CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:

crawley

Security teams building custom reconnaissance workflows or integrating web discovery into existing automation pipelines should start with Crawley; it's free, written in Go for speed, and handles multiple protocols and authentication methods that most off-the-shelf crawlers require workarounds to support. The 308 GitHub stars reflect active maintenance and real-world use rather than enterprise polish. Skip this if you need a GUI, managed hosting, or out-of-the-box reporting; Crawley is deliberately a building block, not a finished product.
