This regional healthcare system faced a perfect storm of security challenges common in healthcare:
After evaluating multiple vendors, the healthcare system chose Vigilense AI for several key reasons:
PHI-containing logs could stay in their existing on-premise data lake. No data needed to leave their environment.
Not just alerting, but actual autonomous investigation and response. The promise of meaningful workload reduction.
Deploy-first, pay-later model meant they could prove value before any financial commitment.
| Metric | Before | After | Change |
|---|---|---|---|
| Daily Alerts Requiring Human Review | 15,000 | 150 | -99% |
| Mean Time to Investigate | 45 min | 4 min | -91% |
| Mean Time to Respond | 4 hours | 12 min | -95% |
| False Positive Rate | 85% | 8% | -91% |
| Analyst Capacity for Proactive Work | 5% | 70% | +1300% |
Challenge: Detecting unauthorized access to patient records across 200+ clinics.
Solution: AI correlates EHR access logs with work schedules, patient assignments, and behavioral baselines. Anomalous access patterns are automatically investigated and escalated.
Result: 15 insider threat cases identified in first 90 days that would have gone undetected.
Challenge: Thousands of IoMT devices with limited security controls.
Solution: Behavioral analysis of medical device network traffic. Automatic isolation of compromised devices without disrupting patient care.
Result: Contained a medical imaging system compromise within 3 minutes, preventing lateral movement.
Challenge: Healthcare is the #1 target for ransomware.
Solution: AI detects early indicators of ransomware (reconnaissance, credential access, lateral movement) and automatically contains threats before encryption begins.
Result: Blocked 3 ransomware attempts in first 6 months with zero patient care impact.
"We went from drowning in alerts to actually being proactive about security. Our analysts used to spend all day triaging false positives. Now they're doing threat hunting and security architecture work. The transformation has been remarkable and we did it while strengthening our HIPAA compliance posture."
