CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Organizations hunting for exposed infrastructure across your full internet footprint should start with Binary Edge; its free tier lets you actually test passive DNS and exposed service discovery before committing budget, which matters because you need visibility before you can prioritize. The platform indexes over 3.5 billion internet devices and updates threat feeds in real-time, so you're not chasing yesterday's findings. This is weakest for teams that need active exploitation testing or vulnerability correlation tied to your internal asset inventory; Binary Edge tells you what's exposed, not whether your patching kept up.
Mid-market and enterprise security teams drowning in unmanaged external assets will see immediate ROI from StrikeOne Attack Surfa because its AI discovery actually finds forgotten cloud instances and third-party exposures your team doesn't know exist. The platform maps to NIST ID.AM and DE.CM, meaning you get asset inventory plus continuous monitoring in one workflow instead of bolting together disparate tools. Skip this if you need deep forensics or incident response integration; Surfa is purpose-built for surface discovery and anomaly detection, not post-breach investigation.
