[Advent of Agents] Day 23: Model Armor: AI Security Firewall for Agents

[abraha...@google.com]

Hi everyone,

Day 23 of Google's Advent of Agents — Season 2 is now live! 🌸

As AI agents gain autonomy, protecting them against prompt injections and data leakage is no longer optional but essential for production safety. Discover how Google Cloud Model Armor acts as a powerful security firewall to safeguard your agents with a robust, model-agnostic defense-in-depth strategy.

Today's Highlights:

• Proactively detect and block malicious prompt injections and jailbreak attempts before they reach your model.
• Prevent sensitive data leakage through automatic PII redaction and malicious URL detection in both prompts and responses.
• Leverage a model-agnostic REST API to enforce consistent security policies across any LLM or cloud environment.
