The average data breach cost in 2021 was $ 4.24 million, up 10% from 2020. This cost includes the loss of business caused by the data breach, the cost of detecting and fixing the security issues that led to the breach, the cost of informing all the customers and rolling out the patches, and of course, the ensuing legal penalties.

A data breach is something that you would want to avoid at all costs. 

In this article, we will help you get familiar with some of the best web application security scanners and the various features offered by them. While we are at it, we will also refresh your knowledge of different types of web app scans, their benefits, and their importance. 

4 features you should look for in a web application vulnerability scanner

All vulnerability scanners come with some similar offerings – automated scans for your systems, an interface to monitor the scans, a vulnerability scan report, and a bit of assistance in terms of remediating the vulnerabilities. 

1. The scanner should fit inside your CI/CD pipeline

The importance of this feature cannot be stressed enough. Integrating a web application vulnerability scanner in the CI/CD allows you to automate vulnerability scans whenever there is a code update to be sent. This works on top of the scheduled automated scans that keep happening regularly.

2. You should have one place to control it all from

Just any dashboard doesn’t work. You need a dashboard that truly taps into every step of the vulnerability management process. From that one place, you should be able to  

  • Monitor the vulnerabilities  
  • Update their statuses
  • Assign them to team members
  • Discuss them with security experts

3. The vulnerability reports should be truly actionable

A vulnerability scanning report is just a bunch of text on a pdf file that no one reads unless it is designed for easy interpretation and actionability. If a vulnerability scanner offers you risk scores along with video PoCs of the vulnerabilities, go ahead and grab that tool.

4. The vulnerability scanner should make compliance easier

Compliance audits are the stuff of nightmares if you are not prepared for it, well, preparing for it is no walk in the park either.

Look for a vulnerability scanning tool that runs compliance-specific scans for you and tells you exactly what you need to fix in order to be more prepared for a certain compliance audit.

Benefits of regular web application vulnerability scanning 

More than 50 new CVEs were reported every day in 2020. This goes on to show how fast the cyber threat landscape evolves. That is why web app vulnerability scans have to be a continuous endeavor and not a one-time exercise.

Web application vulnerability scanner - benefits

Maintain a strong security posture

Maintaining and managing a strong security posture is essential for every web application to ensure the safety of its users. Regular vulnerability scans ensure that the security loopholes are periodically detected and remediated.

Never send a vulnerable update

Thanks to the emergence of DevOps, applications are developed and updated with great speed. Integrating a web application vulnerability scanner with the CI/CD pipeline of an application ensures that each new update is scanned for vulnerabilities before it goes live. 

Stay compliance ready

Compliance with relevant security regulations is extremely important for businesses to compete in the market and to build trust among their customers. Regular vulnerability scanning ensures that the security controls required for passing a compliance audit are in place. A vulnerability scan is a significant part of every compliance readiness program.
