Summary
👤
Senior🎓
Top SchoolCyril Bresch is a hardware and software security leader with 8 years of experience, currently co-founding and serving as CTO of Wotena to rethink silicon security from reactive patching to proactive, continuous defense. His background spans industry and academia—PhD-driven research on control-flow integrity and cyber-physical systems at Université Grenoble Alpes and the University of Arizona, plus hands-on engineering at SiFive where he quantified timing side-channels and designed Spectre-resistant branch predictors and IOMMU cache architectures. He combines deep compiler, pipeline and formal verification experience (JasperGold, UVM) with practical embedded systems work, from LLVM-based mitigations to IoMT prototypes. Based in Marseille, he blends researcher rigor with product-building instincts and a penchant for turning complex hardware threats into measurable, automatable defenses. An often-overlooked strength is his cross-layer fluency: he reasons across silicon, firmware and toolchains to deliver end-to-end security guarantees.
