Cisco Umbrella Popularity List
Security teams building threat intelligence feeds on a shoestring budget should start with Cisco Umbrella Popularity List; it gives you real passive DNS signal from a global network without negotiating a contract. The list surfaces domains queried across millions of endpoints daily, which means you're working with actual traffic patterns rather than honeypot data. Skip this if you need enrichment, scoring, or integration with your existing SIEM; this is raw domain popularity rankings, nothing more.
Mid-market and enterprise SOC teams that need early visibility into adversary command-and-control infrastructure should prioritize IronNet IronRadar, since most threat feeds react to known C2 after it's operational, not before. The platform's collective defense model means you're detecting infrastructure weeks earlier than traditional feeds by pulling from a shared sensor network across participating organizations. Skip this if you're looking for a general-purpose threat intelligence platform; IronRadar is deliberately narrow,it trades breadth for speed on one specific attack vector.
