CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
AppCheck Infrastructure Scanner
SMBs and mid-market teams without dedicated vulnerability management staff should pick AppCheck Infrastructure Scanner for its unlimited scanning and users, removing seat-based licensing friction that kills adoption. The proprietary VulnFeed database detects over 20,000 products and tens of thousands of CVEs with authenticated scanning that catches what surface-level tools miss, and RBAC plus role-based reporting let security generalists delegate tasks without handing out admin access. Skip this if your primary need is web application scanning; the infrastructure focus is strong, but the web scanning is secondary to the core network and data center mission.
DevOps and AppSec teams who need to scrub secrets from Git history before they leak will find Nosey Parker essential; it's one of the few free tools that actually scans committed code retroactively instead of just catching new commits. With 2,039 GitHub stars and active maintenance, it's proven reliable enough that teams regularly integrate it into CI/CD pipelines for pre-push validation. Skip this if you need a polished UI or real-time monitoring across multiple repositories at scale; Nosey Parker is command-line only and requires engineers comfortable scripting their own automation.
