Static Application Security Testing (SAST) is a process that involves directly analyzing an application's source code during the early stages of development to identify vulnerabilities and weaknesses that may pose future security risks.

SAST works by scanning the source code, binaries, or bytecode without executing the application. This allows issues to be identified early in the development process, such as:

• Variables that are used without proper validation.
• Insecure data handling practices.
• Calls to high-risk functions.
• Code that may be susceptible to injection or privilege escalation.

SAST is ideal for organizations aiming to integrate security into the development process (DevSecOps) and looking for a fast, in-depth, and comprehensive approach to security testing that covers every line of code. It enables developers to write secure code with confidence and ensures applications are protected before being deployed in real-world environments.
