Most organisations start looking at a governance platform in the same week: someone runs a report, discovers four hundred Teams nobody owns, and asks how it got that bad. Orchestry, AvePoint, Powell and the others all sell a convincing answer, and they are genuinely good products. The question worth asking first is which part of the problem they actually solve.
What the platforms do well
Provisioning is the strongest case. A request form, a template, a naming convention and an approval step, applied consistently, is worth real money once people are creating workspaces faster than anyone can watch. Lifecycle is the second: ownership checks, expiry, archival, guest reviews on a schedule. Reporting is the third, and it is the one people underrate, because a dashboard your leadership will actually open changes conversations that spreadsheets never did.
At scale, that is a straightforward business case. Several administrators, dozens of new workspaces a month, regulated retention, a merger to absorb: buy the platform.
What they do not fix
A governance platform automates a policy. It does not write one. If there is no decision on record about who may create a Team, what happens to it when the project ends, or who owns the data inside it, the platform will apply that absence consistently and at speed. The sprawl becomes tidier and better labelled. It does not become smaller.
That is the failure worth naming, because it is expensive. Per-user licensing on top of Microsoft 365 is a permanent line in the budget, and it is very hard to justify twelve months later if the underlying questions were never settled.
What Microsoft 365 already gives you
More than most tenants use. Sensitivity labels can apply container settings to sites and Teams. Sharing links can be forced to expire. Group expiration policies exist and can be turned on this afternoon. Access reviews cover guests properly if you hold Entra ID P2, which many organisations already do without realising. None of it is as polished as a dedicated product, and all of it is free at the point of use.
The cheaper first move
Write the policy first, in one page: who creates, who owns, what expires, what is reviewed. Turn on the native controls that enforce the easy parts. Then measure for a quarter. If the gap between the policy and the tenant is still wide, you now have a specific, defensible case for a platform, and you will configure it far better for having done the thinking.
If you would rather have someone else find the gap, our Microsoft 365 security assessment covers exactly this ground.
