Security Scanner

Have you found a sudden slowdown on your website? Have you come across any odd pop-ups on your website? Do you have suspicions that your website has been hacked? Is your Adwords account with Google suspended? It’s possible that your assumptions are right! These are the telltale signs of a hacker. You can use a website vulnerability detector to see if your site has been compromised.

There are several online scanners from which to choose. However, each scanner is constructed differently.

Some people still use old techniques, while others have created modern ones.

We looked at the most common scanners on the market to see which ones are based on old technology and which ones are built on modern technology.

We were able to distil the most powerful website vulnerability scanners available today as a result of this process.

We went through the scanners in depth in this post in the hopes of making it easier for WordPress website owners to select the right web scanner.


If you need a website vulnerability scanner quickly, we recommend downloading and installing MalCare Vulnerability Scanner. It will search your website and remove any malware that might be lurking there. The plugin will even assist you in cleaning your website and protecting it from hacking attempts.

What is a Website Vulnerability Scanner?

Vulnerabilities may occur on websites as a result of insecure user credentials or bugs in plugin or theme coding. A scanner can detect certain security vulnerabilities on a WordPress website.

According to reports, insecure themes and plugins built on the site are a leading cause of hacked websites. To combat this, software developers submit vulnerability fixes in the form of software updates. You will find a list of the most popular WordPress security flaws here.

Website vulnerability scanners may detect which themes or plugins need updating and notify users.

The appearance of malware on your website is another big weakness. For a number of purposes, hackers inject malware or malicious codes into your website. One major goal is for people to be able to access the website anytime they want.

When malware is present on your website, it makes it vulnerable to repeated hacking attempts.

You can use a website vulnerability scanner to detect malware on your site. Although several scanners can detect malware, only a few are capable of detecting new and complex threats. We looked for the best online website vulnerability scan tools, so don’t worry. We’ve compiled a list of them in the following section.

5 Best Online Website Vulnerability Scanners

We tested hundreds of tools to search our websites and found that the five tools mentioned below were the most successful.

MalCare Security Scanner

MalCare is the most rapid vulnerability detection plugin on the market.

MalCare is an unrivaled scanner that can detect popular hack attacks including local file inclusion, SQL injections, command injection, and WordPress XSS attacks, thanks to the security team behind the plugin who designed it from the ground up after analyzing more than 240,000 websites. Aside from scanning,

MalCare also assists in the removal of malware and provides a number of features to guard against potential hacking attempts.

What Stands Out?

MalCare has developed an intelligent scanning tool that reliably detects new and complex malware that other security plugins are unable to identify. There are no false positives with the MalCare malware scanner.

Daily Automatic Scan: Once every 24 hours, the plugin scans your website. This means you’ll be alerted as soon as malware is identified.

Doesn’t Slow Down Your Site: Plugins that run a security check on your website server will cause your site to slow down. MalCare, on the other hand, copies your entire website to its own web servers and then scans it without affecting its results.


Local websites built on your device are inaccessible to MalCare’s malware scanner.


MalCare Security Scanner is fully free software.

Sucuri SiteCheck

On our list, Sucuri is probably the most common website security scanner. Not only WordPress but also Joomla and Magento websites can be searched with Sucuri.

What Stands Out?

Detects “Not Secure” Links: Even after switching your website from HTTP to HTTPS, some URLs can still be on HTTP. Those links are marked as “Not Safe” in Google Chrome. Sucuri SiteCheck aids in the detection of these connections.

Blacklist Status Detection: Malware is detected by the vulnerability scanner. The scanner will also warn you if your website has been blacklisted by any search engines due to malware infection.

Checks for Pending Updates: When bugs in a plugin, theme or the WordPress core are discovered, updates are published. The scanner checks your site and notifies you of any pending updates.


Pattern or signature matching methods used by Sucuri SiteCheck fail to detect new and complex malware. Even if your website is contaminated with malware, it will appear to be clean.
Sucuri will use a remote scanner to analyze your websites, which means malware concealed deep inside your WordPress pages will go undetected. As a result, malware attacks like backdoors and phishing can go unnoticed.


Sucuri SiteCheck is a completely free service.


Another well-known website scanner is Quttera, which has been detecting website vulnerabilities for nearly a decade. Quttera scans Joomla, Drupal, and Magento websites in addition to WordPress pages. It has been used to detect hack attacks such as cross-site scripting (XSS), SQL injection, and others.

What Stands Out?

Offer Malware Assessment Report: After scanning your website with Quttera, if the scanner detects a malware, it will produce a report on the threats discovered.

Detect Google and Yardex Blacklist Status: The scanner tests and notifies you if your websites are blacklisted by Google and Yandex, the two most common search engines. This article will show you how to delete the Google blacklist alert.

Quttera assigns one of four severity forms after scanning your site: Clean, Potentially Suspicious, Suspicious, or Malicious.


Quttera is incapable of searching large websites. It is unable to search websites larger than 20MB.
When a large number of people use the free scanner at the same time, the scanning process will take a long time to complete.


The Quttera Website Scanner is available for download.

Unmask Parasites

Unmask Parasites’ website is extremely easy. However, never judge a book by its cover! It’s a robust online scanner that can detect web security threats on any WordPress site.

What Stands Out?

Shows Infected Script: When a website is compromised, hackers normally insert malicious code into the site’s files and directories. Unmask Parasites reveals the malicious codes or scripts that are currently active on your website.

Hackers inject malicious codes in many of the pages of the website in some forms of hacking attacks, such as pharma hacking. After running the website via its testing software, this scanner detects and displays a list of infected sites.

External Links: Any article or page you publish on your website is likely to contain one or more external links, which are links to other websites. Other websites, on the other hand, are sometimes viewed as malicious. For example, the external website may be selling illegal drugs without your knowledge. If you connect to a malicious external website, Unmask Parasites will warn you.


Unmask Parasites scans your website for malicious code that has previously been identified. However, some keywords, such as eval and base64 decode, can be used in both malicious and non-malicious code. As a result, the scanner can mistakenly recognize clean codes as malicious.
The scanner provides you with codes that appear to be suspicious. However, you’ll have to find out which files are malicious and then delete them.


Unmask Parasites is fully free software.

UpGuard Web Scan

UpGuard is a cybersecurity agency that is well-known for sharing information regarding data breaches. Some of their work has been featured in publications such as Forbes and Techcrunch.

What Stands Out?

UpGuard conducts a vulnerability test on your website that involves over 30 security tests, including the existence of phishing sites, ransomware, compromised applications, and more.

The web vulnerability scanner assigns a score to your website’s overall security health based on the results of the security search. If your site’s rate is less than 500, it’s weak and easy to hack.

Detects the following hacks that your site is vulnerable to: The scanner looks for security flaws on your site. It informs you about the types of hack attacks that can occur on your website based on the security holes present on your site.


UpGuard is unable to detect new or complex malware on a WordPress website that has been compromised.
The scanning method takes a long time to display the results of the scan.
Furthermore, we had to run the scanner three times before it could show the scanning results.


UpGuard Web Scan is completely free.

That’s all there is to it, folks. These are the best online website scanners for detecting security flaws on your site.

You’ll need to clean up your site after finding malware. Additional security measures, such as installing an SSL certificate and protecting the login page, will be needed.

Last Thoughts

Malware and other bugs can be found by using online website scanners. They do, however, have disadvantages.

Since these scanners are positioned remotely, they are unable to conduct deep scans on a website. As a result, they miss a lot of malware that is covered.

Not only that, but these website vulnerability scanning tools do not automatically search the site. You must start a scan, which is uncomfortable. A website should be scanned on a regular basis, and it’s best to automate the process.

These vulnerabilities are not present in the MalCare Website Security Plugin. It’s one of the most widely used security software on the market. Every day, the plugin performs an automatic security check on your website. It also scans every file and folder on your website for hidden malware.

Not only that, but MalCare’s site hardening feature protects the website from common security flaws. It also has a firewall that prevents bad IP addresses from accessing your domain.
