Questions & Answers

As answered by people managing DownDetector and runZero.

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.

What makes your product unique?

runZero's answer:

The runZero Platform is the only total attack surface and exposure 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.

    For network scanning / lite asset management I would recommend rumble.run. Source: over 4 years ago
  • Domotz vs Auvik
    Have you looked at https://rumble.run. Source: over 4 years ago
  • Guidance - Documentation
    I would start by using https://rumble.run and do recon of all the devices and services. That will give you a better understanding of what is there and what it does. You can do it by hand but this will scan whatever network subnets you give it. Source: almost 5 years ago
