Zero Trust Architecture is a cybersecurity model that rethinks traditional security by eliminating the concept of trust within a network. It operates on the principle that no entity, whether inside or outside the network, is trusted by default. Every access request must be verified and authenticated before access is granted.

Implementing Zero Trust Architecture significantly reduces the risk of data breaches and unauthorized access by verifying every access request. It strengthens overall security, helps organizations meet regulatory requirements through strict access controls, and minimizes risks posed by insider threats by continuously monitoring user activities.

Transitioning to Zero Trust Architecture can be complex and time-consuming, requiring significant changes to existing IT infrastructure and processes. It often involves deploying advanced security technologies and continuous monitoring tools, which can be resource-intensive. Additionally, strict access controls may impact user experience, necessitating a balance between security and usability.
