Guardrails are security mechanisms integrated into Devic that allow you to control, filter, and supervise the behavior of AI assistants before they process user instructions.
Their purpose is to ensure that models operate within safe, legal, and appropriate boundaries for production environments. In real-world scenarios —especially in companies handling sensitive data, regulated processes, or critical information— guardrails are essential to prevent risks such as:
  • Unintentional exposure of personal or confidential data.
  • Generation of harmful, toxic, or inappropriate content.
  • Model manipulation through jailbreak attempts.
  • Out-of-context responses or deviations from business objectives.
  • Unsafe instructions that could trigger tools or processes incorrectly.
Devic allows you to add guardrails to each assistant, creating an additional layer of protection before the user’s message reaches the model (LLM). Access to guardrail configuration in the assistant
