What is a Website Vulnerability Scanner?

Vulnerabilities can appear on websites due to weak user credentials or bugs in the coding of plugins or themes. Such security vulnerabilities on a WordPress website can be detected using a scanner.

Studies show that a leading cause for hacked websites is vulnerable themes and plugins installed on the site. To combat this, developers release vulnerability patches that come in the form of an update. You can check the most common WordPress security vulnerabilities here.

Website vulnerability scanners can detect which theme or plugin needs to be updated and alert users about it.

Another major vulnerability is the presence of malware on your website. Hackers inject malware or malicious codes into your website for several reasons. One big objective is to access your website whenever they please.

The presence of malware on your website makes your website vulnerable to repeated hack attempts.

A website vulnerability scanner helps you detect malware on your website. While there are many scanners that detect malware, only a few can find new and complex ones. Don’t worry, we went searching for the best online website vulnerability scan tools. And we have listed them down in the next section.

5 Best Online Website Vulnerability Scanners 

We tried dozens of tools to scan our websites and found 5 the following malware testing tools most effective.

1. MalCare Security Scanner

MalCare is the fastest vulnerability detection plugin.

The security team behind the plugin developed it from the ground up after analyzing more than 240,000 websites, MalCare is an unparalleled scanner that can detect common hack attacks like local file inclusion, SQL injections, command injection and wordpress xss attacks. Besides scanning,

MalCare also helps remove malware and offers a whole range of features to protect against future hack attempts.

MalCare Security Scanner

What Stands Out?

Identifies New & Complex Malware: MalCare has developed an intelligent scanning method that accurately identifies new and complex malware that other WordPress security plugins can’t detect. With MalCare malware scanner, there is no possiblity of false positives.

Daily Automatic Scan: The plugin scans your website once every 24 hours. This means you get notified immediately when malware is detected.

Doesn’t Overload Server: Plugins that run a security scan on your website server tend to slow down your site. But MalCare smartly copies your entire website to its own web servers and then run the scanning process without impacting your site performance.

2. Sucuri SiteCheck

Sucuri is probably the most popular website security scanner on our list. With Sucuri you can scan not only WordPress websites but also Joomla and Magento websites.

Sucuri SiteCheck

What Stands Out?

Detects Links Marked As “Not Secure”: Sometimes despite moving your site from HTTP to HTTPS, certain URLs of your website remain on HTTP. Google Chrome marks those links as “Not Secure.” Sucuri SiteCheck helps identify those links.

Detect Blacklist Status: The vulnerability scanner detect malware. And if your website has been blacklisted by any of the search engines because of malware infection, the scanner alerts you.

Checks for Pending Updates: Updates are released when vulnerabilities are found in a plugin, theme or the WordPress core. The scanner scans your site and alerts you when updates are pending.


  • Sucuri SiteCheck relies on pattern or signature matching methods that fail to detect new and complex malware. It can show your website as clean even when it’s infected with malware.
  • Sucuri will analyze your websites using a remote scanner which means malware embedded deep in your WordPress website goes undetected. Therefore malware exploits such as backdoors and phishing will be missed.

Quttera is another reputed website scanner that has been detecting website vulnerabilities for close to a decade. Other than WordPress websites, Quttera also scans Joomla, Drupal and Magento websites. It’s known to identify hack attacks like crosssite scripting xss, SQL injection, etc.


What Stands Out?

Detect Google & Yardex Blacklist Status: The scanner checks and alerts you if your websites are blacklisted by the two most popular search engines – Google and Yandex. You can read this guide on how to remove Google blacklist warning.

Assigns 4 Severity Types: After scanning your site, Quttera assigns any one of the following severity types: Clean, Potentially Suspicious, Suspicious, and Malicious.

4. Unmask Parasites

Unmask Parasites has a really minimal website. But don’t judge a book by its cover! It is a powerful online scanner that identifies web security threats on any WordPress website.

Unmask Parasites

What Stands Out?

Reveals Infected Web Pages: In certain types of hacks attacks like WordPress viagra hack, hackers insert malicious codes in many of the pages of the website. This scanner after running your website through its testing tools identifies and offers a list of these infected pages.

Reveals Spammy External Links: Every post or page that you publish on your website is likely to have one or more external links, i.e. links of other websites. But sometimes other websites are considered malicious. For instance, unknown to you, the external website could be selling illegal drugs. Unmask Parasites alerts you if you have linked to a malicious external website.


  • Unmask Parasites checks your website for known malicious codes. But some keywords like eval or base64_decode are found in both malicious and regular code. Therefore, the scanner can sometimes mark clean codes as malicious.
