• Oversee data protection, encryption, and identity management initiatives across sites.
• Manage cybersecurity due diligence and oversight for vendors, suppliers, and partners.
• Collaborate with Procurement and Legal to integrate security requirements into contracts and service agreements.
• Promote cybersecurity awareness and accountability across all levels of the organization.
• Oversee employee training programs on phishing, safe system use, and industrial cyber-physical security.
• Engage with plant leadership and EHS (Environment, Health, and Safety) teams to align cyber and physical safety programs.
