About

I want to bring my knowledge of offensive security to help my clients organically improve their security posture. I assist with penetration testing, threat modeling, attack surface management, red teaming and awareness measures. In doing so, I benefit from my experience of many years in a wide variety of activities in companies of all sizes and industries.
