Information Protection Review

When this service becomes necessary

• The organisation is preparing to deploy Microsoft 365 Copilot and needs to confirm that information protection is adequate before enabling it.
• A data breach, privacy incident, or audit finding has raised questions about how sensitive information is being handled within Microsoft 365.
• Sensitivity labelling has been deployed but adoption is inconsistent and it is unclear whether sensitive data is actually being protected.
• Oversharing risk in SharePoint, Teams, or OneDrive has been raised as a concern but has not been assessed or quantified.
• Regulatory or compliance obligations require evidence that sensitive data is identified, classified, and protected appropriately.
• Microsoft Purview has been licensed but the configuration does not reflect the organisation's current information classification requirements.

What Evoltra reviews

• Sensitivity label taxonomy: whether labels reflect the organisation's information classification policy and are fit for purpose
• Label adoption: coverage, consistency, and whether auto-labelling is configured for high-sensitivity content types
• Data loss prevention policies: whether DLP rules are configured for the organisation's sensitive data types and risk channels
• Oversharing exposure: SharePoint sites, Teams channels, and OneDrive with excessive external or internal sharing
• Information lifecycle: retention policies, records management configuration, and whether content is being retained and disposed of appropriately
• Guest access: external user access to sensitive content and whether controls are adequate
• Purview configuration: whether the technical implementation of Microsoft Purview reflects the organisation's governance requirements
• Policy and process gaps: where technical controls exist without supporting policy, or policy exists without technical enforcement

How the engagement works

1. 1

   Configuration and policy review

   Review the current Microsoft Purview configuration: sensitivity labels, DLP policies, retention policies, and related settings. Compare configuration against the organisation's information classification policy and compliance obligations.

2. 2

   Oversharing and access review

   Assess SharePoint, Teams, and OneDrive for oversharing exposure: sites and channels with broad internal or external sharing, guest access that is not governed, and sensitive content in locations accessible to unintended audiences.

3. 3

   Label adoption assessment

   Review label adoption rates, coverage across content types, and whether auto-labelling is in place for sensitive content that should not depend on user decisions. Identify where the labelling programme is working and where gaps remain.

4. 4

   Findings and remediation plan

   Deliver a written assessment of the current information protection posture, with findings graded by severity and a remediation plan that sequences actions by risk reduction priority. Technical recommendations are paired with the governance and policy changes required to make them effective.

Who this is for

Organisations operating Microsoft 365 that need an independent view of how well sensitive information is being protected. Particularly relevant before a Microsoft 365 Copilot deployment, after a privacy or security incident, in response to a regulatory or audit requirement, or where the organisation knows its information protection is not where it should be but lacks the internal capacity to assess the gap and design the remediation.
