Compare the Top Free Application Security Software as of October 2025

What is Free Application Security Software?

Application security software is designed to protect applications from cyber threats by identifying vulnerabilities, preventing attacks, and ensuring data integrity throughout the application’s lifecycle. This software typically includes features like static and dynamic analysis, runtime protection, and vulnerability scanning to detect and address potential security issues such as SQL injection, cross-site scripting (XSS), and unauthorized access. It helps organizations maintain secure applications by implementing best practices for secure coding, performing penetration testing, and monitoring for security breaches. Application security software is crucial for organizations to safeguard sensitive data, comply with regulations, and minimize the risk of exploitation.

    Jit

    Jit

    DevOps ain’t easy! We are hearing more and more about the breakdown and friction where Dev meets Ops, so let’s not even talk about all the other shift-left domains that add another layer of complexity in the middle like DevSecOps. Where this comes with the need to implement and integrate dozens of security tools in their SDLC. But what if it doesn’t have to be difficult? Jit's DevSecOps Orchestration Platform allows high-velocity Engineering teams to own product security while increasing dev velocity. With a unified and friendly developer experience, we envision a world where every cloud application is born with Minimal Viable Security (MVS) embedded and iteratively improves by adding Continuous Security into CI/CD/CS.

    Contrast Security

    Contrast Security

    Contrast Security

    Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.

    ActiveState

    ActiveState

    ActiveState

    ActiveState delivers Intelligent Remediation for vulnerability management, which enables DevSecOps teams to not only identify vulnerabilities in open source packages, but also to automatically prioritize, remediate, and deploy fixes into production without breaking changes, ensuring that applications are truly secured. Existing tools overwhelm DevSecOps teams with excessive vulnerability data, false positives, and a lack of prioritization, often leading to inaction and increased exposure to exploits. ActiveState’s solution provides your DevSecOps with a comprehensive view of open source vulnerability status across your application portfolio, enabling them to prioritize the vulnerabilities that matter, assess the risk of updates, and choose recommended remediation paths. The ActiveState platform centers on open source languages packaged as runtimes that can be deployed in various form factors. Low-to-no CVE container images are also available for plug-in and play needs.
