140 and a gap.

What you receive

• An audit report by domain, with the compliance score and the original wording of each CIS control
• The technical evidence behind every finding, time-stamped
• A prioritised remediation plan ranked by severity, effort and gain
• Finally, the regulatory mapping of every gap to NIS2, DORA, ISO/IEC 27001 or the GDPR

Who it is for

Firstly, audit firms industrialise the technical part of their engagements with this CIS Microsoft 365 coverage, and therefore deliver a consistent finding whichever auditor is assigned. Secondly, security teams measure drift between two runs. Finally, managed service providers evidence the quality of the configuration they deliver, and catch regressions before their client does.
