Deteqtive
Passive DNS
Intelligence
Deteqtive is Spamhaus’s passive DNS investigation platform. Use fuzzy and exact search to surface phishing campaigns, brand infringement and malicious domains - pivot from a single indicator to the full picture in the UI, via API or directly using AI agents over MCP.
Pivot through DNS
Move effortlessly between domains and IP addresses to rapidly map related infrastructure.
Brand Protection
Surface typosquats and lookalike domains targeting your brand before they’re weaponized for an attack campaign.
API and Bulk Export
Query via REST API or stream results as NDJSON, designed to integrate with existing tooling, rather than replace it.
Built for AI Agents
Connect AI agents directly over MCP, so investigations happen inside your existing workflows.
Why Deteqtive?
Rely on Spamhaus passive DNS intelligence for phishing, brand abuse and threat work.
Patterns, not just Records
Fuzzy and exact matching, plus pattern surfacing, turns a single lookalike domain into visibility of the entire campaign behind it.
Threat-Focused Data
Our DNS corpus is enriched with malicious and abusive infrastructure - so relevant signals stand out from the noise.
Open & API First
The same data across UI, REST API, NDJSON bulk feeds, and over MCP for agents - built to integrate, not to lock-in.
