• Track end-of-life (EOL) and compliance statuses across discovered assets to mitigate audit risks.
• Collaborate with SAM Analysts and Procurement teams for proactive lifecycle tracking and renewal notifications.
• Provide audit-ready asset intelligence by reconciling discovered data with compliance requirements and CMS operational policies.
