7 Tools To Scan WordPress Sites for Vulnerabilities

What is the best tool to scan WordPress sites? We often hear this question from site owners and web agencies looking to protect their online presence. With plugins accounting for 91% of all WordPress vulnerabilities and themes responsible for another 9%, choosing the right security scanner is critical.

So, what’s the best tool to scan WordPress sites and catch these problems before hackers do? While we might be biased, WP Umbrella is one of the best tools for its real-time monitoring of security vulnerabilities and performance issues.

But don’t just take our word for it. In this post, we’ll compare seven powerful WordPress security tools to help you decide.

7 Tools for WordPress Security Check

1. WP Umbrella: WordPress Security Monitoring Tool; Now with Site Protect

WP Umbrella is a security monitoring platform that scans WordPress websites every six hours to detect plugins, themes, and WordPress core vulnerabilities. It operates differently from traditional security plugins by focusing on detection and alerting rather than active threat mitigation. Using Patchstack’s vulnerability database, WP Umbrella identifies security issues before they can be exploited.

WP Umbrella is for agencies and developers managing multiple WordPress sites from a single dashboard. Its security functionality is integrated with other monitoring tools (uptime, performance, PHP errors) to provide comprehensive website management. This integration allows teams to identify potential security issues across numerous websites without logging into each WordPress admin area individually.

The most significant upgrade to WP Umbrella’s security offering is Site Protect, a virtual patching add-on powered by Patchstack. This is where WP Umbrella moves beyond monitoring into active, proactive protection, and it addresses one of the biggest gaps in standard security workflows.

Most agencies do not update plugins the moment a patch comes out. There is often a testing backlog, client approval delays, or compatibility concerns. Meanwhile, attackers move quickly. As soon as a vulnerability is disclosed publicly, exploit attempts spike. Site Protect closes that window by applying targeted rules that block the exact exploit at the PHP level, before WordPress even fully loads, regardless of whether the plugin has been updated.

Unlike traditional security plugins that rely on scanning engines and malware detection after the fact, Site Protect is lightweight, runs silently at the PHP level, and has no measurable performance impact, even across hundreds of sites. Rules are updated continuously from Patchstack’s real-time threat database, so your sites stay protected without any manual intervention.

Enabling Site Protect takes about two clicks. go to the Security tab for any site in your WP Umbrella dashboard, toggle Site Protect on, and it handles the rest. You can also enable it in bulk across all sites from a single screen. Client reports automatically include a dedicated section showing how Site Protect has been proactively protecting their sites, which is useful if you are running a maintenance offering and need to demonstrate value.
