runZero Platform

21-Day Free Trial

Trusted by leading organizations.

To defend against anything, you have to see everything — and that’s exactly what runZero delivers

runZero is the only exposure management platform that provides complete visibility across your entire attack surface—both internal and external—without the need for agents, credentials, or appliances. Leveraging active scanning, passive discovery, and seamless integrations with advanced fingerprinting, runZero delivers the fastest and most comprehensive insights into your IT, OT, IoT, mobile, and cloud environments.

Make runZero your single source of truth for exposure management. Continuously uncover unseen assets, identify hidden risks, ensure compliance, and address critical vulnerabilities before they can be exploited.

Three Powerful Approaches

Our unique combination of discovery approaches delivers the best depth & accuracy.

Unrivaled Active Scanning- Safe for IT, OT, and IoT
Our proprietary active scanning technology sets the gold standard—uncovering everything, including unknown and unmanageable devices, with an unparalleled depth of data. Extract rich insights into OSs, services, hardware, and installed software through advanced fingerprinting—proven safe for even the most sensitive OT and IoT environments.

Passive Discovery-Fast, Accurate, Always-on
Our groundbreaking passive discovery approach outperforms traditional methods—delivering greater efficiency, faster deployment, and instant, visible results. Always on and designed for fragile OT environments where active scanning isn’t an option, it ensures continuous coverage, deep fingerprinting, and unmatched data accuracy.

Seamless Integrations – Unified Data and Insights
Our pre-built API integrations and SDK empower you to connect with leading cloud providers, EDRs, MDMs, and vulnerability scanners—creating a single source of truth across complex environments. Effortlessly correlate data and enrich asset details, while robust egress integrations eliminate silos and integrate insights into existing workflows.

Don't Take Our Word for It

“runZero has been an excellent company to work with. As we say, you can't secure what you can't see, and I needed to know what was out there in a highly distributed environment that has 22 business lines, each with a high degree of disparity in their technology needs. From cameras, drones, ICS, SCADA, radios, non-traditional IoT devices, and traditional IT infrastructure. The runZero team has been highly engaged and dedicated to our success, working extensively with our SecOps to deploy and configure Explorers and collaborating on OT and IoT fingerprints. We've matured significantly in our asset inventory and event response because of this partnership and I think I'd have a mutiny on my hands if I ever took it away!”

“We finally have confidence in what assets we have across multiple, disjointed networks across multiple clouds and datacenters. runZero is what lets us verify or call B.S. on what engineering teams tell infosec. I have repeatedly heard "CrowdStrike is deployed on all of our servers" from an engineer only to go back to runZero and show them exactly which ones don't have it.”
