Donald Cowin

I've led cybersecurity strategy, security operations, and regulator-mandated breach remediation for Wachter Cyber Defense and Booz Allen Hamilton, supporting financial services and critical infrastructure clients. My work has reduced audit findings by up to 70% and strengthened compliance readiness through continuous risk governance.

I've modernized cloud and hybrid environments with Zero Trust controls, migrated 300+ Exchange servers to O365, and built incident-response capabilities using SIEM, Microsoft Defender, CrowdStrike, threat hunting, and risk-based vulnerability management. I translate NIST CSF, ISO 27001, SOC 2, PCI DSS, HIPAA, and FedRAMP requirements into actionable controls, evidence standards, and executive risk reporting.
