The 10 Best WordPress Vulnerability Scanners for Boosting Security

Ensuring your WordPress site is secure should be a top priority, but with so many potential vulnerabilities, keeping track of risks can feel overwhelming. This is where a dedicated WordPress vulnerability scanner comes in handy.

In this comprehensive guide, we’ll explain exactly what these scanners do, the value they provide, and the 10 best options in 2023 for finding and fixing security flaws in your WordPress site.

What is a WordPress Vulnerability Scanner?

A WordPress vulnerability scanner is a specialized security tool that scans your WordPress site for vulnerabilities, malware, misconfigurations, and other security risks.

It goes far beyond just checking if your core, plugins and themes are up-to-date. Quality scanners dig deep to identify issues like:

  • Outdated plugins, themes or PHP versions
  • Insecure server settings
  • Suspicious files indicating malware
  • Data leakage via unprotected directories
  • Weak user passwords
  • Misconfigured database credentials
  • SSL issues
  • Code injection risks

The scan produces a detailed report highlighting security flaws and the files affected. Some scanners even recommend fixes for issues discovery.

This allows you to take targeted action to patch vulnerabilities before hackers have a chance to exploit them.

Why WordPress Sites Need Vulnerability Scanning

WordPress powers over 40% of all websites, which makes it an extremely tempting target for hackers looking to spread malware, steal data or hijack traffic.

In fact, studies show over 70% of WordPress sites contain at least one serious vulnerability.

The main problem lies in keeping everything updated. With thousands of themes and plugins available, and new threats emerging daily, manual security monitoring quickly becomes unrealistic.

This leads to situations where threats go undiscovered for weeks or months, providing ample time for attacks.

A reputable vulnerability scanner continuously checks your entire site for weak spots, acting as an automated security monitoring system. The instant any issue emerges, you get alerted so patching can start ASAP.

Simply put – scanners boost security and let you fix flaws before hackers find them.

The Best WordPress Vulnerability Scanners of 2023

There are dozens of WordPress vulnerability scanners on the market, spanning free basic tools to advanced commercial platforms.

To help you identify the top options, I’ve compiled reviews of the 10 leading solutions across three categories:

  • Free online scanners – Allow quick scans but provide limited results
  • Premium scanners – Offer advanced scans and extra features for a paid fee
  • Security plugins – Integrate scans directly into your WordPress dashboard

Free Online WordPress Vulnerability Scanners

While handy for quick checks, free online scanners only scratch the surface in terms of depth of analysis and insight provided in their reports. Still, they can uncover common issues.

Sucuri SiteCheck

Sucuri offers a nicely balanced free online scanner that checks for malware, blacklisting status, directory listing risks and outsdated software.

What To Do Once Vulnerabilities Are Found

Discovering vulnerabilities is only step one. Quick patching is crucial before hackers sneak through openings.

Here’s a brief overview of how to address common WordPress security flaws uncovered by scans:

Outdated Software

Hackers love targeting outdated WordPress installs along with plugins/themes containing unpatched bugs. Simply update to the latest secure versions.

If updates aren’t available for abandoned plugins, remove them fully from your system.

Vulnerable User Accounts

Weak passwords lead to accounts being hijacked. Always use randomly generated 15+ length passwords.

Disable admin accounts fully if not needed. Limit administrator access only to trusted senior staff members.


Scanners pinpoint settings that undermine security, like allowing outbound connections from the DB or directory listing in web folders.

Carefully reconfigure options based on scanner suggestions to block threats from leveraging these openings.

Malware Infections

Signs of malware like strange files, suspicious redirects or unexpected code tweaks should be handled extremely urgently.

Use scanner file analysis capabilities to isolate and remove threats. In severe cases, restore your WordPress site from a known clean backup.

Exposed Sensitive Data

If scanners find admin pages or directories with database credentials, financial data or other sensitive materials exposed publicly, restrict access with password protection right away.

Prevent future leaks by enabling strict permissions on confidential assets.

The Importance of Continuous WordPress Scanning

With new threats constantly emerging, the only way to stay secure is through recurrent scans – at least twice per month.

This allows prompt discovery when any component like a plugin or OS server becomes outdated.

Certain premium scanners and plugins make continuous scanning simple by handling it automatically on preset schedules.

Monitoring scan results vigilantly also provides visibility if any unauthorized tampering occurs. Catching suspicious alterations early limits potential backdoor damage.

On top of scheduling recurrent scans, I recommend running new scans immediately after installing themes/plugins or making major WordPress configuration changes.

Keep Hackers Away With Reliable WordPress Vulnerability Management

I hope this guide has illuminated the immense value of leveraging WordPress vulnerability scanners as part of your website security strategy.

The top options allow proactive identification and patching of weaknesses before your site gets compromised. This saves enormous headaches down the road.

Whichever scanner you select, remember to keep it updated and scan frequently. Consistent protection repels the vast majority of hacker attacks targeting the widespread CMS.
