CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
AppSec engineers and penetration testers hunting SSRF vulnerabilities in staging or production will appreciate lorsrf's speed and CLI-first design; it catches out-of-band resource loads that static scanners routinely miss. At 296 GitHub stars with active commits, it's got enough traction to trust for routine testing workflows. Skip this if you need a GUI-based scanner or plan to integrate findings into a centralized SIEM; lorsrf is a lightweight specialist tool, not a platform replacement.
