I’m Joel Aviad Ossi, founder and managing director of WebSec BV, a cybersecurity company based in the Netherlands and the United States. I focus on offensive security and have experience with penetration testing, red teaming, vulnerability research, and reverse engineering. I’ve published over 25 CVEs and reported more than 500 responsible disclosures.

I have a strong passion for Cybersecurity R&D. I’m driven by the challenge of developing new methods and techniques to bypass, evade, or neutralize modern security challenges such as EDR and XDR solutions, with the goal of gaining an edge during red teaming and vulnerability assessments.
