What Is the Difference Between SAST, DAST, and IAST?

What benefits does SAST have? What's the difference between SAST and DAST? What's IAST? What do all these words mean?! Let's talk about this and more in the overview of the main types of Application Security Testing (AST).

As a result, the number of possible vulnerabilities and errors is increasing as well. This creates the need for effective checking and testing of the source code.

Why You Need Static and Dynamic Application Security Testing in Development Workflows

DevOps is a quickly growing practice for companies in almost every market. With the influx of cyberattacks over the past decade, security has slowly crept forward in the SDLC to the point where we’re now hearing the term DevSecOps in developer circles.

To keep things tidy and help developers manage additional security responsibilities, tools for static and dynamic application security testing (SAST and DAST) have made their way into the fray. In this post, we’ll explain what SAST and DAST are, how they fit into developers’ workflows, and when they should be used.
