# Threat Blocker

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

You may set up Threat Blocker in [Control Panel > Settings > Threat Blocker & DNS](https://app.goodaccess.com/threat-blocker-and-dns/).

## 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](/configuration-guides/features/custom-domain-blocking.md), [Custom Domain Names](/configuration-guides/features/dns-management.md#custom-domain-names-for-your-systems) and [GoodAccess DNS servers](/configuration-guides/features/dns-management.md#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**.
