Binary Edge vs Bitsight External Attack Surface Management: 2026 Comparison

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.
