What is Google AI Threat Defense?

Google AI Threat Defense is a security capability aimed at artificial intelligence workloads themselves — the models, agents, prompts, and data pipelines that make up an AI application — rather than only the infrastructure beneath them. It inspects model inputs, responses, and agent actions for attacks such as prompt injection, tool abuse, and data exfiltration, and detects and blocks activity that breaches policy before it reaches the model or downstream systems.
