Frequently Asked Questions

NinjaFirewall stands between the attacker and WordPress. It can filter requests before they reach your blog and any of its plugins. This is how it works:

Attacker > HTTP server > PHP > NinjaFirewall > WordPress

And this is how regular WordPress security plugins work:

Attacker > HTTP server > PHP > WordPress > Security Plugin

NinjaFirewall includes a very powerful filtering engine that can detect Web Application Firewall evasion techniques and obfuscation tactics used by hackers, as well as support and decode a large set of encodings. See our blog for a detailed description: An introduction to NinjaFirewall v3.0 filtering engine.

If you are using WordPress, you should install the WP+ Edition because it was specifically written to secure WordPress. The Pro+ Edition should be used with non-WordPress applications such as Joomla, Magento or any other PHP website.

You can use your license for your domain and its subdomains as well. For instance, if you created a license for example.com, you could use it for example.com, blog.example.com, www.example.com etc.

If you are planning to use NinjaFirewall (WP+ Edition) on a WordPress multisite installation, you will need one license only. Contact us if you are unsure.

  1. Create an account.
  2. Log in.
  3. Select a subscription plan and add credit* to your account using Paypal or a Credit Card.
  4. Create your license.
* After receiving your payment, we will credit your account accordingly and you will be free to use your account balance to create your NinjaFirewall license(s) whenever you want. For instance, if you only have one website but want to get a 20% off discount, select Plan #2 (2 to 5 domains), make your payment for two license and create your first license. Next year, when your license will expire, you could use your credit left to renew that license.

  1. Log in.
  2. Add funds to your account (or use your credit left if you have sufficient funds in your account) to pay the annual license fee.
  3. Renew the current license.
  4. Log in to WordPress, click on "NinjaFirewall > Dashboard > License" and enter the newly created license.

NinjaFirewall works on Unix-like servers only. There is no Microsoft Windows version and we do not expect to release any.

Will NinjaFirewall detect the correct IP of my visitors if I am behind a CDN service like Cloudflare or Incapsula?

If you are using NinjaFirewall (WP+ Edition), you can modify the source IP from the "Access Control > Source IP" menu. If you are using the free NinjaFirewall (WP Edition), you can use an optional configuration file to tell the firewall which IP to use. Please follow these steps.

How can I restrict access to NinjaFirewall settings and menu?

See our blog post: Restricting access to NinjaFirewall (WP Edition) settings.

I moved my wp-config.php file to another directory. Will it work with NinjaFirewall?

Just like WordPress does, NinjaFirewall will look for the wp-config.php script in the current folder or, if it cannot find it, in the parent folder.

Can I add/write my own security rules?

You can use the optional .htninja configuration file for that purpose.

Can I migrate my site(s) with NinjaFirewall installed?

In order to migrate your site, follow these steps:
  1. Export your NinjaFirewall configuration from the "Firewall Options" menu.
  2. With your FTP client, download its log and cache folders located in /wp-content/nfwlog/.
  3. Uninstall NinjaFirewall.
  4. Migrate your site.
  5. Upload its /wp-content/nfwlog/ folder to your new site (unless you already copied it during the blog migration).
  6. Install NinjaFirewall.
  7. Reimport its configuration from the "Firewall Options" menu.
Note: "File Check" configuration cannot be exported/imported, it will have to be reconfigured.

Lost password (brute-force protection)

If you cannot access your WordPress admin console because you lost the brute-force protection username and/or password:
  1. Connect to your server via FTP.
  2. Delete the /wp-content/nfwlog/cache/bf_conf.php script.
  3. Log in to the WP admin console, click on "NinjaFirewall > Login Protection" and reconfigure the brute-force protection options.

Cannot connect to WordPress database

After installing NinjaFirewall, the firewall returns the following error message:

NinjaFirewall fatal error : Cannot connect to WordPress database

Download our database test script:

  1. Rename this file to wp-db.php.
  2. Upload it into your WordPress root folder.
  3. Go to https://YOUR WEBSITE/wp-db.php
  4. Delete it afterwards.

Blocked visitors

Because each site is different, it is possible that the default configuration of NinjaFirewall may wrongly block some visitors. If it occurred, please consult this post: Testing NinjaFirewall without blocking your visitors
