Which areas should be localized when troubleshooting an Internet access issue with Zscaler?

When troubleshooting an Internet access issue with Zscaler, it is essential to consider multiple areas that can impact connectivity and functionality. The inclusion of the end user's device, local network, corporate firewall, and Zscaler Cloud is vital for a comprehensive troubleshooting approach.

The end user's device is the starting point, as issues such as browser settings, local software configurations, or endpoint security solutions can affect access. Next, the local network needs to be evaluated because it can introduce problems based on network congestion, DNS resolution issues, or misconfigurations in local routers and switches.

The corporate firewall plays a crucial role as well, as it might be inadvertently blocking legitimate traffic meant for Zscaler or could have policies that restrict access to certain destinations. Lastly, integrating the Zscaler Cloud into the troubleshooting process is necessary because the issue could be on Zscaler's end, such as outages or service disruptions.

By examining all these areas together, you can systematically identify and resolve the root cause of the Internet access issue, making this option the most comprehensive and effective for troubleshooting in a cloud-based security environment like Zscaler.
