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, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams with sprawling web applications and APIs across multiple clouds will get the most from Qualys TotalAppSec because its AI-assisted clustering actually reduces scan overhead on large attack surfaces instead of just generating more noise. The tool covers OWASP Top 10 and API Top 10 with continuous monitoring and integrates third-party pen test findings from Burp and BugCrowd, which means you're not rebuilding your threat picture across disconnected tools. Skip this if your priority is SAST or supply chain scanning; Qualys TotalAppSec does runtime application security well but doesn't shift left into code repositories.
Mid-market and enterprise teams building APIs or JavaScript-heavy web apps need Probely (Snyk API & Web) because it actually discovers what you're running before it scans it, eliminating the guesswork that kills DAST programs. The headless Chrome spider handles modern SPAs and the native API scanning accepts OpenAPI and Postman Collections directly from your existing tooling, cutting weeks off typical deployments. Skip this if your primary concern is SAST or supply chain risk; Probely owns the runtime security layer (NIST ID.RA and PR.PS) but doesn't pretend to be your code scanner.
