How to Audit Chrome Extensions Across Company Devices

A browser extension is executable software with permissions, update channels, and supply-chain risk.

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

FieldPurpose
Extension IDProvides a stable identifier independent of display name
Name, version, and publisherSupports identification and support review
Browser, profile, device, and userShows where the extension is active
Install source and policy stateSeparates user-installed, force-installed, and externally installed records
Requested permissionsSupports risk and least-privilege review
First detected and last confirmedSupports change and freshness analysis
Approval, owner, and business purposeConnects technical presence to an accountable decision
Exception expiryPrevents 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

Permissions

What can it access?

Review site access, data access, browser functions, downloads, clipboard, and authentication interactions.

Publisher

Who maintains it?

Confirm publisher identity, ownership changes, support history, and update behaviour.

Purpose

Why is it required?

Record the business owner, workflow, affected users, and acceptable alternatives.

Exposure

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.

Do not treat one export as continuous control.

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.
