Features, pricing, ratings, and pros and cons, compared head to head.
Fortra BeSTORM is a commercial dynamic application security testing tool by Fortra. w3af 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. Teams building internal web applications or running security labs will find w3af's strength in its coverage of injection attacks and XSS variants, which accounts for the majority of real web vulnerabilities teams actually need to catch first. At 4,852 GitHub stars with active open source maintenance, it stays current with emerging payloads without vendor lock-in costs. Skip this if your security program requires managed support, compliance reporting, or integration with your existing SAST pipeline; w3af is a scanner you operate yourself, not a service that integrates upstream.
Based on our analysis of core features, company size fit, deployment model, here is our conclusion:
