SAST: How to Ensure Code Security Before You Even Run Your App

In app development, fixing vulnerabilities after the product is ready is expensive, slow and risky.
The good news? You can find and fix flaws even before running the software, using SAST – Static Application Security Testing.

What is SAST?

SAST (Static Application Security Testing) is an analysis technique that examines an application’s source code, bytecode or binary without running it.

It checks for vulnerabilities at the root of development, allowing problems to be detected early — and fixed at lower cost.

How does SAST work?

The developer writes the application code
The SAST tool analyzes the code looking for dangerous patterns
Vulnerabilities and bad practices are listed in a report
The team fixes them before the testing or execution phase

It is like reviewing a building’s architectural plan before construction, making sure there are no structural flaws.

✅ Benefits of SAST

Early detection of critical flaws
Lower fix costs
Compliance with standards such as OWASP, LGPD and ISO 27001
Continuous improvement in code quality
Integration with CI/CD pipelines to automate security

⚠️ Examples of vulnerabilities SAST can find

SQL Injection
Cross-Site Scripting (XSS)
Unsanitized variables
Sensitive data exposure
Insecure logic in the code

Recommended tools and practices

Tools such as Verimatrix, SonarQube, Checkmarx, Fortify and Snyk are widely used for SAST, but effectiveness also depends on:

Training the team in secure development
Applying code reviews
Adopting secure coding standards

How Pluritech uses SAST in its projects

At Pluritech, SAST is part of a secure development culture.
Even before an app is tested in a real environment, we apply static analysis to make sure that:

The code is clean and free of critical flaws
Security best practices are applied
The client receives a product with top-level quality and security

Conclusion

SAST is not just a tool — it is a preventive strategy that reduces risk, saves time and raises the final quality of the software.
