Exposure management needs a reboot. Great research is the key to innovating new solutions.

Securing your total attack surface has never been more challenging. We believe that applied research is fundamental to building better security solutions to address both new problems and the persistent ones that dog security teams. By sharing our research, tools, and knowledge with our community, we can help each other proactively improve our defenses and raise the bar on attackers.

Divining Risk: Deciphering Signals From Vulnerability Scores

Vulnerability scores promise clarity, but too often just add to the noise.

We analyzed signals from over 270,000 CVEs to reveal what CVSS, EPSS, and SSVC actually tell us — and what they don’t.

BSidesSF: Charting the SSH Multiverse with HD Moore

The Secure Shell (SSH) is the most commonly exposed dedicated management protocol, second only to HTTP in terms of internet-wide exposure, and it’s had a rocky year. This presentation explores the multitude of SSH implementations, their specific weaknesses, and real-world exposures.

Keynote

NSEC: A Pirate's Guide to Snake Oil & Security

Watch as HD Moore takes you on a satirical voyage through the crowded world of vulnerability management. From clashing tribes to competing frameworks, HD examines how defenders can navigate vendor claims and hype to uncover what actually works.

Vulnerability management is broken: what's the fix?

HD Moore and Omdia analyst Rik Turner discuss why traditional vulnerability management is struggling in modern IT infrastructures, why CVEs don’t tell the full story, and why prioritization alone isn’t enough to close critical security gaps. They also explore how exposure management offers a fundamentally different approach that’s better suited for today’s evolving threat landscape.

Explorers, innovators, & experts

Meet the team behind our research.

We are a group of industry veterans with decades of experience in information security, who are committed to runZero’s foundational principle that applied research makes for better asset discovery, and that better asset discovery is the foundation of modern exposure management.

The goal of the runZero research team is to discover incredibly efficient ways to pinpoint at-risk devices and quickly get this information into the hands of our customers and community. We achieve this through both precise fingerprinting and fast outlier analysis across IT, OT, IoT, cloud, mobile, and remote environments.
