Critical Research Corporation

Rumble Network Discovery is a product of Critical Research Corporation. Our mission is to help our customers identify, manage, and monitor their networked IT assets as effectively as possible, without getting in their way. We do this by developing new techniques and software through applied research. We are based in sunny Austin, Texas.

Who We Are

HD Moore, our founder and CEO, has spent the last 20 years conducting security assessments, building security products, and pushing the status quo through research, with leadership roles at Digital Defense, BreakingPoint Systems, Rapid7, and Atredis Partners. HD founded Critical Research to address a long-standing need for better network discovery tools.

What We Make

Our first product, Rumble Network Discovery, provides ridiculously fast and comprehensive network discovery without the need for credentials or tap port access. Rumble was built from scratch for modern networks and works where most discovery products give up, enumerating MAC addresses, hostnames, and services across remote networks, within hardened environments, without special configuration.
