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. References: [Netskope Secure Forwarder], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 3: Steering Configuration, Lesson 3: Secure Forwarder.

An App Instance is a feature in the Netskope platform that allows you to define and identify different instances of the same cloud application based on the domain name or URL. For example, you can define an App Instance for your enterprise Google Drive instance (such as drive.google.com/a/yourcompany.com) and another App Instance for your personal Google Drive instance (such as drive.google.com). This way, you can differentiate between them and apply different policies and actions based on the App Instance. You would want to define an App Instance to achieve this level of granularity and control over your cloud application activities. Creating an API Data Protection Policy for a personal Box instance, enabling the instance_id attribute in the advanced search field, or differentiating between an enterprise Google Drive instance vs. an enterprise Box instance are not valid reasons to define an App Instance, as they are either unrelated or irrelevant to the App Instance feature. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 5: Real-Time Policies, Lesson 4: App Instances.

Netskope’s NewEdge Security Cloud Network Infrastructure is a global network that powers the Netskope Security Cloud, providing real-time inline and out-of-band API-driven services for cloud and web security. Three statements that are correct about Netskope’s NewEdge Security Cloud Network Infrastructure are:

It includes direct peering with Microsoft and Google in every data center. This means that Netskope has established high-speed, low-latency connections with these major cloud service providers, ensuring optimal performance and user experience for their customers. Direct peering also reduces the risk of network congestion, packet loss, or routing issues that may affect the quality of service.

It is a private security cloud network that is massively over provisioned, highly elastic, and built for scale. This means that Netskope owns and operates its own network infrastructure, without relying on third-party providers or public cloud platforms. Netskope has invested over $150 million to build the world’s largest and fastest security private cloud, with data centers in more than 65 regions and growing. Netskope can dynamically scale its network capacity and resources to meet the growing demand and traffic volume of its customers, without compromising on security or performance.

It delivers a single, unified network with no surcharges or reliance on public cloud infrastructure or virtual PoPs. This means that Netskope provides a consistent and transparent network service to its customers, regardless of their location or device. Netskope does not charge any additional fees or hidden costs for accessing its network services, unlike some other providers that may impose surcharges based on geography or bandwidth usage. Netskope also does not use virtual points of presence (PoPs) that are hosted on public cloud platforms, which may introduce latency, complexity, or security risks.

Shadow IT is the term for the unauthorized use of IT resources and functions by employees within an organization. It can include cloud services, software, and hardware that are not approved or managed by the IT department. Two use cases that would be considered examples of shadow IT within an organization are: an unsanctioned Microsoft 365 OneDrive account being used by a corporate user to upload sensitive data and an unsanctioned Google Drive account used by a corporate user to upload non-sensitive data. In both cases, the corporate user is using a personal cloud storage service that is not sanctioned by the organization to store work-related data. This can introduce security risks, such as data leakage, data loss, compliance violations, malware infections, etc. The IT department may not have visibility or control over these cloud services or the data stored in them. References: What is shadow IT? | CloudflareWhat is Shadow IT? | IBM
