RAG

How retrieval augmented generation (RAG) handles sensitive data, from embeddings and vector stores to retrievers, rerankers and access policy.

Are embeddings personal data? RAG and GDPR explained

Do not assume an embedding is anonymous. Learn what a RAG pipeline copies, how to delete a person's data from a vector store, and why tokenizing before embedding helps....

Reranker Needed in RAG
  • PII Masking, RAG

Why Is a Reranker Needed in RAG If We Have a Retriever?

Enterprise RAG pipelines have two stages recall and precision. The retriever handles recall. The reranker handles precision. Skipping the reranker, or misplacing security controls around it, is where most accuracy and data exposure problems begin....

Retriever Matters
  • LLM, RAG

Why Your Retriever Matters More Than Your LLM in RAG

Most RAG data exposure happens before the LLM processes a single token. The retriever decides what sensitive data the model sees, and most teams are not securing it. Here is where the gaps are and how to close them....

Authorization Is No Longer Static

A CEO's agent passed every access check, and still put M&A targets, individual salaries, and unreleased roadmap into a draft headed for a dozen inboxes. Here's why static authorization is the wrong model for agentic AI....
