Six of the Best WordPress Security Plugins for Protecting Your Website in 2023

Here are some of the best WordPress security plugins that I found, with a brief summary of their features:

Best 6 WordPress Security Plugin:
1. Sucuri
2. Jetpack
3. Wordfence
4. iThemes Security(Solid Security)
5. WPScan
6. WP-Firewall

The first one is Sucuri:

This plugin is a cloud-based security platform that offers a website application firewall, monitors and scans your website for threats, checks SSL certificates, scans for SEO spam, offers zero-day exploitation protection, repairs and restores hacked websites, and offers a content delivery network (CDN) to speed up performance among other features​.

One of the standout features of Sucuri is its Web Application Firewall (WAF). This firewall acts as a protective shield between your website and the rest of the internet. It scans and filters out malicious traffic before it can even reach your server. This preemptive approach to security helps to prevent damage and maintain the integrity of your website​.

In addition to its WAF, Sucuri provides several other security measures designed to keep your website safe and secure:

1. Threat Monitoring and Scanning: Sucuri continuously monitors your website for potential threats. It uses advanced scanning techniques to detect any signs of malicious activity. This includes checking your SSL certificates and scanning for SEO spam, which can negatively affect your search engine rankings​.
2. Zero-Day Exploitation Protection: Sucuri provides protection against zero-day exploits, which are attacks that take advantage of software vulnerabilities that are unknown to the software vendor. Sucuri's security team keeps a watchful eye on emerging threats and regularly updates the plugin's defenses to protect your website against the latest exploits​.
3. Website Repair and Restoration: If your website has been compromised, Sucuri can help repair and restore it. This can be a lifesaver, allowing you to quickly recover from a security breach and minimize downtime​.
4. 內容傳遞網路 (CDN): Sucuri offers a CDN to improve the performance of your website. A CDN can speed up your site by storing copies of your website's content on servers located around the world, allowing visitors to access your site from a server that is geographically close to them. This not only improves user experience but can also reduce the load on your original server, enhancing security​.
5. HTTP/2 Support: HTTP/2 is the latest version of the HTTP protocol, and it offers several improvements over its predecessor, including faster page load times and better SEO. Sucuri supports HTTP/2, which can further boost your website's performance and enhance user experience​.
6. WordPress Security Hardening: Sucuri offers options for WordPress security hardening, which are a set of practices and configurations designed to improve the security of your WordPress website.
7. Minimizing Active Plugins: One of the most common ways that hackers can exploit WordPress websites is through vulnerabilities in plugins. Sucuri's security hardening measures recommend minimizing the number of active plugins on your site. This reduces the number of potential entry points for hackers, helping to keep your site secure.
8. 使用強密碼: Strong, unique passwords are a fundamental part of good website security. Sucuri encourages the use of complex passwords that are difficult for others to guess or crack. By implementing a strong password policy for all user accounts, you can significantly reduce the risk of unauthorized access to your website.
9. 限制登入嘗試: Sucuri's security hardening feature also provides the option to limit login attempts. This can be an effective defense against brute force attacks, where hackers attempt to gain access to your site by repeatedly trying different combinations of usernames and passwords. By limiting the number of failed login attempts from a single IP address, Sucuri can help to thwart these types of attacks.
10. File and Directory Permissions: Sucuri can help you set appropriate file and directory permissions on your WordPress installation. Correct permissions ensure that only authorized users can access and modify your site's files and directories, reducing the risk of unauthorized changes or data theft.
11. Database Security: Sucuri also provides options for hardening your WordPress database. This includes changing the default WordPress database table prefix, which can make it harder for attackers to execute SQL injection attacks. Additionally, Sucuri can help ensure that your database user has only the necessary permissions, reducing the potential damage if an attacker were to gain access to your database account.
12. Update Management: Sucuri emphasizes the importance of keeping your WordPress core, themes, and plugins up-to-date. Outdated versions of these components can contain security vulnerabilities, and Sucuri can help manage updates to ensure that you're always running the latest, most secure versions.
13. Advanced Security Measures: Sucuri also offers more advanced security hardening options, such as implementing a Web Application Firewall (WAF), enabling HTTPS, and more. These measures provide additional layers of protection for your website, making it even more difficult for attackers to compromise your site.
