Network and asset discovery provider Rumble this week announced that it has raised $5 million in VC funding. The round was led by Jon Sakoda and Dan Nguyen-Huu at Cisco-backed Decibel Partners.
The round also saw participation from Duo Security co-founder and CTO Jon Oberheide, Demisto (acquired by Palo Alto Networks) founders Slavik Markovich and Rishi Bhargava, Phantom Cyber (acquired by Splunk) founder and CEO Oliver Friedrichs, Thinkst Canary founder Haroon Meer, and StoneMill Ventures founder Michael Sutton.
Founded by H.D. Moore, who is best known for creating Metasploit and who also started Rapid7’s Project Sonar, Rumble officially launched in October 2019, after a six-month beta period. At the end of 2020, the company had over 100 paying customers.
The Rumble platform has been designed to inventory IT and OT environments to help with attack surface reduction and incident response.
Rumble’s Explorer scanner was designed to identify outdated and orphaned devices and rogue RDP ports, as well as for the discovery of public-private network bridges, thus increasing security teams’ visibility into enterprise environments.
The new funds, Rumble says, will help it expand the enterprise capabilities of its platform and also accelerate its go-to-market engine.
The funding round was accompanied by Rumble’s 2.0 release, which features ServiceNow ITOM CMDB integration, new discovery modes to identify active subnets and hosts, automated monitoring, expanded API capabilities, and more.
“Most security teams have been trying to get asset inventory data from solutions that weren’t designed for it, such as vulnerability scanners and EDR agents. These solutions weren’t created with that goal in mind, so the data is often spotty, either because it doesn’t properly identify the device or misses it altogether,” HD Moore commented.
