Rumble, Inc.

Rumble is a fast, easy, and accurate network and asset discovery platform that inventories IT and OT environments to provide a foundation for attack surface reduction and incident response programs.

Rumble brings together the best of IT, security and networking technology to deliver amazing network discovery and asset inventory capabilities for modern enterprises.

Rumble was founded in 2018 by HD Moore and Chris Kirsch. The company is headquartered in Austin, Texas.


Rumble is the maker of Rumble Network Discovery, an asset inventory in IT and OT environments. After gaining fast network visibility, Rumble’s customers use the SaaS platform to tag asset owners, identify risks, map network topology, accelerate incident response efforts, find old hardware, and manage IP space.


The Rumble Explorer scanner does not require credentials, agents, or SPAN ports to provide highly accurate fingerprinting. It helps security teams identify risks such as outdated and orphaned devices, rogue RDP ports, and public-private network bridges.


Rumble offers a free Starter Edition for networks with less than 256 assets. Today, over 11,000 users have the Rumble Starter Edition.


Rumble is backed by Decibel Partners, Jon Oberheide (co-founder and CTO, Duo Security), Andrew Peterson, Ash Devata, Chenxi Wang, Chris Nickerson, Christian Kanja, David Eckstein, and others. The company raised $15M in Series A round on Mar 15, 2022. This brings Rumble's total funding to $20M to date.
