Rumble provides an active network discovery and asset inventory platform that identifies machines, unmanaged devices, and software without credentials using modern scanning and fingerprinting research. The product includes RFC1918 coverage reporting, IPv6 discovery, asset route pathing, integrations with MDM/EDR/cloud providers, and a self‑hosted Enterprise option. Rumble offers a free Starter Edition for networks under 256 assets and reports over 11,000 users on that edition. The company says that in 2021 it grew its user base 3x, customer base 4x, and ARR 5x, and closed a historic booking for 1 million assets. Since the Rumble 2.0 release it has expanded scanning, fingerprinting, reporting, and integration capabilities and continues to release product updates regularly. Rumble plans to use the new funding to ramp up hiring across go‑to‑market and engineering to accelerate technology and customer reach. Rumble provides a fast, easy, and accurate network and asset discovery platform (Rumble Network Discovery) that inventories IT and OT environments to support attack-surface reduction and incident response. Its Rumble Explorer scanner fingerprints devices without credentials, agents, or SPAN ports and identifies managed and unmanaged devices, outdated/orphaned hardware, rogue RDP ports, and public-private network bridges. The company offers a multi-tenant SaaS console, a self-host option for VPC or local networks, and a command-line scanner for air-gapped environments. The recent 2.0 release added ServiceNow ITOM CMDB integration, faster subnet discovery modes, an automated Rules Engine, and expanded API capabilities. Rumble plans to use the new funding to expand enterprise capabilities and broaden its go-to-market while growing go-to-market and engineering teams. The company was cash-flow positive in 2020, finished that year with more than 100 paying customers, has customers in over 20 countries, and its free Starter Edition is used by over 4,000 organizations.
