Renaud Feil
CEO | Co-Founder of Synacktiv
From the very start of his career, Renaud has been driven by a relentless passion for technical challenges. The harder the problem, the more fun it is to break.
Following this mantra, Synacktiv has grown into a team of 170+ security experts, specializing in Red Team operations, reverse engineering, vulnerability research, security tool development, and incident response.
His team has had the thrill of breaking into the systems of hundreds of companies, uncovering vulnerabilities in some of the weirdest computer systems, and helping organizations defend against some of the most sophisticated attacks in recent years.
Renaud may have swapped CTF competitions for customer meetings, but his hacker spirit remains intact. He still believes cybersecurity is the most fascinating field mankind has ever created and continues to lead Synacktiv with the same curiosity, mischief, and love for breaking things that got him into hacking in the first place.
