VP & CISO
Catholic Health Long Island
We changed what cybersecurity is at Catholic Health. It was a control function. It is now a capability the business plans around. One governance model replaced many, allowing us to assess once and report across federal, state, and payer obligations. Detection and response moved to a 24-hour clock. We consolidated a fragmented identity environment, shortening clinician onboarding and removing access no one needed. Our independent security rating reached top-tier performance, and our insurers priced that improvement at renewal. The program now protects the four things every executive team cares about: patient safety, operational uptime, financial exposure, and institutional trust.
