Hardening

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.

Getting Started with the Plugin

1.

Install the WordPress Security Plugin

In a few simple steps, you can install the WordPress Security Plugin. Download the Sucuri Security plugin directly from the WordPress official repository to install it manually. Alternatively, from your WordPress Plugin dashboard, search for Sucuri and select Sucuri Security – Auditing, Malware Scanner and Security Hardening. Once the plugin is installed and activated, you can access all features by clicking the Sucuri Plugin option on the WordPress menu.
2.

Multisite and Subdomains

For the multisite installations, this is different. A WordPress MU installation will force each site to share the core files. Generally the content is inside the “wp-content” directory (where the plugin’s data is stored). All information processed by the plugin, except the settings, will be shared among every site inside the network. More details can be found in our WordPress Plugin Guide.

Seamless Integration with Sucuri Firewall (WAF)

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.

Advanced Threat Protection

Advanced Threat Protection

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.

Real-Time Monitoring & Blocking

Real-Time Monitoring & Blocking

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.
