• Protect proprietary code, customer and network data, and personal information through data loss prevention, tenant and data isolation, least privilege, and insider-risk controls.
• Assess third-party AI and SaaS services for data retention, model training, privacy, copyright, and security risk before approval and throughout the vendor lifecycle.

4. Security Operations, Incident Response and Vendor Oversight

• Lead security monitoring, detection, triage, and response across cloud, identity, networks, endpoints, servers, and SaaS environments.
• Maintain and test incident-response, ransomware, and AI-related playbooks, including escalation paths, executive communications, and post-incident reviews.
• Manage SOC performance, including log coverage, alert quality, investigation standards, and service-level commitments.
• Oversee third-party security risk, audits, customer security questionnaires, cyber-insurance requirements, remediation plans, and the cybersecurity budget.
