5 Best Firewall Plugins for WordPress
WordPress is a platform that is very secure out of the box. However, due to its popularity, it is also a common target of many hackers. Of course, there are various strategies you can use to fortify your website from outside threats. You can strengthen your passwords, perform regular core, theme, and plugin updates to avoid any vulnerabilities, and even backup your website files in case a worst-case scenario happens. And while you can (and should) apply all these strategies, one of the best things you can do for your WordPress site is to add an extra layer of security by installing a solid firewall plugin.
Luckily, there are many great firewall plugins packed with features that can help you detect malicious attempts before any damage occurs. Without further ado, here is our pick of the plugins that will take the security of your WordPress site to a whole new level:
All In One WP Security & Firewall is a free, comprehensive, and easy-to-use firewall plugin solution for your WordPress site. It reduces the security threats by implementing the latest WordPress-recommended security practices as well as checking for any weaknesses in your website’s security as a whole.
Aside from login security, database, and file system features, there are many firewall features you get by installing the plugin as well. These include the ability to deny bad or malicious query strings and protect against Cross Site Scripting (XSS), access to WordPress PingBack Vulnerability Protection, the ability to log all 404 events on your site, and so on. You will also get to prevent others from hotlinking your images and will be able to block fake Googlebots from crawling your site. On top of all that, you will have access to the Cookie-Based Brute Force Login Prevention feature that will allow you to instantly block brute force login attacks. Some other features include the addition of a simple math captcha to the WordPress login form to fight against brute force login attacks, the ability to rename your admin login page URL (to prevent hackers and bots from accessing your real WordPress login URL), etc.
Finally, the plugin comes with awesome support and can be translated to over 10 languages.
With over 700,000 active installs on WordPress.org, Sucuri Security is another popular and all-encompassing plugin you can use to fortify your website for free.
