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.

Release history
- A setting link in admin UI now opens the matching role tab in the role-based settings and highlights the target setting, so you can jump from an Activity log event straight to the setting that affected WP Cerber's decision.
- Following a setting link from a popup explainer now centers the target WP Cerber setting in the browser window instead of aligning it with the top of the page, where the WordPress admin bar could cover it.
- URL escaping in the admin interface now accepts root-relative URLs that begin with a single slash, in addition to the already supported HTTP(S), FTP(S), and mailto URLs.
- Admin announcements are now stored as structured JSON instead of pre-rendered HTML markup. A stored announcement that does not match the supported format is rejected instead of being displayed incorrectly.
- Quotes, angle brackets, and backticks are no longer deleted from URLs in admin pages. HTML escaping of the attribute value now handles these characters safely.
- On the Activity log page, when several explainers described events for the same user and WP Cerber's decision was role-based, only the first setting link scrolled to and highlighted the target setting. The remaining links opened the settings page without scrolling to the target setting.
- The "Mail Transport" settings section displayed the raw HTML markup for the "Available in the professional version of WP Cerber" link instead of a working link.
- Non-ASCII characters in a URL path are no longer removed when WP Cerber escapes a URL, so URLs with non-ASCII path characters now point to the intended address.
- A URL containing invalid UTF-8 no longer becomes an empty link address when WP Cerber escapes it.

- When error logging was active, an uncaught PHP failure such as an unhandled exception, a type error, or a parse error could stop the standard PHP fatal error processing. WordPress can again show its critical error page, send the Recovery Mode email, and revert a broken PHP edit made in the built-in plugin or theme editor.
- Uncaught PHP exceptions and other fatal failures could be missing from the WordPress `debug.log` file when `WP_DEBUG_LOG` was enabled.
- Not all PHP errors were logged for a request. A fatal error that terminated the request could be replaced by a later diagnostic produced by WP Cerber's own shutdown routines, so the terminating error was missing from the request details in Traffic Inspector and from `cerber-errors.log`.
- On a non-English website, the issue message reporting a failed email delivery could be shown in the language of the request that failed to send the email, which is usually an unattended request such as a scheduled report or a visitor-triggered alert. The message is now translated into the language of the administrator who reads it.
- On a non-English website, the message reporting corrupted plugin settings and their recovery was shown untranslated. It is now translated at the moment it is displayed to the administrator.
- Some messages in the "System Readiness" widget were missing localization support and could not be translated.
- Rendering the quick navigation block in the admin area could produce `Array to string conversion` warnings when a query parameter carried more than one value. Depending on the PHP error configuration, these warnings could pollute the server logs, appear in the admin output, or corrupt an AJAX response.
- Some valid IPv6 ranges written in dash or wildcard notation were rejected when adding an entry to the IP Access Lists or filtering records in the Activity log and the Traffic log. Reversed and zero-length ranges are still rejected.
- IPv6 range matching now uses inclusive boundaries, so the first and the last address of a range are treated as part of that range.
View changelog
- WP Cerber now automatically maintains a backup copy of the last known valid plugin settings. The backup is refreshed after successful settings updates, settings imports, plugin upgrades, and during daily maintenance.
- If the stored plugin settings become corrupted, WP Cerber now restores them automatically from the settings backup and shows a dismissible admin notice explaining what happened, what action was taken, and what the administrator should review.
- The "System Readiness" widget now shows an advisory notice on servers where PHP is built without the modern `mysqlnd` database driver. The notice confirms that WP Cerber keeps working and recommends enabling `mysqlnd` for full compatibility and better performance.
- Traffic Inspector now detects additional high-confidence JavaScript obfuscation patterns, including fully escaped strings that use `\uNNNN` and `\u{...}` escape sequences and dangerous execution, DOM, network, and system code decoded from explicit `fromCharCode()` calls, while preserving its low false-positive detection model.
- Compatibility: WP Cerber now runs correctly on legacy hosting environments where PHP is built without the modern `mysqlnd` database driver. On such servers, database query results are retrieved through a slower compatible method instead of triggering a fatal error.
- A corrupted WP Cerber configuration value stored in the database could cause a fatal `TypeError` in `array_merge()` at plugin load time on PHP 8, taking the whole website down. WP Cerber now detects the unreadable stored value, falls back to the default settings, and reports the failure as a critical issue until the administrator re-saves the settings.
- A regression in the detection of obfuscated JavaScript by Traffic Inspector. JavaScript strings built entirely of `\xNN` hex escape sequences were not decoded, so obfuscated code such as `eval`, `script`, and `XMLHttpRequest` could go undetected when request fields were inspected.
