Cyber threats are multiplying in a world where digital systems are becoming increasingly interconnected. Traditional architectures, based on implicit trust and centralized points of control, are no longer sufficient to protect data and critical infrastructures. The Zero Trust model emerges as a clear response to these flaws: it relies on continuous verification, granting no user or device default trust. To go further, blockchain offers an ideal foundation. With its Sub-Zero architecture, Naoris Protocol turns this promise into reality. It creates a decentralized, post-quantum, self-validating infrastructure capable of securing both Web2 and Web3 systems in real time, without a single point of failure.
