A New Era in Privacy: doxx.net Raises $38 Million to Tame AI Agent Misadventures on the Internet
In a significant move to address growing concerns over AI agent security, Miami-based startup doxx.net has secured a whopping $38 million in funding. The company’s innovative Agentic Defined Networking (ADN) platform is now available in open beta, promising to revolutionize the way agents interact with the internet.
The ADN platform creates a parallel, private networking environment that allows both human users and AI agents to connect, communicate, and browse without relying on central intermediary servers. These servers have long been a vulnerability, providing a single point for interception and surveillance, artificial privacy guarantees that are often more policy than fact, and an increased risk of the agent landing on malicious destinations.
doxx.net’s CEO, Barrett Lyon, emphasizes that their platform is built with privacy by design, rather than relying on marketing promises. “The industry sells privacy as a feature while routing your traffic through rented infrastructure they don’t own and can’t verify,” he explains. “We physically built something different: a platform where privacy comes from the architecture itself, not a policy document.”
ADN provides serverless P2P communication with end-to-end messaging and file transfers, in-built threat protection that blocks malicious destinations, malware, and phishing sites, agent integration and API control, and native apps for iOS, macOS, Android, Windows, and Linux. The platform also boasts its own naming system, certificate authority, and parallel internet ecosystem, allowing customers to run on a private network with their own infrastructure.
One of the key features of ADN is its ability to block threats at the DNS level, preventing agents from connecting to known malicious destinations. doxx.net claims to have blocked over 38 million threats since December 2025 in closed beta.
The funding round was led by Andreessen Horowitz, with participation from Animo Ventures and Focal.vc. Joel De La Garza, partner at Andreessen Horowitz and board member at doxx.net, notes that “the internet was never designed for privacy.” He praises doxx.net’s innovative approach to delivering truly private security and communications capabilities.
As the use of AI agents continues to grow, concerns over their security and potential for misadventures on the internet are becoming increasingly pressing. doxx.net’s ADN platform represents a significant step forward in addressing these issues. By providing a secure and private environment for both human users and AI agents, doxx.net is setting a new standard for online interactions.
For those looking to protect their digital assets from AI agent-related threats, the takeaway is clear: look for platforms that prioritize privacy by design, rather than relying on policy documents or marketing promises. By doing so, you can ensure that your online activities remain secure and private, even in an increasingly complex digital landscape.
