Zero Trust marks a significant shift in [cybersecurity](https://www.o2oh.com/glossary/cybersecurity), moving from perimeter-based defense to continuous verification. Its core principle is: "Never trust, always verify."

Unlike traditional models that trust users inside the network, Zero Trust assumes potential compromise and enforces strict authentication, authorization, and encryption for every access request.

By applying least-privilege access and micro-segmentation, Zero Trust reduces the attack surface and limits [lateral movement](https://www.o2oh.com/glossary/lateral-movement) in decentralized environments.

In manufacturing, Zero Trust is essential for securing the [IT/OT convergence](https://www.o2oh.com/glossary/it-ot-convergence). It protects vulnerable legacy machinery through micro-segmentation, preventing lateral movement during [cyberattacks](https://www.o2oh.com/glossary/cyber-attacks). Strict access controls for remote maintenance help ensure operational continuity and protect intellectual property from [supply chain](https://www.o2oh.com/glossary/supply-chain) vulnerabilities in connected [smart factories](https://www.o2oh.com/glossary/smart-factory).
