• Deep experience across multiple domains:
• Endpoint Security (EDR, application control)
• SIEM platforms (Splunk, Sentinel, Elastic)
• Vulnerability management tools (Nessus, Qualys, Rapid7)
• Network security (Firewalls, IDS/IPS)
• Data protection and email/web security tools
• Experience implementing policy-driven and risk-based security controls
• Knowledge of cloud security and modern enterprise architectures

• Strong understanding of:
• Risk assessments and threat modelling
