Microsoft Security Response Center

The Microsoft Security Response Center (MSRC) publishes CVE-level security update information for Windows, Office, Azure, Exchange and the rest of the Microsoft portfolio, including whether a vulnerability was publicly disclosed or exploited before the fix shipped.

CSIRTS.com ingests Microsoft Security Response Center 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 CVE-level security update guide entries. Also available via RSS, JSON API and the MCP server.
