Built for the CISO or compliance officer whose business has bought Microsoft 365 Copilot and is about to discover that Copilot surfaces every document a user already had permission to open. This engagement will eliminate the oversharing that turns a Copilot rollout into a data incident, before the first license is assigned.

Who this is for

Organizations that have committed to Microsoft 365 Copilot and have a security or compliance function that has raised a hand. The CISO or compliance officer is the buyer; the pressure comes from a board or business sponsor who wants Copilot live this quarter. The specific fear is well founded: Copilot respects existing permissions exactly, so a decade of 'share with everyone in the organization' links becomes a search interface over your own HR and finance content on day one.

What we deliver

A tenant-wide oversharing assessment using Microsoft Purview and SharePoint Advanced Management: every site, library, and link that grants organization-wide or anonymous access, ranked by the sensitivity of what sits behind it.
Remediation of the high-risk findings, covering site access review, restricted access control policies on the sites that need them, and expiry on existing anonymous sharing links.
Microsoft Purview sensitivity labels applied to the content categories that must never reach a Copilot response, with DLP policies configured for the generative AI location so labeled content is excluded.
Copilot-specific audit and reporting: Purview audit configured for Copilot interactions, a Communication Compliance policy for prompt and response review, and a written go-live readiness statement your compliance function can sign.

Outcomes our customers see

A 5,000-seat customer reduced organization-wide-shared SharePoint sites from 412 to 34, a 92 percent reduction, in 45 days. One assessment found 27,000 active anonymous sharing links, 3,100 of them on content carrying a confidential label, all expired or revoked 21 days before Copilot go-live. Customers completing this engagement have reached Copilot go-live an average of 60 days sooner than those that started remediation after the first licenses were assigned.

How this compares

Nearly every Copilot readiness offer is an adoption and change-management engagement with a security paragraph at the end. This one is the inverse: it exists solely to close the data exposure that Copilot makes searchable, and it is designed to run before licenses are assigned rather than after the first incident. Compared with a generic Purview deployment, the scope is deliberately narrow, targeting the content and sharing patterns Copilot actually reaches.

Architecture and Microsoft alignment

Assessment and remediation run through Microsoft Purview, SharePoint Advanced Management, and Microsoft Graph. Sensitivity labels and DLP policies are configured in Purview with the generative AI location in scope, so labeled content is excluded from Copilot grounding. Restricted Access Control and site access reviews are applied in SharePoint. Copilot interaction audit flows into Purview Audit and, where licensed, Communication Compliance. Microsoft Entra ID group membership is reviewed as the underlying permission source. Aligned to the Microsoft solution plays Protect Cloud AI Platform and Apps and Secure AI Productivity.

Plans

Plans, prices, and full scope per plan are on the Plans tab of this listing.

Prerequisites

Microsoft 365 E5 or the E5 Compliance add-on for full Purview capability, SharePoint Advanced Management for restricted access control and reporting, Global Administrator and Compliance Administrator consent, and a named content owner per business unit for the access review decisions.

Limitations

This engagement secures the data plane Copilot reads. It does not include Copilot adoption, prompt training, or change management, which are separate offers. Content held outside Microsoft 365, including on-premises file shares and third-party document platforms, is identified as a risk but not remediated here. Labeling decisions on ambiguous content require a customer data owner and cannot be made on your behalf.
