No Cloud on the High Seas: Local LLMs for Cybersecurity


Unto Karjalainen

AI assistants can be useful for cybersecurity, but using them often means sending source code, logs, vulnerability details, and other sensitive data to infrastructure operated by a small number of mostly US-based providers.

This talk explores using open-weight LLMs locally for cybersecurity tasks on accessible hardware. Local inference provides data and infrastructure sovereignty: sensitive material stays within an environment you control, without depending on a foreign cloud provider, its policies, or availability.

We will look at practical security applications, hardware requirements, quantization, and the additional freedom open-weight and less-restricted models provide for inherently dual-use security research.

And what better place to demonstrate independence from the cloud than on a ship? The demos will run locally on hardware brought aboard, with the network disabled. No cloud APIs or connection back to shore required.
