In this scenario, there are three probable causes for the issue of users not being able to access external websites from their browsers after attempting to steer traffic to Netskope using GRE tunnels. One cause is that the configured GRE peer in the Netskope platform is incorrect, which means that the Netskope POP that is supposed to receive the GRE traffic from the customer's network is not matching the IP address of the customer's router that is sending the GRE traffic. This will result in a failure to establish a GRE tunnel between the customer and Netskope. Another cause is that the corporate firewall might be blocking GRE traffic, which means that the firewall rules are not allowing the GRE protocol (IP protocol number 47) or the UDP port 4789 (for VXLAN encapsulation) to pass through. This will result in a failure to send or receive GRE packets between the customer and Netskope. A third cause is that the route map was applied to the wrong router interface, which means that the configuration that specifies which traffic should be steered to Netskope using GRE tunnels was not applied to the correct interface on the customer's router. This will result in a failure to steer the desired traffic to Netskope. The pre-shared key for the GRE tunnel is incorrect is not a probable cause for this issue, as GRE tunnels do not use pre-shared keys for authentication or encryption. Netskope does support GRE tunnels, so this is not a cause for this issue either.Reference:[Netskope Secure Forwarder],Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 3: Steering Configuration, Lesson 3: Secure Forwarder.

In this scenario, a user is connected to a cloud application through Netskope's proxy, which is a deployment method that allows Netskope to intercept and inspect the traffic between the user and the cloud application in real time. In this case, Netskope can collect and display various information about the user and the cloud application at Skope IT, which is a feature in the Netskope platform that allows you to view and analyze all the activities performed by users on cloud applications. Some of the information that is available at Skope IT are: username, device location, account instance, URL category, user activity, and cloud app risk rating. Username is the name or identifier of the user who is accessing the cloud application. Device location is the geographical location of the device that the user is using to access the cloud application. Account instance is the specific instance of the cloud application that the user is accessing, such as a personal or enterprise instance. URL category is the classification of the web page that the user is visiting within the cloud application, such as Business or Social Media. User activity is the action that the user is performing on the cloud application, such as Upload or Share. Cloud app risk rating is the score that Netskope assigns to the cloud application based on its security posture and compliance with best practices. Destination IP, OS patch version, file version, and shared folder are not information that is available at Skope IT in this scenario, as they are either unrelated or irrelevant to the proxy connection or the Skope IT feature.Reference:[Netskope Inline CASB], [Netskope Skope IT].

When working with traffic from applications with pinned certificates, you should add an exception to the steering configuration to bypass them. Pinned certificates are a security technique that prevents man-in-the-middle attacks by validating the server certificates against a hardcoded list of certificates in the application. If you try to intercept or inspect the traffic from such applications, they will reject the connection or display an error message. Therefore, you should add the domains used by certificate-pinned applications as exceptions in your steering configuration, so that they are not steered to Netskope for analysis and enforcement.Reference:Certificate Pinned ApplicationsCreating a Steering Configuration

To collect the logs from the client machine when you have an issue with the Netskope client connecting to the tenant, two ways that you can use are: from the Netskope client UI About page and from the command line using the nsdiag command. From the Netskope client UI About page, you can click on the ''Collect Logs'' button to generate a zip file containing all the relevant logs and configuration files from the client machine. You can then send this zip file to Netskope support for troubleshooting. From the command line, you can use the nsdiag command with various options to collect different types of logs and diagnostic information from the client machine. For example, you can use nsdiag -l to collect all logs, nsdiag -c to collect configuration files, nsdiag -t to collect traffic statistics, etc. You can also use nsdiag -h to see all available options and usage instructions. You can then send the output files to Netskope support for troubleshooting.Reference:Netskope Client Configuration overviewInstall and Test the Client - Netskope Knowledge Portal

If you consume application infrastructure (middleware) capabilities by a third-party provider, then the cloud service model that you are using in this scenario is PaaS, which stands for Platform as a Service. PaaS is a cloud service model that provides customers with a platform to develop, run, and manage applications without having to deal with the underlying infrastructure or software. PaaS typically includes middleware capabilities such as databases, web servers, development tools, integration services, etc., that customers can use to build and deploy their applications faster and easier. MaaS, DaaS, and SaaS are not cloud service models that match this scenario, as they stand for different types of services. MaaS stands for Monitoring as a Service, which is a service that provides customers with tools to monitor and manage their cloud resources and performance. DaaS stands for Desktop as a Service, which is a service that provides customers with virtual desktops that they can access from any device or location. SaaS stands for Software as a Service, which is a service that provides customers with software applications that they can use over the internet without installing or maintaining them.Reference:[PaaS], [MaaS], [DaaS], [SaaS].
