Features, pricing, ratings, and pros & cons — compared head-to-head.
Perisai Web Scanner is a free security scanning tool by Peris.ai. dns-parallel-prober is a free security scanning tool. Compare features, ratings, integrations, and community reviews side by side to find the best security scanning 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:
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.
Security teams running large-scale reconnaissance or validating DNS infrastructure will value dns-parallel-prober for its adaptive parallelization, which outpaces sequential probing when querying hundreds of domains simultaneously. The 108 GitHub stars and proof-of-concept maturity indicate it's battle-tested by practitioners, not marketed vaporware. This is a PoC, though, so skip it if you need vendor support, SLA guarantees, or integration with commercial scanning platforms; it's built for operators comfortable reading source code and tuning parameters themselves.
