Features, pricing, ratings, and pros and cons, compared head to head.
Fortra BeSTORM is a commercial dynamic application security testing tool by Fortra. Paros is a free dynamic application security testing tool. Compare features, ratings, integrations, and community reviews side by side to find the best dynamic application security testing fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
Enterprise and mid-market security teams with mature CI/CD pipelines will get the most from Fortra BeSTORM because its black box fuzzing approach catches logic flaws and authentication bypasses that static scanners routinely miss during pre-deployment testing. The tool's hybrid deployment model and alignment with NIST ID.RA (risk assessment) means it integrates cleanly into existing risk workflows without forcing rip-and-replace decisions. Skip this if your organization runs heavy manual penetration testing or lacks the engineering bandwidth to tune fuzzing parameters; BeSTORM demands active tuning to avoid noise, and passive buyers end up drowning in low-confidence findings. Development teams and pentesters evaluating web application security on a zero budget should pilot Paros; its Java-based proxy architecture handles manual and semi-automated vulnerability discovery without licensing friction, making it ideal for teams building testing workflows before committing to commercial DAST. The tool has been actively maintained for nearly two decades and integrates cleanly with CI/CD pipelines for teams willing to script around its GUI. Skip Paros if you need automated scanning at scale, machine-learning-driven payload generation, or support for modern API authentication schemes; it's a manual-heavy framework that demands operator expertise to extract full value.
