What is Zero Trust?
Zero Trust architecture is a cybersecurity model based on the principle “never trust, always verify.” Unlike traditional security models that assume everything inside a network perimeter is safe, Zero Trust treats every user, device, and connection as potentially hostile. Access is never granted by default; instead, every request must be continuously authenticated, authorized, and validated before access to any resource is permitted.
In practice, Zero Trust is implemented through a combination of strict identity verification, least-privilege access controls, micro-segmentation of networks, and continuous monitoring of user and device behavior. Rather than granting broad access once a user logs in, Zero Trust systems enforce granular policies that limit what each user or device can access based on role, context, and real-time risk signals. Multi-factor authentication, endpoint health checks, and behavioral analytics are common technical pillars of this approach.
