Design innovation without compromising safety

Cybersecurity shouldn't hinder your projects; it should strengthen them. I help SMEs and industrial players integrate security into the core of their software and embedded systems. Secure development, applied cryptography, code review, and hardware security: I apply my specialized expertise to provide long-term protection for your products, data, and intellectual property.

Who am I ?

My name is Pascal Perrenoud. I am a cybersecurity engineer, holding a Bachelor's degree from HEIG-VD in Yverdon-les-Bains and a Master's degree from HES-SO in Lausanne. I worked for two years as an academic assistant at HEIG-VD before completing my Master's internship at CSEM in Neuchâtel, where I honed my skills in demanding technological environments. My areas of expertise include secure software development, applied cryptography, and hardware security. Alongside my professional activities, I cultivate a passion for music, which fuels my creativity and my sense of rigor.
