No. Copilot only uses content the signed-in user already has permission to open. The risk is that many organisations have shared content far more widely than intended. Copilot makes that content much easier to find, so oversharing that went unnoticed for years can suddenly appear in an answer. Fixing permissions is the real solution.

No. Microsoft's own guidance is to contain high-risk sites first, then remediate. Controls such as Restricted Content Discovery keep chosen sites out of Copilot and organisation-wide search while permissions are reviewed. That lets you start with lower-risk teams while clean-up continues. These controls are temporary and do not replace proper permission fixes.

We mainly use Microsoft Purview, including Data Security Posture Management, sensitivity labels, data loss prevention and auditing, together with SharePoint Advanced Management, which Microsoft includes with Copilot licences. Some advanced Purview features need Microsoft 365 E5 or add-ons, so we confirm what your licences already cover before recommending anything new.

This service fixes the data layer: who can reach what, and how sensitive content is labelled and protected. AI governance sets policy, ownership and oversight across all AI use. An AI security audit tests deployed Copilots, agents and apps against attacks such as prompt injection. Many organisations do all three, usually starting with data readiness.

Very little, if planned well. Assessments run in the background. Containment hides content from Copilot and search without removing anyone's existing access. Permission changes are agreed with site owners first and communicated in advance, and labelling can start in recommendation mode before it is enforced, so people have time to adjust.

Oversharing returns as people create sites, add guests and share links. We set up recurring data risk assessments, site access reviews, inactive and ownerless site policies, default labels and alerts for risky sharing. Your team gets a simple monthly routine, and ongoing monitoring can be added if you would prefer us to keep an eye on it.

Yes. We help organisations across Australia, including Sydney, Melbourne, Adelaide and Wollongong, prepare their Microsoft 365 data for Copilot. Assessments run remotely in your tenant, and workshops with site owners can be on-site or online, backed by our wider Microsoft security and AI team. 

Overshared personal information is a privacy risk with or without Copilot. Our assessment flags where personal information is exposed too widely, which supports your obligations under the Privacy Act 1988 and the Australian Privacy Principles. We flag where legal advice is needed. Final compliance depends on your environment, data and legal obligations.
