Doxx.net announced a $38 million Series A funding round led by Andreessen Horowitz to expand its Agentic Defined Networking platform. The service, which moved from closed beta to public availability on October 1, 2026, aims to secure AI agent communications.
Why it matters
The platform addresses the vulnerability of AI agents that rely on traditional networks, which often depend on intermediaries. By enabling server-less, encrypted peer-to-peer connections, Doxx.net seeks to minimize the attack surface for independent digital agents.
Doxx.net blocked 38 million potential threats during its closed beta period that began in December 2025. The platform allows users to build private, server-less networks featuring dedicated DNS roots, unique IP allocations, and encrypted communication channels.
The players
Doxx.net
A Miami-based startup building Agentic Defined Networking platforms for server-less, peer-to-peer communication.
Andreessen Horowitz
A Silicon Valley venture capital firm that invests in early-stage technology startups and led this funding round.
Barrett Lyon
The founder and CEO of Doxx.net who leads the firm's efforts in network security and agentic connectivity.
The details
The platform enables users to create private peer-to-peer networks—a direct connection between computers that bypasses centralized intermediaries. Each network includes its own DNS root—the foundational naming system that translates human-readable addresses into machine-readable IPs—and specific IP allocations to isolate traffic. This architecture is designed to protect AI agents by eliminating reliance on the vulnerable relay points found in traditional network configurations.
Timeline
December 2025: The closed beta testing period commenced.
October 1, 2026: The funding round was finalized and the open beta launched.
The Tech Race
This development represents a shift from traditional Software-Defined Networking by moving security logic to the agent layer. It marks a departure from centralized architectures, challenging standard approaches to how independent digital agents connect and authenticate.
Developers and organizations utilizing independent AI agents can now access the public beta to deploy private peer-to-peer networks. This tool replaces the need for server-reliant network infrastructure, potentially reducing security risks associated with third-party service providers.
The takeaway
The firm will utilize its $38 million in new capital to support the transition of its Agentic Defined Networking platform into an open beta. Interested parties should watch the performance metrics of the open beta to see if it sustains the threat-blocking efficiency demonstrated during the closed pilot phase.
