Features, pricing, ratings, and pros & cons — compared head-to-head.
PAPIMonitor is a free dynamic application security testing tool. Start Left® Security DAST is a commercial dynamic application security testing tool by Start Left® Security. Compare features, ratings, integrations, and community reviews side by side to find the best dynamic application security testing fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mobile security engineers who need to inspect API calls in Android apps during dynamic testing will find PAPIMonitor's Frida-based approach faster than manual instrumentation or proxy interception. The tool is free and lightweight enough to run on modest hardware, making it accessible for small security teams or researchers without budget for commercial DAST platforms. Skip this if your team lacks Python fluency or needs to test iOS apps; PAPIMonitor is Android-specific and requires hands-on scripting to define which APIs to monitor.
Mid-market and enterprise teams shipping code through active CI/CD pipelines should choose Start Left® Security DAST for real-world attack simulation against live applications before production deployment. The tool integrates directly into pipeline workflows and prioritizes vulnerabilities by actual business impact rather than raw severity scores, which cuts triage time for teams managing large application portfolios. Start Left® Security DAST is weaker on NIST ID.RA (risk assessment) automation compared to static analysis tools that map findings to asset inventories, so it works best paired with complementary risk management processes rather than as your sole risk quantification engine.
