Chrome log events

Depending on your Google Workspace edition, you might have access to the security investigation tool, which has more advanced features. For example, super admins can identify, triage, and take action on security and privacy issues. Learn more

As your organization's administrator, you can run searches and take action on security issues related to Chrome log events. For example, you can view a record of actions to track events related to managed Chrome browsers and ChromeOS devices. You can also see when there has been an unsafe site visit.

Before you begin

To see all Chrome events:

• The browser must be managed by Chrome Browser Cloud Management, a ChromeOS device that’s enrolled with your organization, or a user profile managed in Chrome browser.
• You must set up reporting for Chrome security events. For details, go to Manage Chrome Enterprise reporting connectors.
• To review Chrome data-protection events, you must set up Chrome Enterprise Premium . For details, go to Protect Chrome users with Chrome Enterprise Premium threat and data protection.

Forward log event data to Google Cloud

You can opt in to share log event data with Google Cloud. If you turn on sharing, data is forwarded to Cloud Logging where you can query and view your logs and control how you route and store your logs.

The type of log event data you can share with Google Cloud depends on your Google Workspace, Cloud Identity, or Essentials account.
