# Firewall | RS Cloud

## What is the Firewall page?

The Firewall page in the /appliance web interface lets you manually configure or add networks to the block list for the B Series Appliance.

## How is it useful to my organization?

By managing the block list, administrators can prevent unauthorized connections, reduce security risks, and maintain a more predictable and secure operating environment. This ensures that only trusted network traffic interacts with the appliance, supporting stronger overall system protection.

## How do I access the Firewall page?

1. Use a Chromium-based browser to sign in to your B Series Appliance. The URL is provided in the BeyondTrust welcome email and includes your site URL followed by **/appliance**.
2. From the top menu, click **Security**.\
   The **Certificates** page opens and displays by default.
3. At the top of the page, click **Firewall**.\
   The **Firewall** page displays.
