# Firewall

Use IP Address Allowlisting to ensure only a specified set of IP addresses can communicate with your SingleStore Helios workspace.

You can add IP addresses to the firewall allowlist within the workspace:

1. Log in to the [Cloud Portal](https://portal.singlestore.com/), and select **Workspaces**.

2. Select the three dots for your workspace, and then select **Access & Security** from the list.

3. Scroll to the **Firewall** section. This section shows the IP addresses that have been allowlisted for inbound and outbound connections.

4. To add additional IP addresses, select **Edit**, and enter the address or range of addresses in the **Edit IP Address Access** dialog.

5. Select **Save**. The workspace will now allow access from the IP address(es) you added.
