    To power the firewalling for our agents so that they couldn't contact arbitrary services, I build netfence. It's like Envoy but for eBPF filters. It allows you to define different DNS-based rules that are resolved in a local daemon to IPs, then pushed to the eBPF filter to allow traffic. By doing it this way, we can still allow DNS-defined rules, but prevent contacting random IPs. There's also no network performance penalty, since it's just DNS lookups and eBPF filters referencing memory. It also means you don't have to tamper with the base image, which the agent could potentially manipulate…

    Howdy folk, I've been building this project as both a side project and my job for a little while now. The rationale behind it is while wireguard is a fantastic protocol cryptographically it leaves a lot to be desired when it comes to enrollment and end user device security. Obviously instead of using an off the shelf solution like tailscale, I decided to reinvent the wheel which has honestly been quite fun with learning about eBPF, and recently clustering and HA with etcd! The most recent version (in the docker container) contains about 6 months of very new work bringing it all from sqlite3…

    Hey HN! This is Adil, Salman and Jose and and we’re behind archgw [1]. An intelligent proxy server designed as an edge and AI gateway for agents - one that natively know how to handle prompts, not just network traffic. We’ve made several sweeping changes so sharing the project again. A bit of background on why we’ve built this project. Building AI agent demos is easy, but to create something production-ready there is a lot of repeat low-level plumbing work that everyone is doing. You’re applying guardrails to make sure unsafe or off-topic requests don’t get through. You’re clarifying vague…

    Hi HN, Matvey, Ildar, Joey, and Dominik here. If you're building LLM agents that use tools, you're probably worried about prompt injection attacks that can hijack those tools. We were too, and found that solutions like prompt-based filtering or secondary "guard" LLMs can be unreliable. Our thesis is that agent security should be handled at the network level between the agent and the LLM, just like a traditional web application firewall. So we built Archestra Platform: an open-source gateway that acts as a secure proxy for your AI agents. It's designed to be a deterministic firewall against…
