Famed security expert HD Moore’s latest project — an IT and OT asset-discovery platform that attempts to address the-age-old challenge of finding and fingerprinting devices that reside on an organization’s network and their status — just landed $5 million in venture capital funding from some major players in network and security technologies.

The VC round for Moore’s Rumble startup was led by Cisco-backed Decibel Partners, via Jon Sakoda and Dan Nguyen-Huu. Other investors include security entrepreneurs Jon Oberheide, co-founder and CTO of Duo Security; Demisto (now part of Palo Alto Networks) founders Slavik Markovich and Rishi Bhargava; Phantom Cyber (now part of Splunk) founder and CEO Oliver Friedrichs; Thinkst Canary founder Haroon Meer; and StoneMill Ventures founder Michael Sutton.
