- Detected and interrupted a live ransomware attack against the district mid-execution — identified indicators of compromise, mapped and contained lateral movement, halted the threat before encryption occurred, and led the post-incident executive and board-level briefing.
- Drove the resulting enterprise security program: scoped, procured, and deployed an EDR/MDR solution with 24/7 SOC coverage; defined MSSP escalation workflows, alert triage procedures, and incident response runbooks; applied NIST CSF and MS-ISAC guidance throughout.
- Administered Google Workspace (5,000+ accounts), Azure AD, Microsoft Intune MDM, FortiGate firewall, and Mitel telephony; managed vendor relationships and technology budget planning.
- Served as MS-ISAC member and CISA stakeholder — applied federal threat intelligence, KEV advisories, and Shields Up guidance operationally to harden district infrastructure and inform security investment decisions.
