1. Objective

To provide step-by-step guidance for disabling the Symantec Endpoint Protection (SEP) browser extension in Google Chrome. This extension is typically installed alongside the SEP client to enforce web security policies, block malicious sites, and manage certificate validation. Based on your request, this feature falls under

Non-functional

• Changes propagate within a defined SLA (e.g., 10 minutes for cloud-managed, 1 hour for on-prem sync).
• Backwards-compatible with older SEP clients where possible; document unsupported versions.
• Secure authentication & RBAC for admin actions.
• Minimal performance impact on endpoints.

---

Security Considerations

• Force-disable must be auditable and require elevated privileges.
• Multi-admin approval for high-risk actions.
• Ensure tamper-resistance: local admins/users without enterprise privileges cannot re-enable when force-disabled.
• Log and monitor failed re-enablement attempts.

4. Troubleshooting Common Issues

• "This extension is managed and cannot be removed": This indicates the organization is using Group Policy to force the installation. You must remove the registry key (Method B2) or have IT remove the policy from the server side.
• Extension Reappears After Removal: If the SEP client service is running in the background, it may "repair" the installation and reinstall the extension. Stopping the Symantec service (smc.exe -stop) via command prompt (Admin) before removing the extension may prevent this temporarily.
• Performance Issues: Users often seek to disable this extension because it causes Chrome to run slowly or crash.
  • Alternative: Instead of disabling the extension, clearing the Chrome cache and ensuring SEP is updated to the latest version often resolves performance conflicts.

Admin UI

• Disable Extension page with:
  • Scope selector (groups, devices, OUs).
  • Mode selector: Soft-disable | Force-disable.
  • Duration or schedule fields (start, end).
  • Notification message (optional).
  • Require approval toggle (and approver list).
  • Review & confirm summary.
• Status dashboard:
  • Table: Scope | Mode | Status (Pending, In Progress, Applied, Failed) | Affected endpoints | Initiated by | Start/End | Actions (Re-enable, Edit, Cancel).
• Audit log viewer and export button.
