   Oct 2023 — Present · Manassas, VA, US

   As a Senior Cybersecurity Engineer at OnDefend, I lead enterprise-wide initiatives focused on enhancing data protection, regulatory compliance, threat detection, and cloud security. I have successfully implemented Microsoft Purview across endpoints, email, and cloud platforms—designing DLP policies, insider risk rules, and sensitivity labels that led to a 30% reduction in data loss incidents. I conduct continuous threat hunting and incident analysis using ArcSight SIEM, developing real-time correlation rules and compliance reports. My role includes deploying endpoint and email DLP tools to prevent unauthorized transmission of sensitive data, integrating DLP solutions with Secure Web Gateways (SWGs), CASB platforms, and Microsoft Defender for comprehensive protection.I led the implementation of Illumio Core micro-segmentation to secure data center migration, reducing lateral movement risk. I routinely perform risk assessments and apply mitigation strategies that have decreased the organization’s risk profile by 40%. My responsibilities also include architecting secure cloud environments using Azure, AWS, and GCP—focusing on encryption, IAM, and network security—while ensuring ongoing compliance with industry regulations such as PCI DSS, GDPR, HIPAA, and SOC 2. I’ve driven multiple PCI DSS audits, facilitated cross-departmental collaboration, and developed staff training programs to strengthen compliance awareness. Additionally, I use Power BI and audit log analytics to generate reports that support long-term strategic planning and governance enforcement. My efforts consistently align technical controls with organizational security goals to protect systems, networks, and applications.
