The Missing Calendar Event: Making EOL Dates Actionable Security Deadlines

End-of-life dates are critical security milestones—once passed, every new vulnerability becomes permanently unfixed and publicly weaponized with no vendor remediation available. endoflife.ai solves the persistent oversight by embedding EOL dates directly into user calendars with smart reminders at 90, 30, and 7 days before expiration, converting reactive emergency responses into planned migrations. This lead time functions as a security control mechanism that reduces incident cost and aligns with CISA's positioning of unsupported software as a material national security risk.
