runZero, Inc. builds an exposure management platform focused on cyber asset attack surface management, providing complete security visibility across IT, OT, IoT, cloud, mobile, and remote assets.[2][3][4] It serves security teams at leading global organizations, solving the critical problem of discovering unknown, unmanaged, and unmanageable devices without agents, credentials, or appliances—using proprietary active scanning, passive discovery, and API integrations to uncover hidden risks and reduce cyber exposure quickly.[1][3][5][6] The platform offers a free Community Edition for small environments, seamless tool integrations, and has earned validation as a leading Continuous Threat Exposure Management (CTEM) solution for complex setups, with case studies showing customers like York University discovering 2.5x more assets and accelerating M&A integrations.[2][3][5]
Growth momentum is strong, evidenced by trust from global enterprises, positive testimonials, analyst reports from Info-Tech Research Group praising its agentless approach and rapid threat detection, and upcoming events like a January 2026 webcast on M&A use cases with TeamSystem.[2][3]
runZero was founded in 2018 by HD Moore, the renowned creator of Metasploit, a foundational penetration testing framework.[1] Previously known as Rumble, the company emerged from Moore's experience as a security researcher and penetration tester, where he developed benign techniques to extract information leaks from networks and build device profiles without credentials.[1][2] This applied research evolved into a modern active discovery solution aimed at identifying *everything* on a network, addressing gaps in traditional tools and leading to the launch of runZero as a comprehensive asset inventory and visibility platform.[1]
Early traction built on Moore's credibility in cybersecurity, humanizing the company as a practitioner-led innovator transitioning security research into enterprise-grade tools.[1][2]
runZero rides the exploding demand for cyber asset attack surface management (CAASM) and Continuous Threat Exposure Management (CTEM), amid rising threats to hybrid environments with proliferating IT/OT/IoT/cloud assets.[2][3][5] Timing is ideal as regulations and breaches (e.g., Log4j-like incidents) push organizations toward instant visibility and agentless tools, countering market forces like shadow IT, remote work, and M&A complexities that blind traditional scanners.[3][6][7]
It influences the ecosystem by empowering security teams with actionable data for prioritization, integrations that bridge tools, and research-driven innovations from Metasploit roots—setting a standard for comprehensive, non-intrusive discovery in a fragmented visibility market.[1][2][7]
runZero is poised for accelerated adoption as CAASM/CTEM matures into must-have infrastructure, with expansions in passive discovery for OT and M&A use cases signaling deeper enterprise penetration.[2][3][5] Trends like AI-driven threats, zero-trust mandates, and edge computing will amplify demand for its agentless, full-spectrum approach, potentially evolving its influence through partnerships, global scaling, and free-tier virality to capture SMBs and consultants.[2][5][7]
Tying back to its practitioner origins, runZero exemplifies how security expertise turns network blind spots into defensible strengths—watch for leadership in exposure management as asset complexity surges.[1][3]
runZero, Inc has raised $20.0M across 2 funding rounds. Most recently, it raised $15.0M Series A in March 2022.
