How they got in

Initial access via unpatched VPN appliance (CVE class: remote code execution on perimeter device). Lateral movement across flat hospital network enabled rapid propagation to all clinical systems within 36 hours. Credential harvesting preceded payload detonation.

Sentinel / Fortress / Command coverage

Sentinel 24/7 SOC would have flagged the VPN anomaly within minutes of initial access — abnormal authentication pattern from external IP
Sentinel Lateral movement detection: internal east-west traffic volume spike would trigger SIEM correlation rule within 2 hours
Fortress Vulnerability management would have flagged and patched the perimeter VPN CVE within 72 hours of public disclosure — months before this attack
Command vCISO quarterly review would have identified flat network topology as HIPAA-reportable gap; segmentation remediation recommended in prior cycle

Sentinel ($89/ep/mo) — 24/7 SOC + SIEM. Fortress ($109/ep/mo) — Sentinel + EDR management + vulnerability management. Command ($129/ep/mo) — Fortress + vCISO + compliance mapping + IR plan. See full tier comparison →
