## Threat Blocker

Threat Blocker provides automated detection and blocking of malicious domains. It draws on multiple threat intelligence feeds to protect against malware, ransomware, phishing, botnet C\&C, spammers, and more.

Threat Blocker is enabled by default.

{% hint style="danger" %}
**Please note:** Disabling Threat Blocker also disables [Custom Domain Blocking](https://support.goodaccess.com/configuration-guides/features/custom-domain-blocking), [Custom Domain Names](https://support.goodaccess.com/configuration-guides/dns-management#custom-domain-names-for-your-systems) and [GoodAccess DNS servers](https://support.goodaccess.com/configuration-guides/dns-management#dns-servers).
{% endhint %}

## Excluded domains

{% hint style="info" %}
This feature is available in the **Premium plan and higher**.
{% endhint %}

{% hint style="danger" %}
**Please note:** Excluding a domain will change the behavior of Threat Blocker and may increase security risk.
{% endhint %}

Threat Blocker will ignore domains listed here.

To exclude a specific domain, click the **+ Add domains** button.

You may specify the domain by its domain name or IP address.

Don't forget to **Save changes**.
