Video games / Denuvo Anti-Cheat

Anti-Tamper

Anti-Tamper is the foundational game security layer in the Denuvo by Irdeto anti-cheat portfolio, preventing client-side modification and reverse engineering to secure game binaries and memory, making cheat creation significantly harder.

The modern gaming industry is a multi-billion-dollar market where fair competition and protected IP are essential. Most cheats begin with client-side tampering and reverse engineering, leading to player frustration and churn. Anti-Tamper strengthens game security by making reverse engineering materially harder and securing game binaries and memory against common attack methods such as debugging, memory editing and code injection.
