Lennart Henke

As a working student at secunet Security Networks AG, I worked in the Public Authorities divison on applied AI involving locally hosted LLMs. I developed a proof-of-concept safety proxy for LLM traffic using Granite Guardian and gpt-oss-safeguard, and created a prototype meeting summarisation service combining Whisper transcription, speaker diarisation and local LLMs.

MSc in Computer Science at the Technical University of Berlin, with a focus on security and systems. Highlights so far include building a minimal operating system from scratch, working on embedded security by attacking a bare-metal RISC-V firmware, and exploring topics like machine learning for security, compilers and cloud computing.

As a working student at Fraunhofer FKIE, I was part of the Cyber Analysis & Defense (CA&D) department, specifically in the Software and Firmware Security team. My main contributions included building the IPC plugin, contributing to FACT - the open-source firmware analysis framework of the department - and supporting the team's research.

BSc in Computer Science at the University of Bonn, where I first got into information security. During my studies, I build an inter-process communication tool that led to a working student position at the Fraunhofer Institute. I wrote my bachelor's thesis on symbolic execution, exploring how program paths can be analyzed systematically.
