NinjaFirewall (WP Edition) – Advanced Security Plugin and Firewall vs Security Plugin, Firewall & Malware Scanner with Auto Removal

A true Web Application Firewall NinjaFirewall (WP Edition) is a true Web Application Firewall. Although it can be installed and configured just like a plugin, it is a stand-alone firewall that stands in front of WordPress. It allows any blog administrator to benefit from very advanced and powerful security features that usually aren’t available at the WordPress level, but only in security applications such as the Apache ModSecurity module or the PHP Suhosin extension. NinjaFirewall requires at least PHP 7.1, MySQLi extension and is only compatible with Unix-like OS (Linux, BSD). It is not compatible with Microsoft Windows. NinjaFirewall can hook, scan, sanitise or reject any HTTP/HTTPS request sent to a PHP script before it reaches WordPress or any of its plugins. All scripts located inside the blog installation directories and sub-directories will be protected, including those that aren’t part of the WordPress package. Even encoded PHP scripts, hackers shell scripts and backdoors will be filtered by NinjaFirewall. Powerful filtering engine NinjaFirewall includes the most powerful filtering engine available in a WordPress plugin. Its most important feature is its ability to normalize and transform data from incoming HTTP requests which allows it to detect Web Application Firewall evasion techniques and obfuscation tactics used by hackers, as well as to support and decode a large set of encodings. See our blog for a full description: An introduction to NinjaFirewall filtering engine. Fastest and most efficient brute-force attack protection for WordPress By processing incoming HTTP requests before your blog and any of its plugins, NinjaFirewall is the only plugin for WordPress able to protect it against very large brute-force attacks, including distributed attacks coming from several thousands of different IPs. See our benchmarks and stress-tests: Brute-force attack detection plugins comparison The protection applies to the wp-login.php script but can be extended to the xmlrpc.php one. The incident can also be written to the server AUTH log, which can be useful to the system administrator for monitoring purposes or banning IPs at the server level (e.g., Fail2ban). Real-time detection File Guard real-time detection is a totally unique feature provided by NinjaFirewall: it can detect, in real-time, any access to a PHP file that was recently modified or created, and alert you about this. If a hacker uploaded a shell script to your site (or injected a backdoor into an already existing file) and tried to directly access that file using his browser or a script, NinjaFirewall would hook the HTTP request and immediately detect that the file was recently modified or created. It would send you an alert with all details (script name, IP, request, date and time). File integrity monitoring File Check lets you perform file integrity monitoring by scanning your website hourly, twicedaily or daily. Any modification made to a file will be detected: file content, file permissions, file ownership, timestamp as well as file creation and deletion. Watch your website traffic in real time Live Log lets you watch your website traffic in real time. It displays connections in a format similar to the one used by the tail -f Unix command. Because it communicates directly with the firewall, i.e., without loading WordPress, Live Log is fast, lightweight and it will not affect your server load, even if you set its refresh rate to the lowest value. Event Notifications NinjaFirewall can alert you by email on specific events triggered within your blog. Some of those alerts are enabled by default and it is highly recommended to keep them enabled. It is not unusual for a hacker, after breaking into your WordPress admin console, to install or just to upload a backdoored plugin or theme in order to take full control of your website. NinjaFirewall can also attach a PHP backtrace to important notifications. Monitored events: Administrator login. Modification of any administrator account in the database. Plugins upload, installation, (de)activation, update, deletion. Themes upload, installation, activation, deletion. WordPress update. Pending security update in your plugins and themes. Stay protected against the latest WordPress security vulnerabilities To get the most efficient protection, NinjaFirewall can automatically update its security rules daily, twice daily or even hourly. Each time a new vulnerability is found in WordPress or one of its plugins/themes, a new set of security rules will be made available to protect your blog immediately. Strong Privacy Unlike a Cloud Web Application Firewall, or Cloud WAF, NinjaFirewall works and filters the traffic on your own server and infrastructure. That means that your sensitive data (contact form messages, customers credit card number, login credentials etc) remains on your server and is not routed through a third-party company’s servers, which could pose unnecessary risks (e.g., decryption of your HTTPS traffic in order to inspect it, employees accessing your data or logs in plain text, theft of private information, man-in-the-middle attack etc). Your website can run NinjaFirewall and be compliant with the General Data Protection Regulation (GDPR). See our blog for more details. IPv6 compatibility IPv6 compatibility is a mandatory feature for a security plugin: if it supports only IPv4, hackers can easily bypass the plugin by using an IPv6. NinjaFirewall natively supports IPv4 and IPv6 protocols, for both public and private addresses. Multi-site support NinjaFirewall is multi-site compatible. It will protect all sites from your network and its configuration interface will be accessible only to the Super Admin from the network main site. Possibility to prepend your own PHP code to the firewall You can prepend your own PHP code to the firewall with the help of an optional distributed configuration file. It will be processed before WordPress and all its plugins are loaded. This is a very powerful feature, and there is almost no limit to what you can do: add your own security rules, manipulate HTTP requests, variables etc. Low Footprint Firewall NinjaFirewall is very fast, optimised, compact, and requires very low system resource. See for yourself: download and install the Code Profiler plugin and compare NinjaFirewall’s performance with other security plugins. Non-Intrusive User Interface NinjaFirewall looks and feels like a built-in WordPress feature. It does not contain intrusive banners, warnings or flashy colors. It uses the WordPress simple and clean interface and is also smartphone-friendly. Contextual Help Each NinjaFirewall menu page has a contextual help screen with useful information about how to use and configure it. If you need help, click on the Help menu tab located in the upper right corner of each page in your admin panel. Need more security ?

Brute force, Login security & Two Factor Auth (2FA). Limit login. Malware & Vulnerabilities scan. FireWall. Enterprise ready security plugin. SECURITY PLUGIN BY CLEANTALK (SPBCT) We focus on eliminating the most common security threats for WordPress. At the same time, we strive to ensure that site performance remains unaffected. To achieve this, each release goes through automated and expert-driven testing pipelines. We also verify performance using Google PageSpeed Insights and GTMetrix. Typically, we release a new version twice a month to keep features up to date and protection strong. SECURITY FEATURES Limit Login Attempts and rate limits for logins. Two Factor Authentication (2FA) Custom wp-login URL (wp-login.php) Hide Login Default Login Page Disable or Stop User Enumeration Brute force protection for WordPress accounts and passwords Security Protection for WordPress login form Security FireWall by IP, Networks, or Countries Web Application Firewall (WAF) Real-time traffic monitor (Visitors per pages, IPs, Countires and hits counts per page) Malware scanner with auto-cure function Daily auto malware scan Vulnerabilities scanner among installed plugins and themes Security weekly reports to email Notifications of login events to your website FREE TRIAL THEN $9 PER YEAR CleanTalk is a Cloud security service that protects your website from online threats and provides you great security instruments to control your website security. We provide detailed security stats for all of our security features to have a full control of security. We believe the most honest approach is when every user pays a small fee for using the service, rather than relying on a freemium model where some users subsidize others. The fee is as low as price of a good cup of coffee! So, the security plugin does not have a PRO version-it is completely free and works in combination with our premium Cloud security service at cleantalk.org. Every user has full access to all features of both the service and the plugin. Also, please take a note about WordPress.org policy BRUTE FORCE PROTECTION Our default anti–brute-force policy works as follows, For any failed login attempt to the WordPress admin area, the plugin introduces a brief delay of a few seconds. The plugin reviews the security audit log every hour. If any IP address records 10 or more login attempts in that period, it will be blocked for 24 hours. ALL BRUTE FORCE PROTECTION FUNCTIONS Maximum failed attemtps to login before ban (default is 5). A failed attempt happens when either the login or password is incorrect. Time frame to count login attempts (default is 15 minutes). Ban to login time frame from 2 minutes to 24 hours (default is 1 hour). Two-factor authentication (2FA) with abillity to apply policy to specific users roles. Prevent collecting of login on password reset error. The option exclude the info about the login existing on password change error. Error message will be replaced with followed text: “If the user with the specified credentials exists, check your email for the password reset confirmation link. Then visit login page.” Security Audit Log. Keeps track of actions in the WP Dashboard to let you know what is happening on your blog. With the Security Audit Log is very easy to see user activity in order to understand what changes have done and who made them. Security Audit Log shows who logged in and when and how much time they spent on each page. Two Factor Authentication (2FA). It requires a bit of your time but Two Factor (2 Step) Authentication immediately gives a much higher level of security.With your first authorization, the CleanTalk Security plugin remembers your browser and you won’t have to input your authorization code every time anymore. However, if you started to use a new device or a new browser then you are required to input your security authorization code. CleanTalk security plugin will remember your browser for 30 days. Change the URL of the wp-login page. This option helps you change the default wp-login URL (wp-login.php). Hackers use scripts for massive brute-force attacks, and since most sites use a default login page URL, hackers configure scripts for such URLs. When you change the URL of the authorization page, hackers will not have the opportunity to perform brute-force attacks in scripts in automatic mode. This option does not change files and does not rewrite URLs in system files. To return the address of the default authorization page, it is enough to disable the option in the plugin settings or set a new value. If you are using caching plugins, then you need to add a new authorization page in the caching exceptions. Leaked password check. This feature enhances your website’s security by continuously monitoring users’ passwords for potential exposure in known data breaches and on the dark web. It works in the background and requires no action from users unless a leak is detected. SECURITY FIREWALL To enhance the security of your site, you can use the CleanTalk Security FireWall, which will allow you to block access by HTTP/HTTPS to your website for individual IP addresses, IP networks and block access to users from specific countries. Use personal BlackList to block IP addresses with a suspicious activity to enhance the WordPress security. Security FireWall may significantly reduce the risk of hacking and reduces the load on your web server. CleanTalk Security is fully compatible with the most popular VPN services. Also, CleanTalk security supports all search engines Google, Bing, Yahoo, Baidu, MSN, Yandex, and etc. LIST OF FIREWALL FUNCTIONS Blocks or bypass visitors by IP, IP Network. Country blocking. It also has option to avoid blocking hits from major search engines like Google, Bing, Yahoo, Baidu, Yandex, and etc. Traffic control. CleanTalk security Traffic Control will track every single visitor no matter if they are using JavaScript or not and provides many valuable traffic parameters. Another option in Security Traffic Control – “Block user after requests amounts more than” – blocks access to the site for any IP that has exceeded the number of HTTP requests per hour. If this number of requests will be exceeded, this IP will be added to the Security FireWall Black List for 24 hours. Security Firewall has a limit for requests to your website (by default 1000 requests per hour, so you can change it) and if any IP exceed this threshold it will be added to security firewall for next 24 hours. It allows you to break some of the DDoS attacks. Limit Login Attempts. Limit Login Attempts – is a part of brute-force protection and security firewall. Web Application FireWall (WAF) for WordPress Security Plugin. The main purpose of Web Application FireWall (WAF) is real-time protection from unauthorized access, even if there are critical known/unknown vulnerabilities. Security Web Application FireWall catches all requests to your website and checks HTTP parameters that include, SQL Injection, Cross Site Scripting (XSS), uploading files from non-authorised users, PHP constructions/code, the presence of malicious code in the downloaded files. In addition to effective information security and information security applications are required to know what is quality of protection and CleanTalk Security has logged all blocked requests that allow you to know and analyze accurate information. You can see your Cleantalk Security Logs in your Dashboard CleanTalk’s research team updates WAF database each time as we find a vulnerability, it means plugin’s users get protection even against unpublished vulnurebilites. Learn more how to set up and test About Security Web Application Firewall Email Notifications when administrators or users are logged in. We added this option to our security plugin. Now you can receive notifications if you want to know about an unauthorized entrance to your WP Dashboard. Notification will be sent only when a user was able to authorize entering login and password. If you are logged into the admin panel from the saved session, then the alert won’t be sent. MALWARE SCANNER WITH AUTO-CURE FUNCTION Scans WordPress files for hacker files or code for hacker code. Performs antivirus functions. Security Malware Scanner runs manually by users requests or automaticaly by WordPress cron. All of the results will send in your Security CleanTalk Dashboard with the details and you will be able to investigate them and see if that was a legitimate change or some bad code was injected. If you are unsure how to identify, remove, or clean malware using the plugin, you can book a malware removal service with our Security & Pentest team.
