What is the primary function of ZTunnel in traffic handling?

ZTunnel plays a crucial role in traffic handling by acting as a secure tunnel that intercepts traffic at the network level. This function allows Zscaler's cloud-based services to inspect and manage the data traffic that flows to and from endpoints. By intercepting this traffic, ZTunnel ensures that it can apply security policies effectively, perform threat intelligence checks, and enforce compliance regulations in real time.

This capability is essential for providing a seamless and secure user experience, particularly for organizations that operate in varied network environments, including remote work scenarios. The traffic interception facilitates not only the identification and mitigation of potential threats but also the collection of analytics and logs for further examination, enhancing the overall security posture of an organization.

The other choices address different functionalities that Zscaler provides, but they do not center on the core purpose of ZTunnel. For example, securing the endpoint device relates more to device-specific security measures; local caching pertains to performance optimizations that are not inherent to the general traffic handling mission of ZTunnel; and optimizing bandwidth relates more to network efficiency rather than the interception role that ZTunnel fulfills.
