About Janvier

With over 21 years of experience in IT, cybersecurity, and recently graduated with an Executive MBA in Cybersecurity, I am a bilingual French-English professional with in-depth expertise in risk management, data protection, and regulatory compliance. I have implemented security strategies that reduced incidents by 40% and led audits that strengthened company defenses. Recognized for my analytical skills and ability to anticipate threats, I am also a leader capable of training and motivating high-performing teams. My goal is to ensure the security of information systems while supporting the strategic objectives of the company.
