Multi-Site Hospital Network

Full Case Study

A ransomware strain had encrypted three servers at a satellite facility before being caught by a legacy AV product — but the network's CISO knew they had narrowly avoided a catastrophe. The board mandated a full security overhaul and HIPAA compliance certification within 90 days.

Assessment Phase

Pulsosec's team conducted a two-week network penetration test across all 14 facilities and a remote workforce of 3,800 users. The vulnerability scan surfaced 2,300 distinct findings: unpatched Windows servers, default credentials on medical devices, unencrypted ePHI on shared drives, and no network segmentation between clinical and administrative systems.

Remediation

We delivered a prioritised remediation roadmap tiered by risk. Critical findings — including 47 directly exploitable remote code execution vulnerabilities — were patched within the first two weeks. Network segmentation was implemented to isolate clinical IoT devices. Endpoint detection was rolled out across all facilities.

Managed SOC Deployment

Following remediation, Pulsosec deployed our Managed SOC across all 14 sites. Our team integrated with the hospital network's existing Splunk instance, built custom detection rules for healthcare-specific threats (including HL7 protocol anomalies), and established a dedicated escalation path to the CISO.

HIPAA Certification

With technical controls in place, our GRC team completed the HIPAA Security Rule documentation package. The network passed its independent HIPAA audit with zero major findings — the first time in the organisation's history.
