Assetnote Attack Surface Management Tool vs Majestic Million: Side-by-Side Comparison (2026)

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.

Majestic Million

Competitive intelligence teams and threat researchers mapping attacker infrastructure will find Majestic Million's free access to the top one million websites ranked by referring subnet topology invaluable for understanding which domains carry outsized influence in the threat ecosystem. The dataset has been public since 2012 and powers reconnaissance workflows across security firms and bug bounty platforms. This is not a replacement for active scanning or vulnerability assessment; it's a passive reference layer for prioritizing which internet properties matter most when you're building your external attack surface inventory.
