CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Startups and SMBs that need visibility into external-facing infrastructure without managing agents should start with Halo Security Server Scanning. The agentless model means you're scanning production servers within minutes of signup, and the real-time Slack alerting actually gets findings in front of the right person before they disappear from memory. This tool prioritizes detection over remediation tracking, so teams expecting tight ticketing integration or drift remediation will need to bolt on a separate system.
Bug bounty hunters and penetration testers doing initial reconnaissance will move faster with Naabu than commercial alternatives; it's written in Go for speed and handles the messy work of discovering what's actually listening without the setup tax of enterprise scanners. The 5,400-plus GitHub stars reflect real adoption in the offensive security community where execution time and accuracy matter more than GUI polish. Skip this if you need centralized asset inventory, compliance reporting, or integration with a broader vulnerability management platform; Naabu is a single-purpose tool that excels at what it does and stops there.
