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.

As an alternative, you can use the Website Malware Scanner for frontend security and malware checks. It scans by URL and requires no plugins.

LIST OF MALWARE SCANNER, ANTIVIRUS FUNCTIONS

• Malware autoscanning. Scans the website automatically at intervals ranging from once every 12 hours to once every 30 days.
• Cure malware. It cures infected files automatically if the scanner knows cure methods for these specific cases. If the option is disabled then when the scanning process ends you will be presented with several actions you can do to the found files,
  • Cure. Malicious code will be removed from the file.
  • Replace. The file will be replaced with the original file.
  • Delete. The file will be put in quarantine. Do nothing.
    Before any action is chosen, backups of the files will be created and if the cure is unsuccessful it’s possible to restore each file.
• Security Malware Heuristic Check. This option allows you to check files of plugins and themes with heuristic analysis. Probably it will find more than you expect.
• Security Malware scanner to find SQL Injections. The CleanTalk Security Malware Scanner allows you to find code that allows performing SQL injection. It is this problem that the scanner solves.
• Operating system cron tasks analysis. This functional provides an overview of scheduled cron jobs on server that perform automated tasks.
• DB Trigger analysis. Will search for known malicious signatures in database triggers.
• List unknown files. Shows the list of found unknown files in the malware scanner report. Unknown files do not have known virus signatures and do not have suspicious code. Meanwhile, unknown files do not belong to the public plugins and themes at wordpress.org.
• File System Watcher. File system Watcher monitors changes in the file system. This allows to quickly respond to a site infection by tracking which files were affected. The Watcher makes file system snapshots as often as one hour and show difference up to seven days time frame.
• Feedback System. If you don’t have programming experience and don’t know, is there security issue or not, you send some files to CleanTalk Cloud and we check them for malware code. After checking we send you an email notification with results, is there viruses or not. Please, look at our guide How malware file analysis works About Scanner Feedback System
