The goal of an automated application security test is to scan your applications for flaws that cybercriminals may use to gain unauthorized access to your program's critical data. DAST tools come in two forms: paid and free. Free DAST Tools may not provide as many features or be as reliable, but they do provide some basic functionality which you might find useful if you're just starting out.
Paid DAST Tools will give you more features and better performance, but they also have higher price tags attached to them.

Astra's Pentest is a powerful tool for performing Dynamic Testing on web applications.

Astra is also one of the few Dynamic Testing tools that support both automated and manual testing.
Astra has free as well as paid versions. The free version includes features like Dynamic Analysis, Dynamic Fuzzing of Parameters, Detecting Vulnerabilities, and much more.
One of the most popular Dynamic Application Security Testing Tools, Acunetix offers a wide range of features that cover all aspects of application security. It has a built-in crawler that can crawl websites and Web applications for vulnerabilities, and it also includes an automatic vulnerability scanner. It uses the concept of "virtual patching", which means that it can automatically create and deploy custom patches without having to wait for the vendor's official release date. Acunetix has both paid & free versions.
3. Burp Suite
A very popular tool used by many penetration testers, Burp Suite is a Java-based platform that provides interception capabilities and dynamic analysis tools for testing web applications.

The IBM AppScan is a dynamic application security testing software that examines Java, .NET, and PHP applications for security flaws. It comes with a number of features, including both manual and automated scanning capabilities, vulnerability detection, and reporting.
