Top 10 Application Security Testing (AST) Tools

Top 10 Application Security Testing (AST) Tools

Building secure applications requires regular testing and patching of known vulnerabilities. AST tools help detect security loopholes, misconfigurations, and vulnerabilities in applications.

What is AST?

AST is the process of identifying and addressing security weaknesses to make the application resistant to security threats. This process helps firms identify security issues before the software moves to production. Businesses can conduct AST at any point during or after the application development.

Why Do Companies Need AST Tools?

  • To Enhance the Testing Speed and Maintain Remediation Workflow

Traditional code reviews and test plans are too slow and do not match the DevSecOps application development model. Hence, firms need AST tools that provide speed and scalability. Moreover, these tools offer remediation assistance, helping developers to save time and effort.

  • To Conduct Continuous Tests

Firms need a solid security testing workflow to test new features continuously. These tools will help stay updated with the emerging Common Vulnerabilities and Exposures (CVEs).

  • To Classify Vulnerabilities 

A robust AST tool will help prioritize and address vulnerabilities, help fix human errors, and authenticate vulnerabilities rapidly.

What Features an Ideal AST Tool Must Have?

The tool must:

  • Be convenient to use and have minimal features
  • Have reporting capabilities and offer reports per the regulations businesses follow.
  • Let companies understand the discovered vulnerabilities and allow configuring the scanner to email
