TL;DR: Australian financial organisations face rising audit and control risk in Microsoft 365, AvePoint reports, because data sprawl, oversharing and weak visibility make governance hard to prove under APRA CPS 220 and CPG 235. Microsoft 365 oversight now needs current evidence on data, permissions and ownership, not just policy language.
Editorial analysis by NHI Mgmt Group, based on content published by AvePoint: “Closing the Visibility Gap: How to Identify and Prioritise Data Risks in Microsoft 365”.
By the numbers:
- 75.1% of organisations have experienced at least one data security incident involving overshared sensitive data.
- Almost 80% of organisations manage 1 PB or more of data.
- Data growth is expected to almost double from 22.5% to 40% over just a two-year window.
Key questions
Q: What happens when sensitive data is spread across collaboration tools without visibility?
A: The organisation loses the ability to prioritise risk, validate access and answer auditor questions with confidence.
Q: How do dashboards and heatmaps improve risk management in cloud collaboration environments?
A: They translate raw permission and content data into a ranked view of exposure, which helps teams focus on the most material issues first.
Q: How should financial organisations govern Microsoft 365 data exposure for audit readiness?
A: They should treat content visibility, permission visibility and evidence generation as one control system.
Practitioner guidance
- Implement continuous visibility for shared content and permissions Track where sensitive information resides across Teams, SharePoint and OneDrive, then link that inventory to owners and access paths so governance can be updated as the environment changes.
- Build risk heatmaps for misclassified data and risky permissions Use heatmaps to surface externally shared content, inactive accounts with access and mislabelled information so remediation effort is focused on the highest-impact exposures.
- Automate compliance evidence generation Pull reporting evidence directly from the systems that control sharing, permissions and monitoring so audit requests can be answered without manual reconstruction.
Bottom line: The central problem is not Microsoft 365 itself but the loss of visibility across data, permissions and ownership as collaboration scales.

Visibility debt is now a governance problem, not an operational inconvenience. When organisations cannot see where sensitive information sits or who can reach it, every downstream control becomes weaker. That is especially true in cloud collaboration environments where access expands faster than manual oversight. For identity and data governance teams, the practical conclusion is that inventory and entitlement visibility must be treated as foundational control inputs, not post-event evidence.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- By 2029, 40% of enterprises that successfully implement zero trust within cloud service provider environments will rely on the advanced visibility and control capabilities offered by CNAPP solutions.
A question worth separating out:
Q: Why do access reviews struggle when collaboration permissions change quickly?
A: Because reviews are usually periodic, while collaboration permissions can change continuously across shared workspaces and external links. By the time a review runs, the access state may already be outdated. Continuous visibility and automated monitoring are needed so the control operates at the speed of the environment rather than after it has moved on.
