Risk Reporting: Configure automated reporting of compliance data to continuous monitoring systems and risk-scoring repositories.
Security Integration & Engineering
Tool Orchestration: Integrate Trellix and ACAS with tools such as Splunk, XSOAR, and ServiceNow to automate workflows and enhance incident response.

Strategic Oversight: Lead the maintenance and scalability of test, development, and operational environments, collaborating with Network and DevSecOps teams to enhance resilience.
Multi-Tier Support: Deliver Tier 1–3 maintenance and incident response for the full cybersecurity portfolio (ACAS, Trellix, Splunk, XSOAR).
