A very simple firewall for WordPress that allows you to see all real requests to your WordPress and protect you from Internet attacks. It’s a WAF, a Web Application Firewall that is installed in front of WordPress. It’s installed in the server with the plugin, and it checks requests from the web browsers, bots or webcrawlers to your WordPress. It executes the WAF codes before every request to PHP files of WordPress, so it also works before every request to the WordPress cache.
Features:
<ul>
<li>Feel free to contribute in GitHub to improve the project.</li>
<li>It’s free, completely free.</li>
<li>Detection and protection of DoS attacks.</li>
<li>Detection and notification of possible DDoS attacks.</li>
<li>It can protect you against SQL injection, XSS and Xploit attacks using your own Regexes.</li>
<li>Permanent block or bypass of custom IPs, it allows you to configure IPs with your own Regexes too.</li>
<li>Log and show Regex errors, for debug and improve your Regexes.</li>
<li>Save payloads, all or only when match a regex.</li>
<li>Block and allow countries and continents.</li>
<li>404s detections.</li>
<li>Show URLs or IPs doing 404s.</li>
<li>Show IPs that are doing most of the visits.</li>
<li>Show URLs most visited.</li>
</ul>
<h3>Uninstall</h3>
<ol>
<li>Uninstall .user.ini file.</li>
<li>Deactivate the plugin into the Plugins menu in the admin panel of WordPress.</li>
<li>Delete into the Plugins menu.</li>
</ol>
All the options configured into the plugin are removed when plugin is deleted, not when plugin is deactivated. All the database tables are removed when plugin is deactivated. So if you want to remove the plugin and all data stored, first deactivate the plugin and then remove it from the plugin admin zone into the WordPress backend.

<h3>How BitFire Compares</h3>
<h3>BitFire vs Wordfence</h3>
Wordfence is a solid product with a large team writing custom rules for known vulnerabilities. One important difference is how BitFire handles automated traffic:
<ol>
<li>Bot blocking – WordPress cannot reliably distinguish human traffic from automated traffic on its own. BitFire is designed to identify and block malicious bots before they can exploit or infect your site.</li>
</ol>
If you use Wordfence, we strongly recommend using the paid version.

<h3>Why Do Other Plugins Focus So Much on Cleaning Up Malware?</h3>
Good question. Have you noticed how much other security plugins charge for malware removal and how much of their marketing focuses on finding infections?
BitFire focuses on keeping malware off your site so you do not need to pay someone to remove it.
<h3>Privacy / Monitoring / Data Collection</h3>
We take your privacy seriously. Here is exactly what BitFire does with your data:
<ol>
<li>
Traffic inspection. BitFire inspects web traffic to your site to identify threats. Sensitive data, such as passwords and credit card numbers, is automatically replaced with redacted in logs. You can add additional fields to filter in the settings.
</li>
<li>
Error reporting. If BitFire encounters a software error, it can send a report to our development team so we can fix it in a future release. No visitor data is included in these reports.
</li>
<li>
Malware hash checking. BitFire sends small numeric fingerprints, known as 64-bit hashes, of your files to our hash server to compare them against our database of known-good files. For example, a file might hash to the number <code>812612388126487</code>. We never receive your actual file contents, and file hashes are not stored on our servers.
</li>
<li>
Local data storage. All log data and configuration files are stored locally on your server in a hidden, randomly named directory under <code>wp-content/uploads/</code>. This directory is protected by an <code>.htaccess</code> file and is not accessible from the web.
</li>
</ol>
