This post was fully written by me. Typos and grammar errors were checked with Claude.

In my last post I mentioned that “security is not optional”, touching briefly on the lethal trifecta, data leakage and sandboxing. With this post I want to show some concrete examples of why security is extremely important, especially when rolling out agentic workflows in enterprises.

Security, as always, is for most people an afterthought. In the agentic era, it is actually very scary what you can achieve with minimal effort. This motivated me in recent months to show customers and our colleagues in trainings what attacks can look like. Their faces during the demo are always priceless. So, in the words of Steve Yegge, be scared!
