Welcome to this edition of the AI Security Newsletter. This week highlights how AI security is becoming a systems problem: models are getting stronger, agents are getting more operational authority, and governance is moving from policy documents into runtime controls. We cover new research on why prompt injection works, real-world evidence that narrow and well-instructed…

Welcome to this edition of the AI Security Newsletter. This week, the biggest theme is the shift from experiments to operational control: AI agents are touching code, identity, cloud operations, security workflows, and even physical robotics, which means the control plane around them now matters as much as the models themselves. We cover new work…

Welcome to this edition of the AI Security Newsletter. This week’s stories show AI security moving from model behavior into the surrounding control plane: release governance, browser policy, endpoint enforcement, agent-skill vetting, and security operations. Frontier-model deployment is becoming a public-policy issue, while enterprise defenders are using AI to triage alerts, assess endpoint intent, and…

Welcome to this edition of the AI Security Newsletter. This week is dominated by one theme: AI agents are becoming real operational actors, and the security stack around them is racing to catch up. We look at agent attestation, agent authorization, skill supply-chain scanning, container and sandbox isolation, AI-assisted vulnerability discovery, and the first signs…

Welcome to this edition of the AI Security Newsletter. This week is about the operating layer around AI agents: how enterprises are bringing frontier models into governed cloud environments, how agent traffic is reshaping fraud and abuse, and how new security tools are trying to control what agents can read, run, and send. The policy…
