Intelligence Sources
Configured feeds are reliability-weighted so SOC teams can see why a verdict was produced.
Active
New Threats (24h)
Indicators indexed in the last day. Continuous monitoring means you always query the latest intelligence.
Multiple
Source Evidence
Assessments show contributing sources so analysts can review agreement and conflicts.
Capabilities
What Powers the Platform
Every check fans out across hundreds of intelligence sources, correlates the evidence, and returns one explainable verdict — in a single API call.
AI-generated Analysis
LLM summaries turn raw enrichment into a threat narrative with recommended next steps, tailored to the indicator in front of you.
MITRE ATT&CK Mapping
IOCs map automatically to ATT&CK techniques from threat tags and findings — triage faster with structured threat models.
Monitoring & Alerts
Watch critical IPs and domains 24/7. Get notified the moment a watched asset turns suspicious or its threat status changes.
Bulk & Streaming Checks
Thousands of indicators per request over the bulk API, or progressive results streamed over SSE for long-running lookups.
Similarity Search
Fuzzy matching surfaces look-alike domains and related infrastructure, exposing coordinated campaigns behind a single IOC.
