This video covers how Guardrails can check, filter, and sanitize texts to protect against unwanted outputs, sensitive information, and off-topic requests. It includes a detailed walkthrough of each Guardrail type, real-world examples, and a workflow demonstration for cleaning and validating customer messages. You are also invited to explore this template to play around with and to understand guardrails better. Time to upgrade your security for your AI agents, which is absolutely essential and non-negotiable.
