Case Study: Shannon Medical Center achieves 90% reduction in vulnerabilities with ActZero

ActZero Helps Texas Hospital Reduce Security Vulnerabilities

Shannon Medical Center, a regional hospital in San Angelo serving roughly 300,000 people with over 3,750 employees and 350 providers across 26 locations, faced growing cybersecurity risk with a small IT team of about 25 and just one cybersecurity specialist. To shore up defenses as digital tools like iPads increased the attack surface, Shannon Medical Center engaged ActZero for additional security expertise and support.

ActZero deployed its full-stack cybersecurity solution (including ActZero MDR, Sixth Sense AI, experienced threat hunters, and a 24/7 SOC) to provide continuous monitoring, proactive hunting, auto-blocking, and high-fidelity detections integrated with Microsoft 365. Within three months, ActZero helped reduce vulnerabilities by 90%, cut false positives and alerts, enabled account-related responses in seconds, and gave the IT team measurable time savings and a markedly stronger security posture.
