AppCheck Infrastructure Scanner is a commercial security scanning tool by AppCheck. Eagle is a free security scanning tool. Compare features, ratings, integrations, and community reviews side by side to find the best security scanning fit for your security stack.
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.
Developers and small security teams running manual penetration tests will find Eagle valuable for its multithreaded scanning speed, which processes web applications significantly faster than single-threaded alternatives without requiring licensing overhead. The free, open-source model with 126 GitHub stars indicates active maintenance and community validation for basic vulnerability detection workflows. Skip Eagle if you need authenticated scanning, API coverage, or integration with existing SAST/DAST pipelines; it's a lightweight scanner for low-complexity assessments, not a replacement for commercial web application firewalls.
