• Voice AI Security: Adversarial Audio, Ultrasonic Injection, and Attacks on Speech-Enabled AI Agents

  Voice-enabled AI agents inherit a distinct attack surface that text-focused security misses entirely. Adversarial audio perturbations fool ASR pipelines invisibly, ultrasonic commands exploit microphone analog front-ends, and voice authentication breaks when attackers control TTS. Here's the threat model practitioners need.

• Circuit Breakers for AI Agents: Designing Controllability, Action Budgets, and Emergency Stops

  Your agent will eventually get confused. The question is whether it fails safely or catastrophically. Here are the engineering patterns — borrowed from distributed systems and adapted for AI agents — that make the difference.

• Zero-Trust Architecture for AI Agent Deployments: Never Trust, Always Verify — Even Your Own Agents

  Zero-trust was designed for human users on networks. AI agents break its assumptions: they act autonomously, spawn child agents, inherit permissions, and run long-lived sessions. Here's how to adapt zero-trust principles specifically for multi-agent and LLM deployment contexts.
