A: Great question! Both WP Security Ninja and Wordfence offer strong protection, but their approaches to real-time IP blocklists have some differences.

WP Security Ninja's firewall uses a multi-layered approach. It's built on the robust 8G firewall ruleset, and it also loads a massive, regularly updated blocklist of known malicious IPs, currently over 600 million. This list is collated from multiple sources, not just from sites running WP Security Ninja. In addition, all sites using the plugin contribute to a shared intelligence network, so if a new malicious IP is detected attacking one site, it can be quickly blocked across the entire network of sites using WP Security Ninja.

As for Wordfence, while I can't speak to their exact methods, they have a large and talented team and are well-known for their real-time threat intelligence. Their paid version also offers a real-time IP blocklist, and I'm sure they use a combination of their own data and other sources to keep their users protected.

WP Security Ninja does not rely on third-party services like Cloudflare for its core firewall or blocklist features.

Hope this helps clarify things! If you have any more questions, feel free to ask.
