JPCERT/CC Security Alerts
JPCERT/CC is Japan’s national CERT and one of the oldest incident response teams in Asia. Its English security alerts flag vulnerabilities and attack campaigns relevant to Japanese organizations — often including exploitation observed in Japan before it is widely reported elsewhere. CSIRTS.com fetches the full alert body for every entry, not just the headline.
CSIRTS.com ingests JPCERT/CC Security Alerts 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 security alerts and incident reports. Also available via RSS, JSON API and the MCP server.
