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:
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.
AppSec teams running web application penetration tests or building secure development practices will get the most from Burp Suite Professional; its active scanning engine catches logic flaws and business logic vulnerabilities that static analysis misses entirely. The free Community edition has trained a generation of security practitioners and remains the de facto standard in security certifications like OSCP, so you're buying into an ecosystem with real staying power. Skip this if your priority is automated scanning at scale across hundreds of applications without manual tuning; Burp rewards hands-on operators more than it rewards fire-and-forget deployment models.
