HTTP and HTTPS
The Cisco Secure Client Umbrella Roaming Security module uses HTTP (80/TCP) and HTTPS (443/TCP) to communicate with Secure Access for the following uses:
- Initial registration upon installation
- Checking for new versions of the Cisco Secure Client Umbrella (Roaming Security) module
- Reporting the status of Cisco Secure Client Umbrella (Roaming Security) module to Secure Access
- Checking for new internal domains
Windows Only: If you utilize an HTTP proxy that is configured at the user-level (normally using GPO), make sure the SYSTEM user is also configured to use the proxy. Otherwise, add the following rules to your firewall to ensure the Cisco Secure Client Umbrella (Roaming Security) module can reach Secure Access.
