doxx.net, a private networking platform founded by Prolexic creator Barrett Lyon, has secured $38m in Series A funding and opened up its Agentic Defined Networking (ADN) platform to the public in beta.
Andreessen Horowitz led the round, joined by Animo Ventures and Focal.vc. As part of the deal, Andreessen Horowitz partner Joel De La Garza will take a seat on the doxx.net board.
The ADN platform enables individuals and their AI agents to build their own secure, private networks, hold conversations without any intermediary server and sign up without handing over personal details.
It also places agents inside a controlled connectivity environment with integrated threat defences, stopping them from reaching known harmful destinations while they browse and carry out tasks for their users.
The launch targets a growing weakness in the AI landscape. As agents increasingly navigate websites, access services and act with their users’ credentials and data, they risk landing on counterfeit login pages, malware hosts or other hostile sites.
doxx.net addresses this with DNS-level protection that stops connections to both established and newly emerging threats. During its closed beta, which began in December 2025, the platform intercepted over 38m threats.
Within the network, agents receive the same standing as their human users. Each gains its own network identity, private links to people and other agents, and the means to shape its own network via a complete API with built-in MCP support.
The company says no rival treats humans and agents as equals on infrastructure owned entirely by a single firm.
doxx.net operates a separate, sovereign internet layer complete with its own DNS root, IP address space, encrypted mesh and agent-led network configuration. Its capabilities span agents that can build networks, lease IP addresses and set firewall rules; peer-to-peer encrypted calls, video, messaging and file sharing; DNS filtering that pairs 30 filter lists with a neural network; six covert protocols that disguise traffic as everyday browsing where VPNs face restrictions; anti-fingerprinting; onion routing; and a parallel naming system offering 196 custom top-level domains alongside a dedicated certificate authority.
The service runs on the company’s global backbone, with native apps for iOS, macOS and Android, plus support for Windows and Linux. It is designed for a broad audience, from casual users seeking private browsing to technically advanced users linking home networks and agents, as well as journalists in censored countries trying to reach the open web.
Describing the first call made over the network, doxx.net founder and CEO Barrett Lyon said, “Have you ever had your agents configure your network, lease public IP addresses, and set up your security policy, to then discover you can call your friends through your own private network with no one in the middle? No record of the call? No phone company involved, where your phone is also the server?” He added, “That was our first freedom call.”
Lyon added, “The industry sells privacy as a feature while routing your traffic through rented infrastructure they don’t own and can’t verify. We physically built something different: a platform where privacy comes from the architecture itself, not a policy document. We do that so people and agents using the network, not third parties, set the terms of their privacy. They know what you search, where you go, and who you talk to. We don’t. And we built the network so we never can.”
Andreessen Horowitz partner Joel De La Garza said, “The internet was never designed for privacy. doxx.net has built a one-stop privacy stack from first principles, delivering truly private security and communications capabilities, so humans and AI agents can run on a network that is private by architecture, not by marketing promise.”
