About runZero

We're on a mission to create new solutions to solve persistent problems.

Who We Are

We're challenging the status quo to deliver better outcomes for our customers.

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 and exposures their current security stacks are unable to detect. Even those who invest in mature security 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 usher in the new era of exposure management.

2018 - 2020

runZero was founded as Rumble Network Discovery

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.

Analysts on runZero

Omdia Report: runZero offers an expanding portfolio in exposure management

Download Omdia's "On the Radar" report to read their assessment of runZero and get the analysts' take on our expanding exposure management capabilities.

“While runZero started out in the most complex side of ASM, namely the CAASM market, it is already expanding into EASM and broader exposure management use cases, which is a salutary development. Its CAASM background provides the most solid foundation for such a move, giving it valuable insights into a customer’s asset estate and making it a strong candidate for any ASM or exposure management project within an organization."

— Rik Turner, Senior Principal Analyst at Omdia

CECA evaluations confirm runZero's active scanning enhances ICS visibility without performance impact on SCADA

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.
