# NeMo Guardrails

*/Products/NeMo_Guardrails*

## Product Profile

**How It Flows**: Delivered as an open-source Python library, it integrates directly into the application layer between the user interface and the backend LLM. It operates programmatically by taking text inputs and outputs, evaluating them against custom scripts, and returning validated or blocked responses to the application.
**Operated By**:
- [Machine Learning Engineers](/Products/NeMo_Guardrails/Occupations/Machine_Learning_Engineers)
- [AI Developers](/Products/NeMo_Guardrails/Occupations/AI_Developers)
- [Software Engineers](/Products/NeMo_Guardrails/Occupations/Software_Engineers)
- [Trust and Safety Engineers](/Products/NeMo_Guardrails/Occupations/Trust_and_Safety_Engineers)
**What It Does**: NeMo Guardrails intercepts inputs to and outputs from Large Language Models to enforce safety policies, block jailbreak attempts, and restrict conversational topics. It allows developers to define programmable rules that steer model behavior and filter unsafe or off-topic responses before they reach the end user.
**Primary Buyers**:
- [Enterprise AI Teams](/Products/NeMo_Guardrails/Customers/Enterprise_AI_Teams)
- [MLOps Leaders](/Products/NeMo_Guardrails/Customers/MLOps_Leaders)
- [Chief Technology Officers](/Products/NeMo_Guardrails/Customers/Chief_Technology_Officers)
- [Generative AI Application Vendors](/Products/NeMo_Guardrails/Customers/Generative_AI_Application_Vendors)
