title: Block IP network (global bad IPs)

Security Ninja Pro’s Cloud Firewall can join a shared network of known malicious IPs. When participating sites report blocked hack attempts, that intelligence is used so other sites can block those IPs earlier, before they hit your login form.

## Free vs Pro

* **Free:** includes the [8G-based request firewall](https://wpsecurityninja.com/docs/firewall/8g-firewall-rules/) that blocks many malicious request patterns.
* **Pro Cloud Firewall:** adds the shared bad-IP list (**600M+** known bad IPs), plus login protection, country blocking, rename login, 2FA, and related controls. See [How to use the firewall](https://wpsecurityninja.com/docs/firewall/how-to-use-the-firewall/).

## Global bad IP network

When enabled, Pro sites can submit blocked IPs (and related block reasons) to the central service and receive updates to the shared list. The bad-IP list is refreshed on a **daily** schedule in the background.

## Privacy

Data sent for this feature is limited to what is needed for the block network, typically the blocked IP, the site reporting the block, and the reason. It is not used to collect personally identifiable visitor profiles.
