• Support internal compliance requirements and assist with any applicable regulatory or customer security assessments
• Maintain vulnerability management program including tracking, reporting, and remediation metrics
• Assist with vendor risk assessments and third-party security reviews

• OT / Industrial Environment
• Provide basic cybersecurity support for operational technology (OT) environments including conveyor automation and engineering lab systems
