Key Outcomes
The Challenge
A five-person security team protecting 12 hospitals and 18,400 endpoints was drowning in alert volume and facing HIPAA compliance pressure following ransomware attacks at peer institutions.
The Solution
Alaris gave the team enterprise-grade autonomous triage, investigation, and response capabilities, dramatically reducing noise, closing compliance gaps, and allowing the team to focus on genuine threats.
Regional healthcare systems occupy a uniquely difficult position in the security landscape. They face the same threat environment as large enterprise organizations, healthcare is one of the most-targeted industries for ransomware and data theft, but with a fraction of the security resources. Two peer institutions in the same region had experienced ransomware attacks in the preceding 18 months. One had paid a $4.2M ransom. The other had suffered 11 days of system downtime affecting patient care. The CISO at this client knew they were next in line. They had five security analysts, 18,400 managed endpoints, and a regulatory environment that was about to get significantly more demanding.
The Challenge: Five Analysts, 12 Hospitals, Ransomware Season
Healthcare organizations are among the most targeted by ransomware groups because the combination of sensitive patient data and operational technology that directly affects patient care creates maximum leverage for extortion. The client understood this acutely, they had watched two peer institutions suffer attacks and had conducted detailed post-mortems on both.
The Alert Volume Problem
Before Alaris deployment, the team was receiving an average of 4,200 security alerts per day across their SIEM, EDR, and email security tools. With five analysts, meaningful investigation capacity was approximately 300 alerts per day. The other 3,900 were triaged by priority and most were dismissed without investigation.
The team's CISO estimated that in the six months before Alaris deployment, the team was dismissing approximately 250,000 uninvestigated alerts. Their primary concern: what was hiding in those 250,000 alerts?
The Compliance Pressure
HIPAA's Security Rule requires covered entities to implement reasonable and appropriate safeguards for electronic protected health information. The HHS Office for Civil Rights had recently concluded settlements with two healthcare organizations for inadequate security monitoring, settlements of $3.1M and $5.4M respectively. The client's legal team had flagged their current monitoring posture as a significant compliance liability.
Additionally, their cyber insurance renewal was coming up with a new requirement: demonstrate 24/7 security monitoring with documented response procedures. Their current model, five analysts working business hours with limited on-call coverage, did not meet this requirement.
- 5 security analysts covering 18,400 endpoints across 12 facilities
- No after-hours monitoring coverage except on-call escalation
- 4,200 average daily alerts with 93% dismissal rate
- HIPAA compliance posture rated 'at risk' by external auditors
- Cyber insurance renewal requiring 24/7 monitoring documentation
The Deployment: Healthcare-Specific Considerations
Deploying AI-native security in a healthcare environment requires specific attention to regulatory requirements, clinical workflow sensitivity, and the presence of medical devices and OT systems that can't tolerate endpoint agent overhead.
Clinical Workflow Protection
The single most important constraint in a healthcare deployment is ensuring that security response actions never interrupt patient care. The team worked with Alaris to implement a clinical system protection policy: any device tagged as clinical (patient monitors, infusion pumps, imaging systems, nurse station terminals) required human approval before any automated response action could be executed, regardless of alert severity.
For clinical devices that couldn't accept endpoint agents, Alaris used network-based behavioral monitoring to provide equivalent visibility without agent overhead, a critical capability for legacy medical devices running Windows XP and Windows 7 that couldn't be updated without FDA recertification.
HIPAA Compliance Integration
Alaris's audit and logging capabilities were configured to generate HIPAA Security Rule documentation automatically: access logs for ePHI systems, anomalous access detection with automated investigation, and periodic security reviews mapped to required administrative safeguard documentation.
Completed integration with Epic EHR security events, Cisco network infrastructure, Microsoft 365, and endpoint EDR. Discovered 340 previously unknown devices connected to the network, including 12 clinical IoT devices with no security monitoring.
Classified all 18,400 endpoints by clinical criticality. Deployed lightweight network monitoring for 847 clinical devices that couldn't accept agents. Built custom response policies for clinical environment.
Enabled full autonomous triage for non-clinical assets. Alert volume reaching analysts dropped from 4,200/day to 180/day. Team conducted initial threat hunt using freed capacity.
Deployed automated response workflows for 14 common attack scenarios. First successful automated containment: credential stuffing attack on employee VPN contained in 8 minutes with no data access.
HIPAA Security Rule documentation generation automated. Cyber insurance renewal completed with 24/7 monitoring documentation. First full compliance audit under Alaris: zero findings.
Results: 18 Months of Healthcare-Grade Security
In the 18 months since full deployment, the client has experienced zero ransomware incidents and zero reportable data breaches. Both peer institutions that suffered attacks before the client's deployment have since experienced additional security incidents. The security operations posture at the client has continued to improve quarter over quarter.
The Discovery: What Was in Those Dismissed Alerts
One of the most important findings from the deployment wasn't about attacks that happened, it was about attacks that were already underway when Alaris was deployed. Within 72 hours of initial deployment, Alaris identified active command-and-control communication from four workstations that had been compromised before the deployment began. Three of the four compromise events had generated alerts in the team's existing tools, alerts that had been dismissed as potential false positives due to alert fatigue.
The four compromised workstations were contained and remediated within 4 hours of Alaris deployment. Post-incident analysis determined the attacker had maintained persistent access for between 23 and 47 days before detection. No ePHI was accessed; the attacker appeared to be in a reconnaissance phase.
Cyber Insurance and Compliance Outcomes
The cyber insurance renewal was completed with full 24/7 monitoring documentation, resulting in a 22% premium reduction compared to the previous year's policy, partially offsetting the platform cost. The HIPAA compliance audit completed six months after deployment was the first in the organization's history to receive zero findings from external auditors.
Analyst Experience: From Overwhelmed to Effective
Security analyst experience in healthcare has historically been among the worst in the industry, high alert volumes, high stakes, difficult environment constraints, and chronic understaffing. The client's five analysts provide an informative case study in what changes when the alert burden is lifted.
Six months into deployment, all five analysts reported significantly higher job satisfaction in internal surveys. Two analysts who had been planning to leave the organization both chose to stay. The team launched a structured security awareness program for clinical staff, something they had never had bandwidth to do, which has since reduced phishing-related security events by 41%.
The CISO promoted the most senior analyst to a new role: Threat Intelligence and Hunting Lead, a position that hadn't existed before and wouldn't have been sustainable without the capacity freed up by Alaris. In the first year of that role, the new TI Lead identified and reported three threat actors actively targeting regional healthcare systems to CISA and the HHS Healthcare Cybersecurity Task Force.
