We're worried about our crazy AI adoption!


Is something I've heard a lot of CISOs and ProdSec teams really worry about. And rightfully so. I see engineering teams start to plug-in LLMs into everything without thinking about security or privacy. This risk is heightened with Agents, because now, LLMs can literally call (sometimes extremely powerful) functions that can execute actions on your internal systems, APIs and more. And the AI landscape is massive and getting bigger every day. 

This scares a lot of people and seems overwhelming. But let's break things down into smaller problems to make things easier to handle. 

In my experience, 80%+ companies out there are building two types of apps: 

* RAG (Retrieval Augmented Generation) apps  where the org's internal datasets are loaded into vector databases and LLMs use that as context to generate responses for chatbots, internal applications and more
