Life at Horizon3 AI

Our story… We are the fusion of former US Special Operations cyber operators, startup engineers, and frustrated cybersecurity practitioners. We see the world for what it is - bloated security tools, alert fatigue, reports filled with false positives, "checkbox" security culture, and consultants trying to pitch their "expertise". Our approach: We use the "Attacker's Perspective" to cut through the noise and help you find & fix security problems that matter. We deliver that attacker's perspective by running continuous, automated pen-test & red team operations, building “cyber terrain maps”, and running analytics to identify angles of attack. We deliver these capabilities as a true SaaS – no consultants, no professional services, and no “cheating” with agents or up-front configurations
