Browser extensions should not sit outside the software governance process.
Extensions can read or change page content, interact with sites, access browser functions, and update independently. The review process needs accurate inventory, permissions, ownership, policy, and change history.
01
Treat extensions as a distinct software class
Do not merge extensions into a generic application count. Their control model is different:
- They can be installed per browser profile.
- A managed account can be used on a managed or unmanaged browser.
- Permissions can change through updates.
- Publishers and store listings can change.
- Policy can force-install, allow, block, or limit extensions.
- Multiple browsers and profiles may exist on one endpoint.
02
Collect the fields needed for review
| Field | Purpose |
|---|---|
| Extension ID | Provides a stable identifier independent of display name |
| Name, version, and publisher | Supports identification and support review |
| Browser, profile, device, and user | Shows where the extension is active |
| Install source and policy state | Separates user-installed, force-installed, and externally installed records |
| Requested permissions | Supports risk and least-privilege review |
| First detected and last confirmed | Supports change and freshness analysis |
| Approval, owner, and business purpose | Connects technical presence to an accountable decision |
| Exception expiry | Prevents permanent undocumented allowance |
03
Enable reliable browser and profile reporting
Google documents extension reporting for enrolled Chrome browsers and ChromeOS devices. It also documents managed-profile reporting for organisation accounts. Reporting must be configured before the inventory can be treated as complete, and Google notes that data can take time to appear.
Record the management mode:
- Managed browser on a company device.
- Managed profile on a managed browser.
- Managed profile on an unmanaged browser.
- Unmanaged profile on a company device.
- Browser not enrolled or not reporting.
These states have different visibility and control implications.
04
Review risk and business purpose
What can it access?
Review site access, data access, browser functions, downloads, clipboard, and authentication interactions.
Who maintains it?
Confirm publisher identity, ownership changes, support history, and update behaviour.
Why is it required?
Record the business owner, workflow, affected users, and acceptable alternatives.
Where is it installed?
Consider privileged users, sensitive applications, broad host access, and fleet scale.
High permission counts are not automatically malicious. The decision depends on necessity, scope, publisher trust, data exposure, and compensating controls.
05
Apply policy deliberately
Google's enterprise guidance supports testing and evaluating extensions, blocking by permission, and using allow, block, and force-install policies. A practical policy model is:
- Block extensions by default for high-risk administrative groups where justified.
- Force-install only extensions that are required and centrally owned.
- Allow approved optional extensions through a documented process.
- Block known prohibited extensions and risky install sources.
- Limit host access and permissions where the platform supports it.
- Review forced and broadly permitted extensions on a schedule.
06
Track change and exceptions
Create review events when an extension appears, disappears, changes version, requests new permissions, changes publisher, or moves between policy states. Each exception should have a named owner, business purpose, affected group, approval, and expiry.
The audit should show both the current inventory and material changes during the review period.
07
Where Snipe RMM fits
Chrome extension inventory is a valid endpoint-evidence use case, but it should be presented as a planned capability until Snipe RMM collects and displays browser, profile, extension ID, version, permission, and policy evidence reliably. The product can still link browser evidence to the broader device, user, and activity record when that collection is implemented.
