Limit login attempts done right
By default, WordPress allows unlimited login attempts through the login form, XML-RPC or by sending special cookies. This allows passwords to be cracked with relative ease via brute force attack.
WP Cerber blocks intruders by IP or subnet from making further attempts after a specified limit on retries is reached, making brute force attacks or distributed brute force attacks from botnets impossible.
You will be able to create a Black IP Access List or White IP Access List to block or allow logins from a particular IP address, IP address range or a subnet any class (A,B,C).
Moreover, you can create your Custom login page and forget about automatic attacks to the default wp-login.php, which takes your attention and consumes a lot of server resources. If an attacker tries to access wp-login.php they will be blocked and get a 404 Error response.
Malware scanner
Cerber Security Scanner is a sophisticated and extremely powerful tool that thoroughly scans every folder and inspects every file on a website for traces of malware, trojans, backdoors, changed and new files.
Read more about the malware scanner.
Integrity checker
The scanner checks if all WordPress folders and files match what exist in the official WordPress core repository, compares your plugins and themes with what are in the official WordPress repository and alerts you to any changes. As with scanning free plugins and themes, the scanner scans and verifies commercial plugins and themes that are installed manually.
Scheduled Scans With Automatic File Recovery
Cerber Security Scanner allows you to configure a schedule for automated recurring scanning easily. Once the schedule is configured the scanner automatically scans the website, deletes malware and recovers modified and infected WordPress files. After every scan, you can get an optional email report with the results of the scan.
Read more about the scheduled scans.
Two-Factor Authentication
Two-Factor Authentication (2FA) provides an additional layer of security requiring a second factor of identification beyond just a username and password. When 2FA is enabled on a website, it requires a user to provide an additional verification code when signing into the website. This verification code is generated automatically and sent to the user by email.
Read more about Two-Factor Authentication.
Log, filter out and export activities
WP Cerber tracks time, IP addresses and usernames for successful and failed login attempts, logins, logouts, password changes, blocked IP and actions taken by itself. You can export them to a CSV file.
Limit login attempts reinvented
You can hide WordPress dashboard (/wp-admin/) when a user isn’t logged in. If a user isn’t logged in and they attempt to access the dashboard by requesting /wp-admin/, WP Cerber will return a 404 Error.
Massive botnet brute force attack? That’s no longer a problem. Citadel mode will automatically be activated for awhile and prevent your site from making further attempts to log in with any username.
Cerber anti-spam engine
Anti-spam and anti-bot protection for contact, registration, comments and other forms. WP Cerber anti-spam and bot detection engine now protects all forms on a website. No reCAPTCHA is needed. It’s compatible with virtually any form you have. Tested with Gravity Forms, Caldera Forms, HappyForms, Contact Form 7, Ninja Forms, Formidable Forms, Fast Secure Contact Form, Contact Form by WPForms.
Anti-spam protection: invisible reCAPTCHA for WooCommerce
- WooCommerce login form

What does « Cerber » mean?
Cerber is derived from the name Cerberus. In Greek and Roman mythology, Cerberus is a multi-headed dog with a serpent’s tail, a mane of snakes, and a lion’s claws. Nobody can bypass this angry dog. Now you can order WP Cerber to guard the entrance to your site too.

Installation
Installing the WP Cerber Security plugin is the same as other WordPress plugins.
- Install the plugin through Plugins > Add New > Upload or unzip plugin package into wp-content/plugins/.
- Activate the WP Cerber through the Plugins > Installed Plugins menu in the WordPress admin dashboard.
- Read carefully: Getting Started Guide
Important notes
- Before enabling invisible reCAPTCHA, you must obtain separate keys for the invisible version. How to enable reCAPTCHA.
- If you want to test out plugin’s features, do this on another computer (or incognito browser window) and remove computer IP address or network from the White Access List. Cerber is smart enough to recognize « the boss ».
- If you’ve set up the Custom login URL and you use some caching plugin like W3 Total Cache or WP Super Cache, you have to add the new Custom login URL to the list of pages not to cache.
- Read this if your website is under CloudFlare
- If you use the Jetpack plugin or another plugin that needs to connect to wordpress.com, you need to unlock XML-RPC. To do that go to the Hardening tab, uncheck Disable XML-RPC, and click the Save changes button.
The following steps are optional but they allow you to reinforce the protection of your WordPress.
- Fine tune Limit login attempts settings making them more restrictive according to your needs
- Configure your Custom login URL and remember it (the plugin will send you an email with it).
- Once you have configured Custom login URL, check ‘Immediately block IP after any request to wp-login.php’ and ‘Block direct access to wp-login.php and return HTTP 404 Not Found Error’. Don’t use wp-admin to log in to your WordPress dashboard anymore.
- If your WordPress has a few experienced users, check ‘Immediately block IP when attempting to log in with a non-existent username’.
- Specify the list of prohibited usernames (logins) that legit users will never use. They will not be permitted to log in or register.
- Configure mobile and browser notifications via Pushbullet.
- Obtain keys and enable invisible reCAPTCHA for password reset and registration forms (WooCommerce supported too).

There is a special version of the plugin called WP Cerber Reset. This version performs only one task. It resets all WP Cerber settings to their initial values (excluding Access Lists) and then deactivates itself.
To get access to your dashboard you need to copy the WP Cerber Reset folder to the plugins folder. Follow these simple steps.
- Download the wp-cerber-reset.zip archive to your computer using this link: https://wpcerber.com/downloads/wp-cerber-reset.zip
- Unpack the wp-cerber folder from the archive.
- Upload the wp-cerber folder to the plugins folder of your WordPress using any FTP client or a file manager in your hosting control panel. If you see a question about overwriting files, click Yes.
- Log in to your website as usual. Now WP Cerber is disabled completely.
- Reinstall the WP Cerber plugin again. You need to do that, because WP Cerber Reset cannot work as a normal plugin.

The plugin helps us to generate security. sometimes it is very sensitive.
I find it a serious problem that the support sometimes takes 14 days or longer to respond even though you have purchased a premium license.

We have used WP Cerber on a few websites and it has always done the job intended - keeping the hackers out and allowing the legitimate users in. We did penetration testing and it passed with 100% success, especially after applying some of the hardening options. And it has withstood a few attacks. Thanks WP Cerber!
