Your WordPress site is a valuable asset and protecting it shouldn’t be complicated or expensive. The Sucuri WordPress Security Plugin offers a comprehensive suite of free tools designed to safeguard your site from malware, hacks, and vulnerabilities, all without slowing it down.
Sucuri helps you prevent security breaches before they happen. With features like remote malware scanning, blacklist monitoring, and security hardening, the plugin continuously monitors your site for vulnerabilities and threats giving you peace of mind and reducing the risk of downtime, data loss, or reputation damage.
If your site is compromised, Sucuri’s built-in post-hack recovery tools help you bounce back quickly. From resetting passwords and cleaning infected files to restoring core WordPress integrity, the plugin equips you with everything needed to regain control and secure your site without relying on external developers or costly emergency services.
Security hardening options are preventative measures to increase security in areas of your website that could become avenues for attack. This is done by adding a set of rules to the website .htaccess file and verifying secure configurations.
Email alerts are enabled by default. You can customize the email and recipients for any alerts generated by the plugin. These alerts will keep you informed of any suspicious activity observed on your website.
Our scanning engine is fast and lightweight for any environment. SiteCheck remote scanners are constantly updated to address the spread of malicious content, blocklisted status, website errors and out-of-date software.
The Sucuri WordPress plugin comes with tools that check the integrity of the core WordPress files – PHP, JavaScript, CSS – and other files that come with your original WordPress version.
This section of the plugin offers measures for when your site has been compromised. More information is available on steps to take when your site has been compromised in our free How to Clean a Hacked WordPress Guide.
You can connect the Sucuri Firewall to the WordPress plugin using the Firewall (WAF) option of the Sucuri plugin for advanced protection. This is only available for customers who have any of our platform plans and not as a feature included in the Sucuri plugin.
Keep in mind that the Sucuri Security plugin requires WordPress version 3.6 or higher, and administrative privileges for installation.
You have control over the Sucuri plugin settings to fit your website needs. Customize email alerts, schedule scans, allowlist or blocklist files, and more.
Our security plugin is user-friendly, but if you need additional help, you can always read our How to Use the WordPress Security Plugin Guide.
The Sucuri SiteCheck scan finds malicious code that is visible in the external source code of your site and identifies any core file integrity issues.
While the free Sucuri plugin offers powerful on-site protection, pairing it with the Sucuri Website Firewall (WAF) unlocks enterprise-grade defense against the most aggressive and sophisticated threats. The plugin integrates directly with the firewall, giving you unified control over your site’s security.
Sucuri’s Website Firewall (WAF) acts as a powerful shield between your WordPress site and malicious traffic. It filters harmful requests before they reach your server, protecting against DDoS attacks, zero-day exploits, SQL injections, cross-site scripting (XSS), and brute force attempts. This advanced layer of defense is especially valuable for high-traffic websites, online stores, and businesses handling sensitive data ensuring your site stays secure, fast, and accessible.
With the Sucuri Firewall enabled, you gain real-time visibility into potential threats and traffic anomalies. The plugin dashboard provides insights into blocked IPs, attack types, and geographic origins of malicious requests. You can also create custom rules to block specific countries, IP ranges, or user agents giving you precise control over who can access your site and how it's protected.
