What Are SAST Tools?
SAST (Static Application Security Testing) tools are specialized software that is designed to automatically analyze the source code of an application and identify potential security vulnerabilities. These tools use static analysis techniques to examine the source code, looking for patterns and anomalies that could indicate a vulnerability.
For example, a SAST tool might look for hard-coded sensitive data, unvalidated input, or insecure coding practices that could be exploited by attackers. SAST tools can provide detailed information about the specific lines of code where vulnerabilities are located, so that developers can fix the problems and improve the security of the application. SAST tools are typically used early in the development process, before the application is deployed.

Key Considerations When Choosing a SAST Tool
False positives are one of the main factors that can impact the accuracy of a SAST tool. A false positive occurs when the tool identifies a potential vulnerability in the source code, but the identified vulnerability is not actually present. This can be frustrating for developers, who may spend time and effort investigating and fixing a problem that does not exist. A tool with a high rate of false positives will have a lower level of accuracy, as it may miss actual vulnerabilities or generate a large number of false alarms.
Vulnerability databases and threat intelligence feeds can also impact the accuracy of a SAST tool. Many SAST tools use databases of known vulnerabilities and threat intelligence feeds to identify potential security issues in the source code. The accuracy of the tool will depend on the quality and completeness of these databases and feeds. A tool that uses outdated or incomplete information may miss vulnerabilities or generate false positives, reducing its overall accuracy.
Language Coverage and Versatility
Language coverage refers to the number and types of programming languages that a SAST tool can analyze. A tool with broad language coverage is able to analyze a wide range of languages, including common ones like Java, C++, and Python, as well as less commonly used languages. This allows the tool to be used on a wider variety of projects and codebases, increasing its effectiveness.
Versatility determines a SAST tool's ability to be integrated with different development environments and processes. A versatile tool can be easily integrated into a variety of development workflows, allowing developers to use it without disrupting their existing processes. This can make the tool more effective, as it can be used more easily and consistently by the development team.
API Structure and Ease of Integration
A well-designed API structure allows the tool to be easily integrated with other tools and systems, improving its overall effectiveness. For example, a SAST tool with a clear and well-documented API can be easily integrated with a continuous integration/continuous deployment (CI/CD) pipeline, allowing it to be used automatically and consistently as part of the development process.
Speed of Scan
A slow-scanning SAST tool can be frustrating for development teams, as it may take a long time to analyze the code and identify vulnerabilities. This can slow down the development process and disrupt the team's workflow, which can be frustrating. A slow-scanning tool may also miss vulnerabilities that are introduced or fixed during the scan, reducing its effectiveness.
On the other hand, a fast-scanning SAST tool can help teams to quickly identify and fix security vulnerabilities in their code, improving the overall security of their software. This can be particularly useful for teams working on large codebases or on tight deadlines, as it allows them to find and fix vulnerabilities quickly and efficiently.
