+Map every OWASP GenAI risk to **26 frameworks**, from NIST AI RMF and ISO/IEC 42001 to the EU AI Act and DORA. You can score your coverage, find gaps, and export OSCAL or STIX.

 ## Overview
 
 The OWASP GenAI Data Security Initiative addresses the data security risks unique to Large Language Models, Generative AI, and Agentic AI systems. AI introduces new data surfaces — prompts, context windows, embeddings, vector stores, agent traces, tool payloads — and new failure modes — prompt-driven extraction, cross-session bleed, inference attacks, plugin data drains — that traditional data security frameworks no longer map cleanly onto.
