doxx.net has launched the public beta of its Agentic Defined Networking (ADN) platform, which enables users and their AI agents to establish private, secure networks and communicate without intermediary servers. The company also announced it has secured $38 million in Series A funding, led by Andreessen Horowitz, with additional participation from Animo Ventures and Focal.vc. As part of the investment, Joel De La Garza, a partner at Andreessen Horowitz, has joined the doxx.net board.
The ADN platform is designed to provide a parallel, private network where users and agents can browse, transfer files, connect devices, and communicate peer-to-peer. This architecture aims to offer an environment with defined connectivity and integrated threat protection, preventing agents from accessing known malicious destinations while operating on a user's behalf. The company claims that since December 2025, its closed beta has blocked over 38 million threats.
doxx.net emphasizes that its technology is built for a range of users, from individuals seeking private browsing to advanced users connecting home networks and agents, and even journalists in regions with internet censorship. The platform allows agents to configure networks, lease public IP addresses, and establish security policies.
A core feature of the ADN platform is its approach to security in the context of AI agents. As agents increasingly browse, communicate, and act on behalf of users, they face risks such as encountering fake login pages or malware-hosting sites. doxx.net addresses this by providing a policy-defined networking environment with DNS-level threat protection, designed to block malicious destinations before a connection is established. Agents on doxx.net are given their own network identity, private communication channels, and the ability to build their network through a full network API with native MCP support.
The company states that its architecture provides a "sovereign internet" with its own DNS root, IP space, encrypted mesh, and agent-driven networking, eliminating reliance on third-party infrastructure. Key benefits highlighted include Agentic Defined Networking, which allows agents to set up networks, communicate, and configure firewalls. The platform also offers P2P communications for end-to-end encrypted calls, video, chat, and file transfers, without a central communications server.
Threat protection is provided through DNS Protection, which combines 30 filter lists with a neural network to identify and block malicious phishing and malware sites. For users in censored regions, Covert Networking employs six protocols designed to make private-network traffic resemble ordinary web browsing, helping to bypass blocking. Anti-Fingerprinting features are included to mask identifying browser and device details, aiming to prevent tracking across websites.
doxx.net also incorporates onion routing, which routes traffic through multiple servers to separate user identity from activity. The Parallel Internet Ecosystem provides 196 custom top-level domains (TLDs) and its own certificate authority, allowing the network to resolve domains not recognized by the public internet, without third-party involvement. The company asserts that this design ensures privacy is inherent to the architecture, rather than relying on policy documents or routing traffic through rented, unverifiable infrastructure.
