Questions and Answers

As answered by people managing runZero and Nmap.

What makes your product unique?

runZero's answer

The runZero Platform is the only cyber asset attack surface management solution that combines powerful proprietary active scanning, native passive discovery, and API integrations. Unifying these discovery approaches makes our platform unique in its ability to discover and provide accurate, detailed fingerprinting for all IT, OT, and IoT devices across on-prem, cloud, and remote environments.

What's the story behind your product?

runZero's answer

runZero was founded in 2018 by HD Moore, well known in the industry as the creator of Metasploit. Over the last 25 years, HD has led penetration testing teams, helped build three successful security products, and pushed the boundaries of security research.

Throughout HD's storied career, one persistent fact stood out: organizations that care about security are still frequently compromised through assets they don’t know about. Even those who invest in mature security and IT programs still struggle to achieve full visibility into increasingly dynamic environments that endure constant change in assets, networks, and clouds. HD founded runZero to solve this problem and lay the foundation for the next generation of exposure management.
