Protect Microsoft 365 data before scaling generative AI.
Microsoft 365 Copilot can surface information that users already have permission to access. Oversharing, excessive permissions and inconsistent data controls can therefore create unintended exposure when generative AI is introduced.
Organisations also need visibility of sensitive information and the unmanaged use of third-party AI tools before they can make informed security and governance decisions.
Arinco’s Microsoft Data Security Assessment reviews how organisational data is stored, accessed and shared across Microsoft 365. It uses Microsoft security tooling and AI-assisted analysis where appropriate to identify data exposure, permissions and risks associated with generative AI.
Arinco security specialists validate the findings and provide prioritised guidance to strengthen data governance, reduce exposure and prepare the organisation for responsible adoption of Microsoft 365 Copilot and other AI solutions.

Microsoft 365 Copilot uses the access permissions already applied within an organisation’s Microsoft 365 environment. If users have unnecessary access or information has been overshared, Copilot may make that information easier to find. Reviewing permissions, sharing practices and data controls is an important part of preparing for deployment.
Organisations can use Microsoft security and compliance tools to assess permissions, sharing activity, sensitive information and other indicators of data exposure across services such as SharePoint Online, Teams and Exchange Online. Findings should be validated and prioritised according to business risk.
Organisations should review data exposure, user permissions, external sharing, sensitive information controls, insider risk and existing governance. They should also consider how employees use third-party AI tools and establish clear ownership for ongoing monitoring and improvement.
