Building on our previous guide, let’s add enterprise-grade security to your AI workflows
In Part 1, we built a basic LangGraph architecture via FastAPI. But before deploying to production, we need robust authentication and security measures.
The article discusses how to enhance the security and authentication processes of AI workflows, particularly those built using LangGraph and FastAPI. It highlights the importance of robust authentication measures, like API keys and JWT tokens, to protect sensitive data and prevent unauthorized access. The guide covers several key aspects of API security, including rate limiting, input validation, and the use of middleware to manage these elements effectively, ensuring that the APIs are reliable and secure for production environments.
