You need a vulnerability scanner to protect your assets, but finding the right one can be overwhelming.

It's critical to ensure that the tool you choose reduces frustrations among your IT team, developers, and security department and works with them.

This article will cover the top five best vulnerability scanners on the market today—helping you find the right tool for your security needs.

What Is a Vulnerability Scan?

You should know what to expect from a vulnerability scan before making a decision.

Vulnerability scans detect and report weaknesses in a network, web application, or API that hackers can exploit.

The reports generated from the scans allow your IT team to regularly patch your vulnerabilities, protecting your most sensitive data.

1. APIsec

APIsec is a vulnerability scanner that offers full coverage API scanning and automated testing designed to keep up with your fast-paced business.

Most API security testing tools require you to manually write thousands of test cases. APIsec is the only AI-based solution that writes tests for you, allowing you to fully automate the entire API security testing process.

It identifies loopholes regardless of the size and complexity of your API, including business logic flaws (an aspect other scanners often overlook that allows hackers to abuse the legitimate functionalities of your API) before hackers have the chance to exploit them.

Top Features

  • Full Coverage: APIsec learns the ins and outs of your API once it is integrated into your system, discovering exactly how it is used and where weaknesses may occur.
  • Automatic Testing: The scanners run continuous, comprehensive tests that cover a wide range of vulnerabilities, including the OWASP Security Top 10 list.
  • API Pen Tests: APIsec simulates attacks on your API, ensuring its every aspect is secure from potential hacks.
  • Business Logic Flaws: APIsec leverages the power of AI to deeply understand how your API works, making it possible to uncover business logic vulnerabilities - one of the most dangerous types of cyberthreats that typically slip through the cracks.
