Founded by Belgian security engineers Mathieu Huysman and Tim De Wachter, Cyrex was born from the "hacker mindset" of the bug bounty scene. Their mission was to defend game publishers against the specialized threats that traditional firms often overlook, treating games as the complex, high stakes software systems they truly are.
Today, that mission is driven by a bolstered leadership team of industry veterans, including Orad Elkayam, Zoi Vitsentzou, and Rui Molefas, who oversee a global force of over 30 elite engineers. Together, they have established Cyrex as the premier security partner for the industry's most recognizable titans, protecting the massive player ecosystems of Amazon Games, Tencent Global, Warner Bros. Games, Funcom, and Techland.
By simulating real world attacker behavior and providing deep tier stress testing, from dedicated back end solutions to client side logic, Mat, Tim, and their executive team ensure that the world's most successful titles remain fair, secure, and resilient in an increasingly social and financialized gaming landscape.
