Has your organization established and implemented formal plans for managing software and service end-of-life, including maintenance support timelines and obsolescence procedures?

Software and services that reach end-of-life (EOL) without proper planning create significant security vulnerabilities when vendors stop providing security patches and updates. A formal EOL management plan ensures timely migration to supported alternatives, prevents security gaps, and maintains operational continuity when components become obsolete. This planning should include identification of all software assets, their lifecycle stages, and defined transition procedures. Evidence could include a documented EOL management policy, lifecycle tracking spreadsheets/tools showing EOL dates for key systems, migration planning documentation, or meeting minutes showing regular reviews of upcoming EOL software components.
