Horizon3.ai Tech Stack

Autonomous pentesting platform for continuous attack-surface verification

Computer and Network Security San Francisco, CA 201–500 employees Founded 2019 Privately Held

Horizon3.ai builds an autonomous pentesting platform (NodeZero) that runs production-safe security assessments without agents or consultants. The stack reveals infrastructure maturity—Kubernetes, Terraform, Crossplane, ArgoCD—paired with sales infrastructure (Salesforce, Gong, Gainsight, LinkedIn Sales Navigator) that signals a sales-led motion. Hiring skews heavily toward sales (30 roles) over engineering (9), suggesting rapid customer acquisition alongside the transition from consulting-driven to product-driven pentesting delivery.

About Horizon3.ai

Horizon3.ai operates an autonomous pentesting and attack-surface management platform targeting mid-market and enterprise security teams. The NodeZero platform continuously identifies, prioritizes, and verifies fixes for exploitable weaknesses across internal, external, cloud, and hybrid environments. Founded in 2019 by former U.S. Special Operations cyber operators and security practitioners, the company addresses repeated pain points: alert fatigue from false positives, alert-driven rather than outcome-driven security tools, and the high cost and long lead times of external penetration testing services. The organization spans 201–500 employees, headquartered in San Francisco, and is actively hiring across the United States, Netherlands, Indonesia, Australia, Uganda, and Canada.
