Practical LLM Use Cases for Security

Session en Anglais - Débutant

LLMs are often pitched as coding co-pilots, but their true long-term value for engineering teams can be in tackling the tedious work nobody wants to do.

This session will present a selection of practical, "boring" LLM use cases, such as the enforcement of security policies and training. We'll have a critical look at what to trust and how to verify an LLM's output when it comes to code and knowledge transfer.
