Joseph Serrano

I am a security-focused systems administrator and data analyst with experience managing IT operations in healthcare environments. I combine system hardening, vulnerability management, and incident detection with data-driven analysis to improve security posture and operational outcomes.

At HealthProMed I led vulnerability assessments using Nessus and Nmap, implemented endpoint detection (Sophos Central), and automated detection and enrichment with PowerShell and Python scripts. I designed phishing simulations, deployed MFA across Azure/M365/Sophos, and produced compliance reports aligned with HIPAA and HITRUST.

I built analytics solutions—centralized SQL databases, PowerBI dashboards, Python-based log parsing, and frequency/event-correlation scripts—to surface trends and support executive briefings. I also supported EHR data analysis, statistical trend identification, and collaborated with vendors to drive system improvements.

I bring strong technical breadth across Active Directory, VMware, Azure, AWS, Exchange, and networking tools, paired with communication skills and a disciplined, team-oriented mindset. I seek roles where I can strengthen security, automate processes, and deliver measurable risk reduction.
