• Contribute to threat assessments and support proactive threat hunting activities
• Help ensure alignment with standards such as General Data Protection Regulation, Payment Card Industry Data Security Standard, Network and Information Systems Regulations, and International Organisation for Standardisation 27001
• Monitor vulnerability management tools and processes, identifying ways to improve effectiveness and reduce risk
