Cyber threats are multiplying in a digital world where everything is becoming interconnected. Web2 and Web3 now share the same vulnerabilities: centralized cloud infrastructures, poorly secured connected devices, and cryptographic algorithms that are becoming obsolete in the face of quantum computing. Traditional solutions are no longer sufficient. They fail to monitor, protect, and validate in real time. Naoris Protocol offers a new approach. Its Decentralized Post-Quantum Infrastructure operates beneath blockchain layers to secure both Web2 and Web3 at their core. This article explores today’s cybersecurity challenges, explains the concept of decentralized security, and details the technical pillars and strategic advantages of the Naoris Protocol model.
