What is Zscaler's approach to network segmentation?

Zscaler's approach to network segmentation is centered around enforcing access controls based on user needs. This means that access to applications and resources is granted based on a user's specific role, identity, and the principle of least privilege. By aligning access to user requirements, Zscaler effectively minimizes potential attack surfaces and reduces the risk of unauthorized access. This user-centric model supports dynamic access policies tailored to individual users or groups, ensuring they only see and interact with the resources necessary for their work.

In contrast, restricting all access to applications would be overly prohibitive and could hinder productivity, while allowing open access to all network resources would expose the network to significant security risks. Isolating all servers from user access might enhance security but would create functional challenges, as users often need to access multiple server resources as part of their roles. Therefore, Zscaler's approach effectively balances security with accessibility by implementing selective access controls.
