Cybereason vs Horizon3.ai
Side-by-side comparison of AI visibility scores, market position, and capabilities
Cybereason is an AI-driven endpoint detection and response platform that correlates behavioral signals across endpoints to detect and visualize the full attack story.
About
Cybereason is a cybersecurity company headquartered in Boston, Massachusetts that provides AI-powered endpoint detection and response (EDR), extended detection and response (XDR), and managed detection and response (MDR) services to enterprises and government organizations worldwide. Founded in 2012 by veterans of the Israeli military's elite Unit 8200 intelligence division, Cybereason built its platform around a fundamentally different approach to threat detection: rather than detecting individual malicious events in isolation, the company's MalOp (Malicious Operation) engine correlates thousands of behavioral signals across all endpoints simultaneously to construct a complete, chronological attack story — showing security analysts exactly how a threat entered the environment, which systems were affected, what lateral movement occurred, and what the adversary's ultimate objective was. Cybereason has raised over $400 million from investors including SoftBank and Liberty Strategic Capital.
Horizon3.ai's NodeZero platform has executed 170,000+ autonomous pentests across 4,000 companies; reported 137% ARR growth in 1H 2025 with enterprise ARR up 485% YoY;
About
Horizon3.ai is a cybersecurity company founded in 2019 by former US National Security veterans and headquartered in San Francisco. Its flagship product, NodeZero, is an autonomous penetration testing platform that executes real-world attack techniques without agents or disruption — simulating what a sophisticated attacker would do across networks, Active Directory environments, cloud infrastructure, and containerized workloads. NodeZero autonomously discovers and chains vulnerabilities, exfiltrates credentials, and generates remediation guidance, replacing the need for infrequent and expensive manual pentests.
