CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Acunetix Web Vulnerability Scanner
Development and security teams managing public-facing web applications will get the most from Acunetix Web Vulnerability Scanner because its crawling engine finds logic flaws and chained vulnerabilities that static scanners miss. The tool catches real exploitable paths through your site, not just isolated weaknesses; a single scan typically surfaces 40+ issues on medium-sized applications. Skip this if you need API-first scanning or are hunting for code-level defects in your build pipeline; Acunetix is purpose-built for runtime web application testing, not SAST or microservices architecture assessment.
Startup development teams shipping fast need Perisai Web Scanner because it catches vulnerable dependencies and misconfigured headers in minutes without requiring infrastructure changes. The free tier covers automated scanning across JavaScript libraries and HTTP security posture, removing the cost barrier that usually delays security scanning adoption. Skip this if you're managing legacy monoliths with hundreds of interconnected services or need continuous runtime monitoring post-deployment; Perisai maps application risk at scan time, not in production.
