Stop attackers before they reach WordPress

A WordPress firewall is a web application firewall for your site. It inspects incoming requests and blocks suspicious or known-bad traffic before it becomes a WordPress incident. Security Ninja Free includes basic 8G request filtering. Pro Cloud Firewall adds a living list of 600M+ known bad IPs, country rules, and IP controls.

Often yes. Edge and host WAFs stop a lot of volume before it reaches your server. A plugin firewall like Security Ninja still helps with WordPress-aware rules, login abuse, country and IP controls, and visibility inside wp-admin. Many sites use both, as long as rules do not fight each other.

Yes. Free includes a basic 8G firewall that filters common malicious request patterns. The Pro Cloud Firewall bad-IP database, country blocking, visitor log, and 404 Guard are Pro features.

Pro blocks visitors on a living cloud list of 600M+ known bad IPs, filters exploit-shaped requests, and can enforce country and custom IP rules. You can show a message to blocked visitors or redirect them. Login protection and 404 Guard sit alongside that stack on Pro.

It is built to allow legitimate traffic and known good crawlers where validation applies. You can whitelist IPs, use built-in service whitelists for many monitoring tools, and review blocks in the visitor log. After enabling country rules, test login, checkout, and important webhooks.

Stopping junk early usually reduces wasted PHP and database work. Cloud Firewall is meant to filter before WordPress does heavy lifting. Extreme overlapping firewall plugins can cause conflicts, so keep one clear application firewall stack.

Use Pro login protection to limit failed logins and optionally rename the login URL, then add 2FA for roles that matter. Cloud Firewall’s bad-IP list also reduces how often known attackers reach the form.

Yes on Pro. Country blocking uses IP2Location LITE data and lets you choose countries to block, including login-only options depending on your settings. Accuracy is good but not perfect, and VPNs can bypass country rules.

Before you enable Pro Cloud Firewall, save the secret access URL from the setup popup (you can email it to yourself). Whitelist your office or home IP when you can. Security Ninja includes recovery docs for the secret access URL and restoring access if you get locked out.

No. A firewall reduces attack noise. It does not patch vulnerable plugins or remove malware already on the site. Keep WordPress, plugins, and themes updated. Use the free vulnerability and core checks, and Pro malware scanning when you need file-level cleanup.

On Pro, use the visitor log for traffic and firewall decisions, and the Events Logger for security activity. You can also push alerts with webhooks to Slack, Discord, or Zapier.

It can, if payment gateways, CRMs, or other services call your site from a blocked country or IP. Whitelist required service IPs, prefer careful country rules, and test checkout after changes. Pro also includes WooCommerce rate and coupon protection alongside the firewall.
