The traditional perimeter security model has limitations in today's digital transformation and hybrid cloud infrastructure, where data is spread across multiple locations and users access resources from outside the IT department's control. The Zero Trust security model treats users, systems, and network traffic as fundamentally untrusted, requiring explicit authentication, authorization, and encryption for each access request. This approach provides robust protection against data breaches, insider threats, and cyber attacks, while also improving system and network visibility, supporting continuous digital transformation, providing more access control of cloud and container environments, and making staying compliant seamless. By adopting Zero Trust, companies can enhance their security posture, increase efficiency, and meet compliance requirements, ultimately protecting people, devices, apps, and data wherever they're located.
