Security teams at startups and SMBs who need unlimited IP scanning without per-asset licensing will find Nessus Professional the most cost-effective entry point to credentialed vulnerability assessment. The continuously updated plugin library and support for air-gapped environments mean you're not locked into cloud connectivity or paying overage fees as your infrastructure grows. Skip this if your organization needs integrated threat intelligence, remediation orchestration, or multi-tenant management; Nessus Professional is purpose-built for vulnerability discovery, not response automation.
Startup and SMB security teams without dedicated vulnerability management programs should start with RoboShadow; its one-click remediation through integrated RMM actually closes findings instead of just reporting them. The platform covers both ID.AM asset discovery and RS.MI incident mitigation across internal and external surfaces, backed by integrations with Active Directory and Microsoft's ecosystem that most smaller shops already run. Skip this if you need deep threat intelligence feeds or advanced persistent threat hunting; RoboShadow is built for speed and simplicity over investigative depth.
