Case Study: IT Services Company achieves exploit-driven prioritization and broader coverage with Horizon3.ai's NodeZero

IT Services Company - Customer Case Study

IT Services Company engaged Horizon3.ai to validate the value of their outsourced MSSP pentest and vulnerability scanning. Concerned they were paying for incomplete or noisy assessments, the customer asked Horizon3.ai to run NodeZero, the vendor’s autonomous penetration testing platform, to compare coverage and exploitability against the MSSP’s manual pentest.

Horizon3.ai used NodeZero to run a full assessment, covering 3,644 hosts in 2.75 days versus the MSSP’s ~600 hosts and multi-week effort. NodeZero proved far more accurate and actionable — finding BlueKeep on 12 hosts (vs. 1), EternalBlue on 14 hosts (vs. 2), surfacing 14 file shares with over 2 million files (including keys), and gaining root access to three database servers — demonstrating broader coverage, faster results, and fewer false positives than the MSSP.
