CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams filtering high-volume email and web traffic will see immediate ROI from SecurityZones SURBL BV because its feeds update every 1-2 minutes, catching newly registered phishing and botnet domains faster than most competitors can refresh. The FRESH feed specifically targets domains less than 72 hours old, where traditional blocklists have gaps, and native DNS RPZ and SIEM integrations mean you're not bolting on a separate lookup layer. Skip this if you need post-breach forensics or incident response context; SURBL BV is built for continuous monitoring at the gateway, not for characterizing compromises after they've landed.
Security teams running lean threat intel operations on a budget should use URLhaus for its real-time malicious URL feed, which gets indexed within hours of submission and covers malware distribution chains that commercial feeds often miss. The project processes thousands of URLs daily across a public API with no authentication requirement, making it trivial to integrate into existing detection workflows. Skip this if you need attribution intelligence, takedown coordination, or historical context on threat actors; URLhaus is a feeds library, not an investigative platform.
