Amass is a free external attack surface management tool. Binary Edge is a free external attack surface management tool. Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack.
Based on our analysis of available product data, here is our conclusion:
Security teams building reconnaissance automation into their reconnaissance workflow should start with Amass because it outperforms commercial tools at subdomain enumeration speed and catches assets that paid solutions miss through its multi-source passive collection approach. The 14,260 GitHub stars reflect sustained adoption by practitioners who've validated it against their own external asset inventories. Skip this if you need managed threat intelligence feeds, API-based asset tagging, or risk scoring; Amass is a discovery engine, not an asset management platform.
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.
Amass is an open-source OWASP tool for comprehensive attack surface mapping and asset discovery through domain reconnaissance and subdomain enumeration.
A platform providing real-time threat intelligence streams and reports on internet-exposed assets to help organizations monitor and secure their attack surface.
