An employee connects an AI tool to help write one document. The task is narrow. The permission request might not be.
Depending on the access granted, that tool could be able to read other documents the employee can access—not just the file they had in mind. Before connecting an AI assistant to Google Drive, OneDrive or SharePoint, ask a more useful question than whether the tool is approved: what data can this particular connection reach, and what actions can it take?
Blue Lantern Security's AI access posture checks help organizations review AI app access through their Google and Azure integrations. That visibility gives administrators a starting point for deciding which connections to keep, restrict or revoke.
A local-looking assistant can still process data elsewhere
An AI tool can appear inside a desktop application or familiar document editor while sending information to a remote service for processing. Where the interface runs does not tell you where the model runs.
That matters when a task includes personal information, customer records, internal documents or API keys. Review the provider's processing, retention and data-use terms, as well as the permissions granted to the app. These answer different questions: permissions describe what a connection can access; the service's architecture and terms describe how data may be handled.
An externally operated AI service is a third party. An internally hosted agent may have a different processing arrangement, but still needs appropriate access boundaries. In either case, a mistaken instruction or unwanted action can have wider consequences when the agent has more permissions than its task requires.
Check the permission, not just the task description
“Help me write a document” does not specify how much access an app needs. The authorization screen and granted permissions are where that boundary is defined.
Google Drive, for example, distinguishes per-file access through drive.file from broader access such as drive.readonly, which permits viewing and downloading the user's Drive files. Connecting an app does not automatically grant access to every document; the actual scopes and account access matter. Google Drive permission scopes.
In Microsoft environments, also distinguish access delegated by a signed-in user from application permissions used without a signed-in user. The resources available depend on the permission type, consent and any applicable resource restrictions. Microsoft's agent access guidance.
| Question | Why it matters |
|---|---|
| Which app received access? | A familiar brand name is not enough to identify the particular application and publisher |
| What can it read or change? | Reading documents, modifying them and taking other actions carry different consequences |
| How broad is that access? | Access to selected files is different from broad account or organizational access |
| Who owns the connection? | Someone should be responsible for its purpose and continued use |
| Is the access still needed? | A completed experiment can leave behind a connection with ongoing permissions |
What Blue Lantern Security helps you review
Blue Lantern Security brings attention to AI app permissions in connected Google and Azure environments:
| Environment | What the checks help surface | What to review next |
|---|---|---|
| AI apps granted access to Drive and the permissions they received | Whether that access matches the documents and work the app is intended to support | |
| Azure / Microsoft Entra | Access associated with AI applications and unverified-app findings | The permission scope, publisher context and business reason for the connection |
How to enable the checks
In Blue Lantern Security, open the settings for your Outlook or Gmail organization integration, enable Daily AI exposure scan, and save the settings. The enabled checks run once daily, with results in the Monitoring Hub under AI Exposure.
The scan reads app identities and granted permission scopes, rather than message or file contents. Your administrator must also grant the required integration permissions: Application.Read.All with admin consent for Outlook, or the admin.directory.user.security scope on the existing domain-wide delegation grant for Gmail. Follow the permission instructions shown in your integration settings.
Review the findings to see which AI connections deserve attention. Because this is a daily check, a new permission grant may not appear until the next run.
Use those findings to identify tools that have unnecessary access to sensitive information. Administrators can then review and revoke inappropriate grants in the relevant platform, or replace a connection with a narrower supported access arrangement.
This is an access review. A permission grant does not establish that an app has read every available file or sent its contents elsewhere. Those questions require additional activity evidence. Likewise, a permissions inventory alone will not reveal every instance of someone pasting sensitive text into a chatbot.
Treat an unverified publisher as a review signal
Publisher verification helps establish the publisher's identity. It is not a security assessment of everything an app does. An unverified publisher deserves investigation, but the status alone does not prove that an app is malicious; a verified publisher can still request more access than your use case needs. Microsoft publisher verification.
Check the app's owner, intended use and permissions together. For an internal application, establish who maintains it and why it needs access. For a third-party service, also review how the provider handles the information it processes.
Turn the findings into an access decision
- Identify the connection and its owner. Confirm who uses the app and what work it supports.
- Compare permissions with the task. Decide whether the app needs broad document access or whether selected files would be sufficient.
- Prioritize sensitive resources and powerful actions. Review unnecessary access to customer data, confidential documents and credentials first.
- Remove or narrow access that lacks a business need. Coordinate with the owner so legitimate workflows are understood before permissions change.
- Recheck the result. Confirm that the unwanted grant is removed or restricted, and repeat the review as tools and permissions change.
Revoking access addresses the connection going forward. Do not assume it deletes information a provider has already received; data deletion is a separate question to resolve with that service.
Give AI an appropriate access boundary
AI can be useful for drafting, research and routine work. Those benefits do not require treating every integration as broadly trusted.
Manage an AI connection with the same care you would apply to another identity: give it a defined purpose, an accountable owner and only the data access and actions its work requires. Blue Lantern Security's AI access posture checks help you see the permissions that deserve review so you can make those decisions deliberately.
