What are the roles of zero-trust architecture in network solutions?

Zero-trust architecture is a security concept centered around the idea that organizations should not automatically trust any user or device inside or outside their network. It assumes that threats could exist both inside and outside the network. With zero-trust architecture, strict access controls are implemented, requiring verification for all users and devices trying to connect to the network, regardless of their location or network environment. This approach enhances security by minimizing the attack surface, reducing the chances of unauthorized access, and providing visibility and control over network traffic and assets.
