Elastic NL Meetup: Building Authorization for Agentic RAG Systems

An Elastic Netherlands User Group evening on authorisation for agentic RAG, co-hosted with AuthZed at Elastic's Amsterdam office. Sohan Maheshwar, Lead Developer Advocate at AuthZed, explains why enterprise RAG with AI agents needs fine-grained authorisation, how the Google Zanzibar model and relationship-based access control (ReBAC) work under the hood, and how to apply them with pre- and post-filtering. Includes live coding with Elasticsearch, LangChain and SpiceDB. A second talk is still to be confirmed. Doors 17:45, talks from 18:05, pizza and networking until 20:30 at Keizersgracht 281. Free, RSVP on Meetup. Why go: permissions are what stop most agent pilots reaching production, and this is a code-level answer, not a slide deck. Best for backend and platform engineers building RAG or agent features.
