AI Agent Security Control
In late March, two independent developers publicly released tools designed to solve the same quiet problem: AI agents, left to their own devices, can do things you didn't intend. The first appeared on March 20th — a project called Unwind, a security proxy built and run on a Raspberry Pi, shared on Hacker News by its creator. It scored modestly (a 3, in HN terms), which means it found its audience without setting anyone on fire. Five days later, on March 25th, a more formalised version of the same idea surfaced on the MachineLearning subreddit: AgentGuard, described as a policy engine and proxy that controls what AI agents are permitted to do. That one landed a 7.6, suggesting slightly more traction among people who think about these problems professionally. Two builders, one week apart, arriving at the same architectural answer — a proxy layer sitting between the agent and the world, with a rules engine deciding what gets through.
If confirmed as a genuine emerging pattern rather than coincidence, here is what this means. The agent security problem is becoming visible enough that developers are starting to build infrastructure around it without being asked, which is usually how the market signals that enterprise tooling is six to twelve months behind reality. The specific architecture — a proxy plus policy engine — tells you something important: people don't trust the agents themselves to self-govern, so they're reaching for the same network-layer controls we applied to APIs and microservices a decade ago. That has real implications for organisations deploying agentic workflows, because it suggests a new attack surface and a new compliance question are arriving simultaneously. The second-order effect is that any platform selling AI agent capabilities will eventually need to answer how their system interacts with this kind of external control layer, or provide one natively.
Watch for either of these projects gaining significant GitHub stars, forks, or corporate backing in the next thirty days — that would confirm the problem is real enough to attract serious attention rather than just curious builders on a weekend.
