Assetnote Attack Surface Management Tool
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.
Security teams responsible for internet-facing infrastructure need Shodan to find what attackers see before attackers do. The free tier gives you real-time visibility into your own exposed devices, services, and default credentials across millions of internet scans without licensing friction. Skip this if your organization lacks the operational discipline to act on what you find; Shodan surfaces problems faster than most teams can remediate them, which creates noise without a triage process in place.
