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.
AWS teams with S3 buckets exposed to multiple permission models will benefit most from S3cario's scenario-based testing, which catches permission misconfigurations that static policy reviewers overlook. The tool is free and requires no agent deployment, making it practical for teams running quick permission audits across dozens of buckets. Skip this if you need continuous compliance monitoring or CIEM-style access analytics; S3cario is a one-time assessment tool, not a runtime guardian.
