Connect only the company information an AI use case needs, and preserve the source system’s access boundaries. Before rollout, check repository permissions, confirm the exact AI plan and connector terms, restrict connected sources and egress, then test what people with different data rights can retrieve. An enterprise product label or vendor commitment is not a substitute for checking your own configuration.
What “adding context” means—and where exposure can happen
Context is company information an AI tool can use to answer a question: for example, approved procedures, financial policies, product documentation, or—if the use case calls for it—email and chat. Microsoft describes Microsoft 365 Copilot grounding responses in organizational content available through Microsoft Graph, including documents, email, calendars, chats, meetings, and contacts. The more relevant and well-governed the source material is, the more useful that context can be. Microsoft Learn: Data, Privacy, and Security for Microsoft Copilot
Exposure can occur when a connector makes information easier to find than it was in ordinary work, when an account or group has broader source access than intended, or when prompts, retrieved passages, or outputs are handled under terms the organization has not reviewed. A system that respects source permissions can still reveal information to a user who already has overly broad access. Retrieval controls therefore need to be paired with permission cleanup, data minimization, and testing.
Compare the actual service and connection, not just the vendor
The following distinctions reflect the cited product documentation; they are not a security ranking. “Not stated” means the cited page does not establish that point. Confirm all terms and behavior for the exact subscription, connector, and configuration you plan to deploy.
#1 Best Overall
| Option documented | Permission boundary described | Data use and administration described | Important qualification |
|---|---|---|---|
| Microsoft 365 Copilot | Microsoft says users see organizational data they have at least view permission for, and that Semantic Index honors identity-based access boundaries. | Microsoft says prompts, responses, and Graph data accessed through Copilot are not used to train foundation models. The enterprise data-protection page describes identity and permission controls, sensitivity labels, retention, auditing, encryption, and prompt-injection protection. | Specific protections and policies vary by subscription. Agents and connected services can have separate terms and privacy statements; review their permissions and data access. Privacy and permissions · Enterprise data protection |
| OpenAI Company Knowledge in ChatGPT | OpenAI says Company Knowledge respects connected-source permissions; a member can retrieve information they are already authorized to access through an individually authorized account or supported administrator-managed connection. | OpenAI says business workspace data is not used to train models by default and describes enterprise access management and retention controls. | Availability depends on eligibility, supported sources, admin configuration, account connection, and sync-region support. Residency and in-region processing options depend on product and customer eligibility; storage at rest and inference processing are distinct. Company Knowledge · Business data privacy, security, and compliance |
| Google Cloud Gemini Enterprise with VPC Service Controls | The cited documentation describes service perimeters and Access Context Manager for controlling access to Gemini Enterprise and connected enterprise data; it does not state a specific user-level retrieval-permission behavior. | The documentation describes controls over projects, ingress, data sources, and egress domains. Access levels can use device and operating-system, IP-address, or identity conditions. | When restricted by a perimeter, the Discovery Engine API is inaccessible from the public internet except as allowed by ingress rules. Existing data stores have limitations when a perimeter is newly enforced, and new data stores can be blocked until required sources and egress domains are permitted. Training, retention, and residency terms are not stated in this cited VPC documentation; verify them separately. Google Cloud: Secure your app with VPC Service Controls |
Use the table to identify questions for procurement and security review, not as a substitute for reading the applicable contract, admin documentation, and connector terms. In particular, distinguish what happens to prompts, retrieved passages, and generated outputs; verify retention, deletion, residency, and inference-processing options for the specific plan; and check which interactions administrators can audit.
Prepare the data and permissions before connecting anything
Define a narrow use case
Write down what users need the AI to answer and which source material is necessary. Start with a limited, read-only knowledge source when possible. Add email, chat, meetings, or action-taking connections only when the use case justifies their broader reach. For a finance team, an approved expense policy or close-process guide may be a narrower starting point than a broad mailbox or shared-drive connection.

Repair source access
Review permissions in the source system before enabling retrieval. Remove stale or overly broad groups, check external-sharing rules, verify that identity lifecycle processes remove access when roles change, and confirm that sensitivity labels and restricted-use rights are current. Microsoft says its Copilot protections can apply existing identity, permission, sensitivity-label, retention, and audit controls, with availability varying by subscription; these controls do not correct an incorrect source permission. Microsoft Learn: Enterprise data protection in Microsoft Copilot and Microsoft Copilot Chat
Approve the precise connector and terms
For the intended plan and source integration, record who can enable it, what it can read, whether it syncs or retrieves on demand, what data is sent for inference, and how access changes or revocation are handled. Check the provider’s training-use commitment, retention and deletion controls, residency and processing options, audit coverage, and admin roles. Do not assume one product’s business-data terms also apply to a separate agent, third-party app, or connected service.

- Limit the scope. Select the smallest source set, user population, and connector permissions that can support the pilot. Prefer read-only access unless the workflow requires actions.
- Restrict access paths. Use identity-aware source access, approved-app controls, and network restrictions where available. Allowlist only necessary sources and egress destinations. A network perimeter constrains paths; it does not replace authorization checks in the source system.
- Review each agent and app. Inspect its requested permissions, data access, terms, and administrator controls individually. A connected tool may have different practices from the main AI workspace.
- Set operational ownership. Assign owners for connector approval, group and role changes, retention settings, audit review, and incident response. Ensure the team knows how to disable a connection and investigate an unexpected answer.
Google Cloud’s VPC Service Controls documentation illustrates why network restrictions require configuration rather than a simple on/off assumption: a perimeter may block public API access, require explicit ingress and egress allowances, and constrain creation of new data stores until sources and domains are permitted.

Test with users who should—and should not—see the information
Test the deployed tenant and connected sources using representative accounts, not only an administrator account. Include adversarial prompts and content designed to expose mistakes, but treat a successful test as evidence about the tested cases, not proof that all leakage risk is eliminated.
Rank #4
- A user who should have access to a document, and a user who should not.
- A shared item, an externally shared item, and content in a group whose membership recently changed.
- A user whose permission was revoked, to check whether access is actually withdrawn across the connection and any sync or cache behavior.
- Sensitive-labeled or restricted-use content, with checks for both answer text and citations.
- A document containing instructions that try to redirect the AI or extract unrelated data.
- Prompts that request information across source boundaries, plus downstream actions, exports, and logs where applicable.
Inspect the returned answer, citations, retrieved sources, access-denied behavior, audit events, and any downstream action. Confirm that a citation does not expose a title or excerpt that the user cannot otherwise access. Document the account, permissions, query, expected result, and observed result so a failed check can be reproduced and fixed.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Monitor the connection after launch
Permissions, connectors, provider settings, and company data change over time. Periodically review connector scopes and owners, access groups, agent approvals, retention and residency settings, audit events, and incident procedures. Repeat the role-based tests after major configuration changes, source migrations, or permission-model changes. Disable a connection if its scope or data handling can no longer be verified, then re-enable it only after the issue is resolved.
