CSIS PhishDB vs Netcraft Domain Protection: Side-by-Side Comparison (2026)

CSIS PhishDB

Mid-market and enterprise security teams responsible for brand protection will get the most from CSIS PhishDB because its automated takedown system actually removes phishing sites instead of just flagging them, cutting response time from days to hours through direct ISP partnerships. The platform covers the full detection-to-response lifecycle across NIST's ID.RA, DE.CM, DE.AE, and RS.MA functions, with 24/7 monitoring that feeds results into Google Safe Browsing and APWG databases for broader threat distribution. Skip this if you need phishing defense integrated into a broader security awareness or endpoint platform; PhishDB is single-purpose and that's intentional.

Netcraft Domain Protection

Brand teams and security ops at mid-market companies will get immediate value from Netcraft Domain Protection because it catches lookalike domains faster than manual monitoring, using OCR and fuzzy matching to spot impersonation attempts that typosquatting alone misses. The tool monitors across multiple sources,CT logs, DNS, zone files, abuse reports,and automates takedown submissions, which cuts response time from days to hours. Skip this if your organization needs full account takeover protection or assumes your domain registrar will catch these threats; Netcraft is deliberately focused on detection and disruption, not remediation of compromised credentials downstream.
