• Provide risk-based recommendations to stakeholders to support remediation prioritization decisions

Reporting & Communication

• Prepare periodic status reports/dashboards on vulnerability management, risk register status, and outstanding risk acceptances for leadership review
• Communicate effectively with technical SMEs, business stakeholders, and management across varying levels of technical understanding
