Overview

Its Agentic Defined Networking platform combines a global private backbone, peer-to-peer encrypted communications, private naming and certificate infrastructure, DNS-level threat protection and APIs that allow AI agents to configure network boundaries. The product entered open beta alongside a $38 million Series A in October 2026.

Competitive landscape
Edge: doxx.net controls a vertically integrated networking stack—including backbone, naming, certificate authority and bare-metal infrastructure—rather than layering an agent feature onto a conventional VPN or cloud networking service.
The platform sits between consumer privacy tools, enterprise zero-trust networking and agent-security products. Its central challenge is turning architectural control into trusted, auditable security outcomes while achieving enough network reach and distribution to compete with established connectivity providers.
