The Best Application Security Testing Tools

There are several strategies for Application Security Testing (AST), and it can be challenging to work out which type you need for your enterprise. The first step in this task is to identify each kind of AST.

Look for:

  • DAST – Dynamic application security testing
  • SAST – Static application security testing
  • IAST – Interactive application security testing

There are only two types of testing systems: DAST and SAST. IAST is a combination of both DAST and SAST. Dynamic application security testing involves running the application, and static application security testing performs its tasks by analyzing the program’s code.

Here is our list of the best applications security testing tools:

  1. Aikido Security EDITOR’S CHOICE This cloud-based platform provides a range of security testing services that include software composition analysis, static application security testing, and dynamic application security testing units. The platform extends into production with CSPM and secrets detection, plus container and IaC scanning. Try it for free.
  2. GitLab Ultimate A CI/CD pipeline management package with a DAST system built. This is a cloud-based service.
  3. AppCheck This cloud-based service integrates with project management and issue tracking systems.
  4. Invicti A DAST package can also operate as a vulnerability scanner. This system can be integrated into a CI/CD pipeline, and it helps towards compliance with HIPAA and PCI DSS. Available as a cloud service or for installation on Windows or Windows Server.
  5. Acunetix An automated DAST system that is ideal for use by IT Operations technicians. It runs on Windows, macOS, and Linux.
  6. Checkmarx A cloud-based application testing platform that offers DAST and SAST services, which will give you an IAST if you combine the two plans. CI/CD pipeline integration makes this a good choice for DevOps teams.
  7. Veracode This cloud-based platform offers a range of application security testing services, including DAST and SAST packages. The company also has a penetration testing team.
  8. HCL AppScan DAST, SAST, and IAST options to test Web and mobile apps Offered as a cloud platform, but the software can also be self-hosted on Windows and Windows Server.

You can read more about each of these options in the following sections.

DAST is the only method that the users of commercial software can deploy. Without access to the code of an application, You are left with one option – run the software and test scenarios. This is a type of penetration testing or vulnerability scanning. The testing system starts with a list of known vulnerabilities and watches the operations of the application to see if that weakness exists.

SAST is a little like a QA check on code before it moves into acceptance testing, and it is part of unit testing. Like the DAST system, the SAST package has a list of weaknesses to look out for when reading through the program.

So, SAST is used for code verification, and DAST is used for acceptance testing. Businesses that produce commercial software need to make all efforts to ensure that the products do not include security weaknesses. This would consist of those companies that run SaaS platforms.

Software producers need to catch errors and weaknesses early to minimize the amount of rework that has to be done to fix the detected problem. So, the development team would use SAST. The marketers of that software and the technicians who will be supporting it once it is live need to perform DAST exercises to ensure no security problems in the system before it is made available to customers.

So, those businesses using both SAST and DAST would benefit from an application security testing package that performs both types of tests – an IAST system.

This is a very brief explanation of the meanings of DAST, SAST, and IAST. You can learn more about dynamic application security testing by looking at DAST (Dynamic Application Security Testing), including DAST tools. For a detailed explanation of static application security testing, could you read SAST (Static Application Security Testing), including SAST tools. Finally, you will find more information on interactive application security testing in What is IAST (Interactive Application Security Testing), including IAST tools? We have summarized their recommendations below if you have time to read the three reports.

The Best Application Security Testing Tools

When looking for an application security testing system, you need to look for services advertised as SAST, DAST, or IAST.

What should you look for in an application security testing tool for your business?  

We reviewed the market for ASTs and analyzed tools based on the following criteria:

  • A package that provides tools for manual testing and automated systems
  • A selection that includes on-premises tools and cloud-based services
  • The option to run tests on software that is still inaccessible to the outside world
  • Testing services that can identify when different modules have been called
  • A service that will integrate with project management and bug tracking systems
  • A free trial or a free demo for a risk-free assessment
  • Value for money, represented by a good set of tools at a reasonable price

With these selection criteria in mind, we looked for a range of AST systems suitable for all types of businesses.
