BitFire Security – RASP Firewall & Malware Cleaner



Protect yourself from 0-day threats with security processes, not just signatures.

Infected with malware?
BitFire malware scanner has one of the highest malware detection rates in the industry.
Most malware scans take less than 60 seconds. See the data:
**WordPress Malware Detection Rates vs WordFence

Complete Bot protection
Automated scanning tools make up 99.99% of all WordPress hacks.
BitFire is the only WordPress security plugin that tracks every bot on your website.
We compare each bot visit against a list of 600 known good bots and only allow them if their IP address is valid.
This prevents hackers from impersonating good bots like GoogleBot and bypassing your security.
See every bot accessing your site and approve or deny it.

Integrated human verification
BitFire integrates a free human verification system that validates your visitors are real humans.
Using integrated JavaScript, humans can only access your website after answering a JavaScript challenge.
This works similar to cloudflair human verification but is much faster, usually < 100 milliseconds.

Human verification is important to block hackers since many automated hacking tools impersonate
web browsers. BitFire stops all of these from accessing your website.

Runtime Application Self Protection
BitFire is the only RASP firewall for WordPress.
*How RASP works from checkpoint
Integrated directly with WordPress and your webserver, bitfire stops malware before it can infect your site.

RASP File Protection
File-Protection runs anytime a PHP file is attempted to be modified on your server.
BitFire intercepts the write and verifies that a valid site administrator is modifying the file and not a hacker.
This prevents any malware from infecting your site even if the firewall missed it.

RASP Database Protection
Database-Protection monitors SQL queriers to your WordPress database.
Anytime data is attempted to be modified BitFire inspects the tables being updated.
If the query is attempting to create a new user or update permissions to administrator level,
BitFire will block the query unless the user is logged in as an administrator.

This defeats any attempt by hackers to install backdoor accounts onto your server.

RASP Network Protection
Last, BitFire RASP intercepts all network requests from your webserver to the Internet.
BitFire blocks all Server Side Request Forgery attempts, stops all Time Of Use, Time of Check attacks (TOUTOC) and prevents your server from talking to a malware command and control servers.

Privacy / Monitoring / Data Collection

  1. Privacy. We take privacy very seriously. BitFire inspects all traffic going to the webserver and takes care to filter out any potentially sensitive information by replacing it with redacted. The config.ini file includes a list of common sensitive field names under the “filtered_logging” section. You can add additional fields to filter in the config file by adding a line “filtered_logging[field_name] = true” and replacing “field_name” with the name of the desired parameter to filter.

  2. BitFire includes an error handler which monitors it’s operation. In the event an error is detected only in the BitFire software; including during install, an alert can be sent to BitFire’s developer team. The development team monitors these errors in real time and includes fixes for any detected errors in each new release.

  3. Updates. Four times a day BitFire will request the latest signatures from the BitFire signature API. These signatures are sent over SSL(TLS) and encrypted specifically for each client site. In addition bitFire also sends a list of installed plugins and version numbers to compare against recently posted security vulnerabilities.


  • BitFire shows detailed graphs about the type of attacks your website is defending.
  • Bot Control page allows instant authentication of over 600 known bots.
  • Detailed malware scanner contains over 20 million data-points and scans 10,000 PHP files per minute.
  • View detailed block and alerting information about each request, add blocking exceptions with a single click.
  • Database malware scanner with backup and restore points can identify malware comments and posts from over 2.5 million domains.
  • Plugin monitoring alerts you within the hour when new plugin vulnerabilities effecting your site are released so you can stay on top of important security updates.
  • Simple on/off configuration with granular rules can be set to alert to test new rules before actually blocking.


  • Install this plugin via WordPress plugin installer.
  • In your Plugin Dashboard, click “Activate Plugin.”
  • Open the BitFire Settings from your WordPress admin dashboard. Complete the setup wizard.
  • Run a malware scan from the BitFire malware menu and verify your site files are 100% clean.
  • Run a database malware scan to ensure your content does not have any links to over 2.5 million malware sites.
  • Monitor your firewall blocking on the BitFire Dashboard page


If other security plugins live up to their hype, why do they scan my site for malware daily?

That’s an excellent question. The majority of popular security plugins create custom signatures for each WordPress plugin vulnerability as they are publicly disclosed. With over 10,000 known WordPress security vulnerabilities and less than 200 signatures, they miss blocking a lot of hacks. They are also unable to block the most common security flaws (access control errors) for anything they do not have a pre-built signature for. To make the situation more difficult, they delay these rules by up to a month for non-paying customers.

Can BitFire block bots and automated attacks?

BitFire’s primary feature is bot blocking which is 100% functional in the free version. 99% of WordPress attacks are from automated tools scanning every domain and IP address for known vulnerabilities. BitFire verifies human web browsers with a JavaScript challenge similar to Cloudflare but over 50 times faster (1/10 second VS 6 seconds). BitFire also includes a list of over 80 search engines and SEO tools that are network verified to ensure only valid bot traffic reaches your site.

Do I have to buy it?

BitFire includes a complete standard firewall, malware scanning, vulnerability detection offsite database backup and unbreakable bot blocking for free. Our patented RASP technology and SMS based 2FA is only available to our paying PRO and PREMIUM clients.

How does Redirection Protection work?

Our unique software keeps track of every 3rd party domain your web page uses (Facebook, Google, JavaScript APIS, themes, etc.). After several weeks of learning, CSP security headers are sent to visitors instructing their browsers to only use or redirect to your approved domain list.

Does BitFire prevent Cross-Site Scripting (XSS)?

BitFire includes outstanding XSS protection, including HTTP headers and content filtering for persistent, reflected, and DOM-based XSS attacks.

Does BitFire block SQL Injection attacks (SQLi)?

Yes. BitFire has advanced SQL parsing similar to MySQL syntax parsing and can understand SQL queries regardless of encoding, injected comments, and other evasion techniques.

Why shouldn’t I use WordFence?

If you use WordFence, you should only use the paid version. WordFence has a team monitoring emerging WordPress vulnerabilities and writing custom rules to block specific exploits. They are very good at it and run a great blog on their work. Paying customers receive these virtual patches as soon as they are available. Free customers receive the patches 30 days later. If your website is vulnerable, it is almost guaranteed to be hacked before the patch is available to free customers. Don’t leave your site at risk.

Why is BitFire better than WordFence?

“Better” can be subjective. Our generic attack detection is on-par, if not better. WordFence does not have browser or bot network authentication and can not block many automated attacks. BitFire is the only WordPress plugin offing operating system integrated file-locking and browser enforced redirect protection.
We are also definitely FASTER. WordFence typically doubles page load time, adding 100-200ms to every request on typical dedicated T4 small/medium AWS servers, more for shared environments. BitFire runs under 5ms on similar AWS hardware and near 10ms on shared environments.

We believe BitFire is the only plugin that can effectively protect WordPress sites – and is the only one with a 100% money-back guarantee for paid customers (up to 12 months effective).

I don't know much about security but the creator of this plugin Cory does. He personally gave me tips and he configured my settings and actually taught me about hacks and bots and stuff and he showed me how Bitfire protects me from hacks.

I woke up yesterday to a hacked website which kept redirecting me to a spam site. I couldn't log in or anything. I found a youtube video about BitFire and contacted them. They got right back to me, installed the software directly on my server, found the malware, cleaned it and then spent almost an hour on the phone talking me through my web site security and even gave me some pointers about my page load time. crazy! super nice guy. Highly recommend contacting them and using their malware scanner.
