An authoritative overview of the CISA KEV Catalog threat intelligence feed, covering its delivery mechanisms, publication schedule, and security architecture integration.

Technical Specifications

Overview & Operational Role

The CISA KEV Catalog stream delivers indicators and intelligence classified under Exploited Vulnerabilities. Within a Security Operations Center (SOC) or automated incident detection pipeline, this feed is designed to support real-time triage, automated blocklist compilation, or retrospective log correlation.

When ingested into SIEMs, SOAR playbooks, firewalls, or IDS/IPS engines, the feed enables security teams to identify threats matching known indicators using JSON API endpoints.

Integration & Ingestion Architecture

Integrating CISA KEV Catalog into your detection pipeline requires planning around ingestion rates and format parsers:

• Protocol Handling: Ensure downstream log collectors or ingestion scripts support JSON API parsing natively or via ETL transformation.
• Update Frequency: Data is published on a Periodic schedule. Configure polling jobs or webhook consumers to match this cadence without tripping rate limits.
• Licensing & Access: This stream operates under a Free/Open Source model. Review endpoint terms, quota headers, and authentication token requirements prior to production rollout.
