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 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.
Automated recurring scans and email reporting
Cerber Security Scanner allows you to easily configure your schedule for automated recurring scanning. Once the schedule is configured the scanner will automatically perform the scan of the website and send a email report with results of the scan.
Read more about automated scans.
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.

-
Yes, easily. How to hide wp-admin and wp-login.php from possible attacks
- Can I rename the wp-admin folder?
-
Nope. It’s not possible and not recommended for compatibility reasons.
- Can I hide the fact I use WordPress?
-
No. We strongly encourage you not to use any plugin that renames wp-admin folder to protect a website.
Beware of all plugins that hide WordPress folders or other parts of a website and claim this as a security feature.
They are not capable to protect your website. Don’t be silly, hiding some stuff doesn’t make your site more secure. - Can WP Cerber Security work together with the Limit Login Attempts plugin?
-
Nope. WP Cerber is a drop in replacement for that outdated plugin.
- Can WP Cerber Security protect my site from DDoS attacks?
-
Nope. The plugin protects your site from Brute force attacks or distributed Brute force attacks. By default WordPress allows unlimited login attempts either through the login form or by sending special cookies. This allows passwords to be cracked with relative ease via a brute force attack. To prevent from such a bad situation use WP Cerber.
- Is there any WordPress plugin to protect my site from DDoS attacks?
-
Nope. This hard task cannot be done by using a plugin. That may be done by using special hardware from your hosting provider.
- What is the goal of Citadel mode?
-
Citadel mode is intended to block massive bot (botnet) attacks and also a slow brute force attack. The last type of attack has a large range of intruder IPs with a small number of attempts to login per each.
- How to turn off Citadel mode completely?
-
Set Threshold fields to 0 or leave them empty.
- What is the goal of using Fail2Ban?
-
With Fail2Ban you can protect site on the OS level with iptables firewall. See details here: https://wpcerber.com/how-to-protect-wordpress-with-fail2ban/
- Do I need to use Fail2Ban to get the plugin working?
-
No, you don’t. It is optional.
- Is WP Cerber Security compatible with other security plugins like WordFence, iThemes Security, Sucuri, NinjaFirewall, All In One WP Security & Firewall, BulletProof Security?

-
Yes! WP Cerber Security is not on the list of disallowed plugins.
- Is the plugin compatible with Cloudflare?
-
Yes, read more: https://wpcerber.com/cloudflare-and-wordpress-cerber/
- Does the plugin works on websites with SSL(HTTPS)
-
Absolutely!
- It seems that old activity records are not removing from the activity log
-
That means that scheduled tasks are not executed on your site. In other words, WordPress cron is not working the right way.
Try to add the following line to your wp-config.php file:define( ‚ALTERNATE_WP_CRON‘, true );
- I’m unable to log in / I’m locked out of my site / How to get access (log in) to the dashboard?
-
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 wp-cerber folder from the archive.
- Upload the wp-cerber folder to the plugins folder of your site using any FTP client or a file manager from your hosting control panel. If you see a question about overwriting files, click Yes.
- Log in to your site as usually. 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.
Rezensionen
The best protection plugin i found so far
The best protection plugin i found so far
Few problems here and there but excellent plugin overall
I’ve been using this plugin for as long as I can remember and I’ve had almost no complaints with it. It does everything I need. I love how I’m able to track every single failed login attempt and/or successful login.
The only negative thing I’ve found is that it can unnecessarily break parts of my contact form. More specifically, I noticed that if I try to submit something in the contact form, nothing happens (no message, no change of screen, nothing). I’m assuming it’s somehow blocking or rejecting this request? Either way, when I activated the „allow AJAX“ option under Antispam, it seemed to fix the problem.
Another problem I found is that it will unnecessarily lock me out after 1 failed attempt. I once entered the right username/email—but wrong password—and it immediately locked me out. As soon as the lockout was lifted, I put my IP on the whitelist so I wouldn’t make a mistake like this again, but I’m still a little confused by this bug?
Overall, it’s an excellent plugin. I use it for all my client websites and my own website as well. I would highly recommend it to others.
Effective, highly recommended
Amazing plugin. Thank you for your work!
Very effective!
Yes, its a very appreciated plugin!
The user interface is very transparent, i.e. easy to use
