Best SAST Solutions: How to Choose Between the Top 11 Tools in 2025 Static Application Security Testing (SAST) is a proactive approach to identifying security vulnerabilities in source code during development. This article delves into the core features of SAST tools, reviews leading solutions, and provides guidance on selecting the right tool to enhance your software’s security posture.

Daniel Pouzzner from wolfSSL has challenged us to find 3 more vulnerabilities in the wolfSSL library, after we found the first one in October 2024. We weren't quite able to find three, but here are the additional two that we found: Both vulnerabilities were fixed in wolfSSL version 5.8.0, released on 24 April 2025. The fuzz tests that found these vulnerabilities were generated by our AI Test Agent.

SAST tools automatically scan the source code of an application. The goal is to identify vulnerabilities before deployment. SAST tools perform white-box testing, which involves analyzing the code based on inside knowledge of the application. SAST offers granularity in detecting vulnerabilities, providing an assessment down to the line of code.

If you recognize the benefits that fuzz testing can bring to your software security but are new to it, read on. In this blog post, you’ll learn what you need to consider before implementing fuzz testing in your company to ensure a smooth and successful adoption. So, you’ve chosen the light side and decided to find and fix bugs in your code before they become a problem. Well done, and congrats!

Securing your applications is vital in today’s fast-moving world of software development. With threats constantly getting smarter, developers need strong tools to identify and fix weaknesses right from the start. Just ask Alex, a developer who once spent a sleepless night fixing a last-minute security flaw. That’s where Veracode SAST comes in. This powerful tool not only scans your source code and binary files but also integrates seamlessly with your IDEs, repositories, and CI/CD pipelines.

Static application security testing (SAST) has matured from a gate-at-the-end to a developer-first discipline. Forrester’s Static Application Security Testing (SAST) 2025 landscape report highlights why: attack volume is rising, code is released at least monthly in one in four teams, and AI generated code is flooding pipelines with even more code to secure. The tools that succeed are those that shorten mean time to remediate (MTTR) while fitting the way modern teams build.

DAST is a security tool that attempts to penetrate an application from the outside by checking its exposed interfaces for vulnerabilities and flaws. Sometimes called a web application vulnerability scanner, it is a type of black-box security test. It looks for security vulnerabilities by simulating external attacks on an application while the application is running.
