Firewall

Firewall Protection helps protect your Mac from unwanted incoming network connections. Quick Heal Total Security lets you manage supported macOS firewall settings directly from the application.

Firewall Settings

You can configure the following settings to manage incoming network connections and application permissions.

Application Access

The application access list displays applications and their incoming connection permissions. Use the toggle next to an application to allow or block incoming connections for that application.

Review these permissions when you need to change whether an application can receive incoming network connections.

Allow or Block Incoming Connections for an Application

You can manage incoming connection permissions for individual applications. Allow incoming connections when an application needs to receive them, or block them when you do not want the application to receive incoming connections.

To change an application’s permission, follow these steps:

1. Open Quick Heal Total Security.
2. Navigate to Mac Security > Firewall Protection.
3. Under Choose which apps may receive incoming connections, locate the application.
4. Use the toggle next to the application to allow or block incoming connections.

To add an application to the list, select the + button and follow the on-screen instructions.

Block All Incoming Connections

Turn on Block all incoming connections to block incoming connections. Some system services may still be allowed to connect.

To configure this setting, follow these steps:

1. Open Quick Heal Total Security.
2. Navigate to Mac Security > Firewall Protection.
3. Turn the Block all incoming connections toggle on or off as required.

Automatically Allow Built-in Software to Receive Incoming Connections

Enable Automatically allow built-in software to receive incoming connections to allow built-in software to receive incoming connections automatically when required.

To configure this setting, follow these steps:

1. Open Quick Heal Total Security.
2. Navigate to Mac Security > Firewall Protection.
3. Turn the setting on or off as required.

Automatically Allow Downloaded Signed Software to Receive Incoming Connections

Enable Automatically allow downloaded signed software to receive incoming connections to allow downloaded signed software to receive incoming connections automatically.

To configure this setting, follow these steps:

1. Open Quick Heal Total Security.
2. Navigate to Mac Security > Firewall Protection.
3. Turn the setting on or off as required.

Stealth Mode

Enable Stealth Mode to configure the firewall to ignore network access attempts from unauthorized applications.

To configure Stealth Mode, follow these steps:

1. Open Quick Heal Total Security.
2. Navigate to Mac Security > Firewall Protection.
3. Turn Enable stealth mode on or off as required.

Managing Application Rules

Application rules determine whether individual applications are allowed to receive incoming network connections. You can review the application access list and use the corresponding toggle to change a permission.

When reviewing an application rule, check that the selected permission matches your requirements. If you need to add an application, use the + button and follow the on-screen instructions.

Changing an Application Rule

You can change an application’s incoming connection permission from the Firewall Protection screen.

1. Open Quick Heal Total Security.
2. Navigate to Mac Security > Firewall Protection.
3. Locate the application under Choose which apps may receive incoming connections.
4. Use the application’s toggle to change its incoming connection permission.

When Should You Review Firewall Settings?

Review your firewall settings when you want to:

• Check whether Firewall Protection is enabled.
• Change how incoming network connections are handled.
• Allow or block incoming connections for an individual application.
• Review how built-in software or downloaded signed software is allowed to receive incoming connections.
• Change the Stealth Mode setting.

Troubleshooting Application Connectivity

If an application cannot receive incoming connections as expected, review its permission in the application access list.

1. Open Quick Heal Total Security and navigate to Mac Security > Firewall Protection.
2. Locate the application under Choose which apps may receive incoming connections.
3. Check whether its toggle allows incoming connections.
4. Review the other firewall settings that may affect incoming connections.

If the issue continues, check the application’s requirements and the relevant macOS firewall settings. Avoid changing unrelated settings while troubleshooting.

Best Practices for Firewall Protection

• Keep Firewall Protection enabled unless you have a specific reason to disable it.
• Review application permissions when you need to change which applications can receive incoming connections.
• Check the effect of Block all incoming connections before enabling it, as some system services may still be allowed to connect.
• Review the available firewall settings when an application’s incoming connections do not behave as expected.

Important

• Quick Heal Total Security lets you manage supported macOS firewall settings from the application.
• The available settings control incoming connections and permissions for individual applications.
• Some system services may still be allowed to connect when Block all incoming connections is enabled.
• Available controls and their behaviour depend on the supported macOS firewall settings.
