Security Ninja Pro Cloud Firewall can use a shared list of known malicious IPs. When participating sites report blocked attack traffic, that intelligence helps other sites block those IPs earlier, before they hit your login form.
Free vs Pro
- Free: 8G-based request firewall that blocks many malicious request patterns.
- Pro Cloud Firewall: 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.
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 refreshes on a daily schedule in the background (secnin_update_cloud_firewall) from FireHOL Level 1, a public set of addresses tied to spam, malware, and attacks. That can stop some of those IPs before they hit comments, registration, or probes. It does not read email.
Privacy
Data sent for this feature is limited to what the block network needs, typically the blocked IP, the site reporting the block, and the reason. It is not used to build personally identifiable visitor profiles.
