I recently had an interesting conversation at a KCD about OpenClaw with one of the attendees, and they remarked that they wouldn’t put an agent in their network, because “we don’t know what that thing really does”. That got me thinking; agentic autonomy has huge potential to automate tasks previously needing humans, but at the same time, that capability introduces new operational and security challenges. This inspired me to start a passion project to create a network boundary for AI agents.
You might be thinking, that’s why we have guardrails! While it’s important to understand agentic intent to influence generation, it’s also necessary to control network access for agentic tools. Enforcing network traffic security is fundamental, and there are already many solutions available for that purpose.
How about if we built a network boundary that was both enforced and observable at the same time, without needing to introduce entirely new infrastructure? The answer turned out to be surprisingly simple. Use two mature open source components that are already common in cloud native environments: NGINX as the traffic control plane and OpenTelemetry as the audit plane. They allow us to gain observability and create an efficient boundary where we can implement fine-grained, application-aware traffic shaping rules.

Because NGINX sits on both sides of the flow, it performs the reverse proxy role for inbound traffic, terminates TLS, and forwards requests for the agent. For outbound traffic, the same instance acts as a forward proxy through which every agent …
