Scanning & Searching Version 1.5.0 of Rumble Network Discovery is live with updates in two major areas; wider scanning, through improved protocol support, scan engine enhancements, and more comprehensive decoders; and deeper searching, with the addition of a dozen new search filters and other enhancements to the web console. Wider Scanning Whether you use the Rumble Agent or the Rumble Scanner, the scan engine improvements in v1.5.0 make discovery more reliable, predictable, and comprehensive.
Data transparancy is one of the key drivers of Rumble development. We do our best to ensure that any data gathered, transmitted, or downloaded is easy to view, import, export, and reprocess. Data generated by the Rumble Agent can be downloaded and reprocessed by the Rumble Scanner. Raw data from the Rumble Scanner can be imported into the Rumble Console. This data is consistently formatted and almost always backwards compatible between versions.

To leverage SNMP v3 credentials in a Rumble scan, set the following options in the Advanced Options section of the Scan Configuration screen. Depending on your environment, these settings may require some tweaking. The standard security levels of NoAuthNoPriv, AuthNoPriv, and AuthPriv map to these options as follows:
This Tuesday, Jonathan Looney, a researcher at Netflix, disclosed seven different ways to break common HTTP/2 protocol implementations, while an eighth issue was disclosed by Piotr Sikora of Google. These issues could be used to exhaust the resources of affected HTTP/2 implementations. Shortly after the HTTP/2 issues were disclosed, a Rumble user reached out asking if we could help identify HTTP/2 endpoints on their network. We are happy to announce that as of version 0.
Thanks to the wonderful user feedback from Beta 5, a handful of bug fixes and improvements have been deployed along with a new feature: Network Bridge Detection! The bridge report shows external networks in red, internal networks in green, and multihomed assets that bridge these networks in orange. Zooming in will show asset and subnet details, while clicking a node will take you to the asset page for bridge nodes and to a CIDR-based inventory search for network nodes.
