Case Study: National Healthcare Staffing Organization achieves continuous internal pentesting and rapid remediation with Horizon3.ai’s NodeZero

Healthcare Staffing Organization Puts Cybersecurity Best Practices in Place with NodeZero

The National Healthcare Staffing Organization, a publicly traded company managing roughly 900–1,200 hosts and a growing remote workforce, faced challenges with aging internal software, undocumented or overlooked machines, and difficulty convincing the C‑suite to prioritize security. To address these internal risks, they turned to Horizon3.ai’s NodeZero to get an attacker’s perspective and pinpoint real, actionable threats rather than generic compliance findings.

Horizon3.ai’s NodeZero delivered an internally focused automated pentest that chained attacks to expose true risk—obtaining domain admin in 17 minutes via an overlooked machine that shared a password—and helped the organization move from annual testing to monthly scans with mid‑month retests. NodeZero also improved measurable defenses: it validated endpoint protection, cut MSSP notification time from four hours to 15 minutes, surfaced misconfigurations and false positives, and made remediation progress demonstrable; remaining gaps were primarily due to staffing, not detection.
