runZero

What the company sells

runZero is a security company that sells the runZero Platform, which provides security visibility across IT, OT, IoT, cloud, mobile and remote assets.

runZero says that agents only see what they are installed on, and that scans relying on credentials leave blind spots when credentials change or fail. runZero describes its approach as high-fidelity fingerprinting for IT, OT and IoT assets with no agents or credentials required. The company says its platform combines safe active scanning, passive discovery, API integrations and advanced fingerprinting, and that it profiles each asset against nearly 1,000 attributes.

On the discovery side, runZero says its passive discovery provides always-on coverage for fragile OT environments where active scanning is not permitted. runZero also says its active scanning uses advanced fingerprinting to extract insights into operating systems, services, hardware and installed software.

runZero says it integrates with a wide variety of tools, enhancing network visibility, enriching asset data and uncovering control gaps. The integrations pages describe a CrowdStrike integration that syncs and enriches the asset inventory, and a Microsoft Active Directory integration that syncs data about assets, users and groups from a domain controller via LDAP. Where a tool has no integration, Platform and Community users can add asset data from custom sources with the custom integrations feature.

runZero 5.1 introduces AI workflows, including natural language searches, dashboard and report creation, autonomous discovery and AI-assisted custom integrations. runZero also describes a native Dragos integration that brings deep OT context directly into the runZero platform.

runZero offers a free version of the runZero Platform, which it calls ideal for home use and environments with fewer than 100 assets. The pricing page also describes an optional self-hosted console that requires a Platform license.

runZero was founded in 2018 by HD Moore, who is known as the creator of Metasploit. runZero was once called Rumble. Rumble raised a $15 million Series A round led by Decibel Partners, and rebranded to runZero in August 2022. runZero is now a Dragos company, joining Dragos along with NetRise. runZero is headquartered in Austin, Texas, and its team is 100% remote within the USA.

runZero describes a case study in which runZero became the foundation for exposure management across 343 North Carolina Public School Units.^{[1][4][6][7][8][9]}
