Case Study: Large Regional Hospital achieves 95% reduction in false positives and improved security visibility with ActZero

ActZero helps southeast U.S. medical center focus its cybersecurity efforts

Large Regional Hospital, a mid-sized medical center in the U.S. southeast with about 3,500 staff and over 8,500 endpoints, faced growing cyber threats while operating with only two dedicated security staff and a minimal budget. Their previous MSSP-managed SIEM failed penetration tests, generated overwhelming false alerts, and provided poor visibility and remediation. The organization engaged ActZero and its MDR (managed detection and response) service to replace the failing solution and strengthen foundational security.

ActZero deployed a comprehensive endpoint, network, and cloud MDR stack with 24/7 support, a customer portal, Technical Account Managers, and vCISO guidance, completing onboarding in 10 days. Initial scans found nearly 7,500 vulnerable assets; ActZero prioritized patching, MFA, and admin controls, and delivered ~95% reduction in false positives, eliminated alert fatigue, and produced clearer risk dashboards—yielding $75K+ annual net savings from removing the prior managed-SIEM and significantly improved visibility and response.
