Types of Vulnerability Scanners 

1. Web Application Vulnerability Scanners

Web application vulnerability scanners scan one’s system to find vulnerabilities that could be hacked by a hacker to gain access to your website.  It reveals your web application’s vulnerabilities and prevents data breaches, identity theft, financial loss, and other negative consequences.

The scan searches for different vulnerabilities such as SQL injection, cross-site scripting, and cross-site request forgery. 

2. Network Vulnerability Scanners

Network vulnerability scanners check the security of a network to reveal any vulnerabilities that may leave the networks exposed and vulnerable to attacks. It maps out the networks, scans the network ports, and more. 

This type of scanning aims to find exploitable vulnerabilities in the system that outside parties could exploit. Network vulnerability scans are performed on the network infrastructure, also known as the backbone of the network.

3. Cloud Vulnerability Scanners

Cloud vulnerability scanners analyze a cloud computing environment for vulnerabilities that hackers could exploit. Cloud vulnerability scanning is a crucial component of a cloud security strategy because it can reveal potential weaknesses in cloud security controls.

4. API Vulnerability Scanners

 These vulnerability scanners identify vulnerabilities in an application programming interface (API). API vulnerability scanning scans the attack surface of an application by simulating the actions of a malicious user to identify any potential vulnerabilities that could be exploited by hackers. 

5. Mobile App Vulnerability Scanners

Mobile app vulnerability scanners scan a mobile application for security vulnerabilities. The goal of vulnerability scanning mobile applications is to find weaknesses in mobile security and report them to the developers.

5. Enterprise Vulnerability Scanners

These are vulnerability scanners that are extremely scalable and ideally suited for large companies with a multitude of assets. Such tools will also offer vulnerability management services as a part of their package to ensure a hassle-free vulnerability detection and remediation experience for customers. 

6. Open-Source Vulnerability Scanners

Open-source scanning software is free of cost and is perfect for new beginners and small companies alike to ensure the safety of their assets through continuous vulnerability scans.

How To Choose The Best Vulnerability Scanner? 

Here are the detailed factors to take into consideration when choosing the best vulnerability scanners.

1. Cost

Choosing according to the budget set you for your organization’s online security needs. The companies that you’re shortlisting should have the flexibility of setting a quote customized to your needs and or must have budget-friendly packages that are precise for your company size. 

2. Features

Analyze the features offered by each tool in your consideration to see which comes out as the winner. Some features to look for include: 

  1. Accurate Vulnerability Detection: It should be able to test and assess various types of assets for a wide range of vulnerabilities precisely. These assets could be web or mobile apps, to APIs, networks, and the cloud infrastructure.
  2. Continuous Scanning: The tool should continuously monitor and scan assets to find any hidden or new vulnerabilities that could have risen. 
  3. Vulnerability Management: Ensure that the vulnerability scanning provider does not leave you high and dry but rather has a vulnerability management function that deals with the detection and remediation of flaws. 
  4. Scalability: The tool should be scalable in terms of the assets that need to be scanned. 

3. Compliance

What are the compliances catered for by the tools within your consideration? Do they provide compliance-specific scans with tailor-made compliance reports based on the compliance you want to test for? Compliances like PCI-DSS, HIPAA, SOC2, GDPR, and ISO 27001 are some of the most important ones to keep in mind. 

4. Customer Support

Make sure that customer support provided by the vulnerability scanning provider in question is good with a quick query clearance rate. Check up on customer reviews and gain a better understanding of the customer support provided by the companies. 

5. Integrations

Can the tool be integrated with your CI/CD pipeline? This is crucial in the present-day scenario where due importance is being given to security in the online platform. Thus ensure that the tool you opt for can be integrated with your projects on different platforms. 

6. Detailed Reports

Ensure that tool provides a well-detailed report with CVSS-based risk scores explaining and summarizing the finding of the vulnerability scan based on the scope set by you and your scanning partner. 

Check out some of the sample reports provided by the companies on your shortlist to see which one is more detailed and goal-oriented and choose accordingly. 

Limitations of Vulnerability Scanners

Limitations of vulnerability scanners vary based on the features provided but in general, there are certain limitations for both pain and open-source vulnerability scanners. 

Limitations of Paid Vulnerability Scanners

  1. Not Extensive

A vulnerability scan can only detect the vulnerabilities but it does not provide an in-depth analysis of the damage that could be caused by it if the vulnerability was made used to gain entry by a malicious hacker. 

  1. Unclear Implications

Each vulnerability when exploited can expose different areas of your organization. A vulnerability scan cannot generally give a thorough understanding of the implication that a vulnerability has on your security system. 

3. Cost

Small businesses will find the costs of securing their websites with the aid of a commercial tool highly expensive. This is less applicable to medium and large enterprises. 

Limitations of Open-Source Vulnerability Scanners

  1. False Positives

Vulnerability scans can also result in false positives which in turn results in organizations spending time and money to fix vulnerabilities based on a glitch. 

  1. Limited Features

When it comes to the extensivity offered by a commercial vulnerability scanner, open-source tools fall short or rather will not have a great effect in terms of vulnerability detection. 

  1. Limited Updates

Most of the open-source vulnerability scanners have vulnerability databases that are not constantly updated meaning there it wouldn’t be able to detect newer vulnerabilities in assets. 

  1. Not scalable

Open-source vulnerability scanners are great for small companies and their assets. However, for large enterprises, the task of using an open-source tool can be tedious and cumbersome in terms of features, speed, and support. 

  1. No customer support

Although open-source vulnerability scanners are privy to large communities of dedicated cybersecurity experts, they do not have dedicated teams who can help you resolve queries and aid in remediation. 


This article has detailed the 17 best vulnerability scanners with Astra Pentest as the top contender, and their features, pros, and cons.

What can vulnerability scanners not do?

A vulnerability scanner provides an in-depth view of the impact of a vulnerability if it is exploited. Another issue with vulnerability scans is that it raises false positives which can result in companies spending time and money to fix vulnerabilities that didn’t exist. 

What are the advantages of vulnerability scanners?

Vulnerability scanners can help companies assess their security systems in a budget-friendly manner with continuous monitoring and fast results.

How does a vulnerability scanner detect threats?

Vulnerability scanners have a vulnerability database with all-known CVEs to which the vulnerabilities detected be matched for correct identification.
