Automated Security Testing for Applications: Top Tools and The Benefits

04.01.21 By

Gone are the days when a web application meant a website. The explosive adoption of cloud and mobile have paved the way for new use cases including payroll systems, marketplaces, banking, and stock trading and more. Besides ease of use and convenience, application security is of paramount importance in maintaining customer trust as most web applications receive and utilize personal information. A robust security testing program is critical to ensure customer PII is protected.

In this blog, we will focus on application security testing methods, their benefits, and some of the top automated security testing toolsets available.

API Security Testing

Application Programming Interface (API) security testing ensures software applications are secure at the code level. Ensuring that APIs are error-free helps avert hackers. This is accomplished through Fuzz Testing, Penetration Testing and Security Testing. API testing:

  • works independent of the technology used to develop applications
  • is cost-effective as it reduces risks in the later stages of development
  • ensures that software code quality is maintained throughout the development and testing cycle
  • is less time-consuming as compared to functional or validation testing

Setting up Automated Tests to Authenticate Scenarios

The need to authenticate scenarios is an important step in security testing. It allows software developers and testers to walk through the actual user experience and journey while using the application. Each movement a user would take in the application is reviewed and then tested. This is an important step in determining the significance and nuances to be followed while creating test scenarios and authenticating them.

Advantages of Automated Security Testing

Manual security testing is generally completed towards the end of the software development cycle. It can be a cumbersome process that could invite unnecessary shortcomings. Automation in security testing is best achieved at the beginning of the development cycle and offers several advantages.

  • Bugs and errors are discovered early in the development cycle, revealing possible threats
  • Simplified resolution of application bugs, errors, malfunctions, and anomalies
  • Reduced threat to application delivery schedules as risks of malfunction are reduced
  • Flexibility to integrate with systems for CICD pipelines
  • Easy script maintenance
  • Joint ownership and collaboration of software developers and testers in reducing security debt

Top Five Open Source Automated Security Testing Tools

The automated tools market is filled with a plethora of options. Besides assuring application security is solid, they offer the ability to significantly reduce the manual labor and time involved in security testing.

The tool selection process depends heavily on your organizational requirements and priorities. The right tool, however, should be user friendly, easy to understand, well documented and offer seamless CI/CD integration. It should also provide application insights and report options that help your testing team reduce the amount of false positive results while testing.

Which toolset is best for you? Each tool provides a slightly varying degree of functionality. The right tool will be determined by your specific requirements including your business and technology needs, project, team, budget, and other such factors.


The significance of API security testing is growing every day. With the increasingly rising concern of exposed user data, the protection and security of applications has become paramount. By identifying vulnerabilities early in the software development process, engineers can categorize these vulnerabilities and defend against them by creating diverse scenarios. The use of automated tools enhances both the quality and agility in your application security testing programs.
