Features, pricing, ratings, and pros and cons, compared head to head.
Amass is a free external attack surface management tool. Searchlight Exposure – Exposure Management is a commercial external attack surface management tool by Searchlight Cyber. Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
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. Mid-market and enterprise security teams drowning in undiscovered external assets will find Assetnote Attack Surface Management Tool's hourly scanning and automated enrichment actually catches the forgotten domains and shadow IT that quarterly pen tests miss. The platform covers NIST ID.AM and ID.RA rigorously, with zero-day research and PoC exploits included rather than sold separately. Skip this if your org needs continuous monitoring of internal infrastructure or if you expect one tool to handle both external discovery and remediation workflow; Assetnote excels at finding and classifying what's out there, not orchestrating fixes across teams.
