Paros is a free dynamic application security testing tool. Acunetix Web Application & API Security is a commercial dynamic application security testing tool by Acunetix. Compare features, ratings, integrations, and community reviews side by side to find the best dynamic application security testing fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Acunetix Web Application & API Security
Mid-market and enterprise teams scanning high-volume web applications and APIs will get the fastest time-to-remediation from Acunetix Web Application & API Security because its proof-of-exploit feature eliminates the false positive triage work that burns through security resources. The blended DAST/IAST approach detects over 12,000 vulnerability types including zero-days, and scheduled continuous scanning catches drift in multi-environment deployments. Skip this if your main gap is secure code review or SAST; Acunetix prioritizes detection over identifying vulnerable code lines early in the pipeline, so developers won't get line-level guidance before deployment.
