The Cisco Product Security Incident Response Team (PSIRT) publishes advisories for Cisco’s networking, security and collaboration products — IOS, IOS XE, ASA, Firepower, Catalyst and more. Because Cisco gear sits at the network edge, PSIRT advisories are recurring entries in the CISA KEV catalog.

CSIRTS.com ingests Cisco Security Advisories every 3 hours, normalizes each advisory into a common schema and cross-references every CVE against the CISA KEV catalog and public exploit datasets. Publishes product security advisories. Also available via RSS, JSON API and the MCP server.
