What we’re building

Know when a CVE in your stack becomes known-exploited.

AntiZeroday is a tool we are building to track exploited vulnerabilities for your stack: tell it what you run and get alerted when a matching CVE is added to CISA’s Known Exploited Vulnerabilities (KEV) catalog. It is in development.

AntiZeroday is in development and not yet available. The features below describe what we’re building for the first release.
