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.

HD Moore, the creator of Metasploit, envisions a modern active discovery solution that could find and identify everything on a network without credentials — and with that Rumble Network Discovery is founded.
In March 2019, the beta version of Rumble Network Discovery is launched. In April 2020, Rumble Starter Edition becomes available as a free tier, gaining traction and interest among consultants, home users, small businesses, bug bounty hunters, and researchers.
Rumble raises $5 million in VC funding led by Jon Sakoda and Dan Nguyen-Huu at Decibel Partners, a global venture capital firm backed by Cisco. Additional investors include well-known cybersecurity innovators and trailblazers. Rumble invests the funds to expand enterprise capabilities and broaden go-to-market reach.
Decibel Partners leads a $15 million Series A funding round. In August 2022, Rumble rebrands to runZero, increases the number of integrations to the Platform, and expands use cases to address additional security challenges.
The runZero Platform is launched, making it the only cyber asset attack surface management solution (CAASM) that unifies proprietary active scanning, native passive discovery, and API integrations to provide customers with the most complete, in-depth security visibility possible, empowering them to mitigate exposures quickly and reduce compliance risk.

The National Renewable Energy Laboratory (NREL)'s Clean Energy Cybersecurity Accelerator™ (CECA) program performed an evaluation of the runZero Platform that accurately identified and inventoried all OT and IT IP-addressable assets through proprietary active scanning and passive traffic sampling in the test environment.
The CECA evaluations confirmed the ability of runZero’s active scanning methods to improve visibility with no impact on the performance of the Industry Control Systems (ICS) or ongoing supervisory control and data acquisition (SCADA) processes and communications.
We're looking for bright minds and passionate souls who want to write the next chapter in exposure management.
