• Perform penetration testing across networks, applications and infrastructure.
• Conduct adversary emulation exercises using threat intelligence and attacker methodologies.
• Identify vulnerabilities, attack paths and security weaknesses.
• Assess the effectiveness of existing security controls and detection capabilities.
• Produce actionable recommendations that improve cyber resilience.
• Work closely with Security Operations Centre (SOC) teams and Security Assurance specialists.
