Microsoft Audit Management Software

A purpose-built audit management platform gives you workflow enforcement — a control cannot be marked tested without an attached workpaper, a finding cannot close without sign-off. Microsoft 365 gives you the building blocks (SharePoint document libraries, Lists for control inventories, Planner or Power Automate for workflow, Power BI for reporting) but none of the enforcement is native; it has to be configured. The difference matters most in walkthrough documentation and evidence retention: a Lists-based control inventory with a status column does not by itself prevent someone from marking a control 'tested' without ever attaching a workpaper, the way a dedicated tool's required-field logic would.

Where Microsoft 365 genuinely competes with dedicated GRC tooling is evidence sourcing, not workflow enforcement. Purview's unified audit log, Entra ID sign-in logs, and Power Platform's flow run history are primary evidence sources regardless of which audit management tool sits on top of them — a control tested in AuditBoard still needs the underlying Entra ID access review export as its evidence artifact. Teams that run audit management natively in Microsoft 365 are, in effect, skipping the layer that would otherwise pull that evidence in automatically, which means someone has to manually retrieve and attach it each testing cycle.

A SharePoint- or Purview-records-management-based workpaper repository needs three things a plain document library does not provide out of the box: version history that cannot be altered after sign-off, a retention label preventing deletion before the audit cycle and any look-back period close, and access restricted so the control owner cannot also be the reviewer who approves the workpaper. Microsoft Purview Records Management can apply immutable retention labels to a document library, and SharePoint's built-in versioning satisfies the 'cannot be silently altered' requirement, but both require deliberate configuration — the default SharePoint site does neither.

The recurring gap in Microsoft-native audit programmes is retesting evidence for automated controls. A manual control's workpaper is a screenshot and a sign-off; an automated control — say, an Entra ID Conditional Access policy or a Power Automate approval flow — needs evidence that the control's configuration has not silently changed since it was last tested. That requires pulling a configuration export (a Conditional Access policy JSON, a Power Platform DLP policy) at each testing interval and diffing it against the prior period, which is a task teams building on Microsoft 365 alone often skip until an auditor specifically asks for change evidence on an automated control.

Power BI connected to a Lists- or Dataverse-based control inventory can produce a real-time SOX control-status dashboard — tested, in remediation, overdue — that internal audit leadership and the audit committee can review without waiting for a quarterly export. This is a genuine advantage of the Microsoft-native approach: most dedicated GRC platforms charge per seat for dashboard access, while a Power BI report can be shared broadly within the existing Microsoft 365 license.

The limit is that Power BI reports on what is entered into the underlying data source; it does not validate the entry. A control marked 'tested — no exceptions' in Dataverse with no attached workpaper will show green on the dashboard exactly the same as one with a complete, reviewed workpaper. Organizations that rely on Power BI for control-status reporting without a workflow layer enforcing evidence attachment are, in practice, trusting the control owner's self-report, which is a weaker position than a dedicated tool's required-attachment workflow going into an external audit walkthrough.
