What is zero trust architectures?

Zero Trust Architecture (ZTA) is a security framework based on the principle of "never trust, always verify." It assumes that no user or device, whether inside or outside the network perimeter, should be automatically trusted. ZTA requires strict identity verification for every person and device attempting to access resources on the network, regardless of their location. This is often achieved through multi-factor authentication, micro-segmentation, and continuous monitoring. It is commonly used to protect sensitive data and applications from both internal and external threats by minimizing the attack surface and limiting the blast radius of potential breaches.
