What does the free SiteLock WordPress plugin do?

The plugin gives you a fast way to enable baseline hardening and login protections directly in WordPress. When connected to a free SiteLock account, you can also run on-demand cloud security posture checks that won’t slow down your server. It’s a great first step for site owners who want clarity and quick wins.

Can SiteLock improve my WordPress website's performance?

Using WordPress security plugins sometimes comes at a cost: requests, logs, analytics, and even blocking all happen directly on your web server. However, SiteLock protects at the perimeter. The plugin is designed to be lightweight, with heavier checks handled through our cloud-based architecture. 

When connected to an eligible plan that includes our CDN, SiteLock can also help improve website speed and performance while providing industry-leading security.

My hosting company already includes security — why do I need SiteLock?

Your hosting provider secures the server infrastructure their platform runs on. SiteLock protects what's on it: your WordPress files, code, plugins, and databases. These are separate layers, and most hosting security doesn't extend to your actual website. SiteLock works at the application level — where 96% of WordPress breaches happen.

How does Cloud-based security solve the problem?

Using cloud-based technology, we are able to scan and protect your WordPress site outside your normal hosting operations, which improves performance. Plus, by filtering, controlling, and monitoring the traffic, SiteLock is able to provide real-time protection, virtual patching, and DDoS attack prevention.

Will my site be protected from vulnerabilities?

A vulnerability is a weakness in code that can provide a “backdoor” into site applications so cybercriminals can gain unauthorized access to your site. SiteLock provides WordPress vulnerability scanning to easily detect these weaknesses. Once they are identified, our vulnerability patching can automatically fix weaknesses within WordPress quickly, so your site remains secure.

Does SiteLock update WordPress Themes and Plugins for me?

No, SiteLock does not update WordPress themes and plugins. Our solution patches the security vulnerabilities found in your site, which is different from updating themes and plugins. Our technology safely and surgically applies individual security patches, assuring that the installation is as secure as the latest version of the CMS without extra manual effort from site owners.
