In this session, we'll explore the development of an in-house threat modeling assistant that leverages Large Language Models through AWS Bedrock and Anthropic Claude. Learn how we're building a private solution that automates and streamlines the threat modeling process while keeping sensitive security data within our control. We'll demonstrate how this proof-of-concept tool combines LangChain and Streamlit to create an interactive threat modeling experience. Join us to see how modern AI technologies can enhance security analysis while maintaining data privacy.
