AutoProber is an open-source hardware security research platform that puts an LLM agent in control of a physical CNC machine to autonomously probe circuit boards. The build uses off-the-shelf parts: a webcam, a USB microscope, a cheap CNC frame, and a probe tip. The agent handles the full hacking workflow — target PCB discovery, microscope-assisted mapping of test points, CNC motion planning with safety bounds checking, and controlled pin probing for UART/JTAG/SWD interfaces. The software stack is pure Python. The agent generates motion commands in a DSL, validates them against hardware safety constraints before execution, and updates an exploration map as it discovers new test points. GainSec posted a demo video showing the arm autonomously locating and probing a router PCB's debug interface without human intervention after initial setup. What makes this genuinely novel isn't the individual components — hobbyists have built CNC probers before — but the LLM-in-the-loop architecture that turns the whole process from a manual expert skill into a semi-automated one. Security researchers who previously needed 15 years of experience to read a PCB layout now have a tutor and co-pilot on the physical bench.

ElevenAgents Guardrails 2.0 is a safety layer built on top of ElevenLabs' voice agent platform, designed for enterprises deploying customer-facing AI voice agents at scale. The core problem it solves: voice agents in production tend to drift, get manipulated through prompt injection, or go off-brand in ways that only surface after something embarrassing happens. Version 2.0 adds three main capabilities: real-time policy enforcement that monitors agent behavior as it happens, prompt injection protection against users trying to manipulate the agent's instructions, and configurable custom rules that enterprises can tailor to their specific compliance or brand requirements. Unlike static guardrails baked into the system prompt, these operate as a live enforcement layer during conversations. The timing matters. As more enterprises put voice agents on their phone lines and websites, the "what could go wrong" list has gotten longer — agents giving wrong pricing, going off-script with sensitive customers, or being jailbroken into saying things they shouldn't. Guardrails 2.0 positions ElevenLabs not just as a voice synthesis platform but as an enterprise-safe agent runtime.
Reviewer scorecard
“The safety constraint validation layer before any CNC motion is the right call and shows the author understands what goes wrong when you mix LLMs with physical actuators. The DSL for motion commands is clean. This is a real research tool, not a toy.”
“Static system prompt guardrails are a band-aid. Having a live enforcement layer that can catch drift and injection attempts as they happen is the right architecture for anything customer-facing. This is the kind of tooling that makes it reasonable to deploy voice agents in sensitive contexts like healthcare or finance.”
“The agent hallucinates PCB pin assignments in about 20% of cases based on the demo, which in a physical system means a bent probe or a shorted component. The hardware cost to build a reliable version is non-trivial, and you still need domain expertise to validate what the agent decides.”
“Guardrails as a paid add-on to your voice agent platform is a strange model — safety shouldn't be upsold. Also, ElevenLabs controlling both the voice synthesis and the safety layer means there's no independent verification that the guardrails are actually working. That's a dangerous single point of trust for enterprise compliance purposes.”
“This is physical AI applied to the supply chain security problem. AI-assisted hardware auditing could eventually make it practical to spot tampered firmware chips or backdoored components at scale — a national security capability currently gated behind a tiny pool of expert humans.”
“Voice agents are the new customer service reps, and companies are learning the hard way that they need guardrails. This is the beginning of a whole category: real-time behavioral safety systems for AI agents. The team that solves this at scale — across providers, not just ElevenLabs — will be enormous.”
“Not my domain, but the demo video is one of the coolest things I've seen this week. The moment the arm autonomously repositions based on the microscope view is genuinely impressive. Niche hardware security tool, but an inspiring proof of concept for physical AI.”
“Brand safety for voice is genuinely underserved. Written AI outputs can be reviewed and filtered; voice interactions happen in real time with no undo. Knowing your agent won't say something off-brand to a live customer is worth paying for, especially for high-volume contact centers.”
