The hard part of Microsoft licensing
is the server room.

CerteroX works out what you owe Microsoft for servers, access rights and Microsoft 365, checks it against what you have bought, and shows where you are paying for more than you use.

In short

Microsoft’s biggest costs sit in the server room.

Counting desktop licences is straightforward. Server and access licensing depends on how your systems are built and who can reach them, which no purchase record shows. CerteroX models that for you and compares it with Microsoft’s own statement of what you have bought.

  • Cost

    Use the rights you already paid for.

    See unused Microsoft 365 licences and the entitlements you are not claiming, before buying more.

  • Risk

    A position that holds up to Microsoft.

    Server licensing reflects how your systems really run, and is reconciled to Microsoft’s own licence statement.

  • Effort

    No more annual true-up scramble.

    The position is kept up to date as systems change, so the true-up becomes a review rather than a project.

See the statement reconciled
and the server room modelled.

An MLS import reconciled against the agreements, core and CAL licensing modelled across a cluster, and the idle Microsoft 365 seats on the same asset record. Say whether servers, CALs or subscription hurts most and the session leads with it.

Come with the true-up you are dreading. That is the conversation worth having.
