Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management 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:
Security teams mapping external attack surface for web applications should start with Wappalyzer because it identifies technology stacks faster and cheaper than manual reconnaissance, and the free tier actually works without constant upsells. You get API access to scan hundreds of sites monthly, which beats the pay-per-lookup model competitors use. Skip this if you need continuous passive monitoring of your own infrastructure or vulnerability correlation baked in; Wappalyzer is a lookup tool, not a persistent scanner, so you're running point-in-time checks rather than feeding live asset data into your SIEM.
Enterprise security teams managing complex attack surfaces across subsidiaries, cloud environments, and critical infrastructure should pick Censys Internet Map for its ability to discover assets an organization doesn't know it owns, which is where most breaches actually start. The platform covers asset discovery and continuous monitoring across ID.AM and DE.CM in NIST CSF 2.0, and its internet-wide scanning capability surfaces shadow IT and unknown exposures that traditional vulnerability scanners simply cannot reach. Skip this if your primary need is incident response or forensics; Censys is built for prevention and reconnaissance, not post-breach analysis.
