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.
Teams managing AWS infrastructure who need to catch credential leaks before they become incidents will find Dufflebag's focus on public EBS snapshots invaluable; it hunts a blind spot most scanners skip entirely. The free pricing and 299 GitHub stars signal active community validation of the detection logic. This is not for organizations needing a managed service with incident response integration or compliance reporting; Dufflebag is a scrappy, self-operated tool that rewards teams willing to run it themselves and act on findings quickly.
