Enable Guardian for External Agents

Use a system property to protect your Language Learning Models (LLMs) with Guardian.

Use the sn_aia.external_agent_guardian_check system property to enable Guardian, which monitors requests sent to Language Learning Models (LLMs) and their responses to help protect you, your users, and your data. There are three types of content that are monitored for:

  • offensive or harmful content
  • prompt injection attempts
  • filtered subjects

Ensure that the sn_aia.external_agent_guardian_check system property does not exist in the System Properties [sys_properties] table, or exists and is set to a value of true.
