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.

To create a policy to quarantine files based on sensitive content in Netskope, you need to include the DLP Profile variable. Here's a detailed explanation of the steps involved:
Access Netskope Admin Console: First, log in to your Netskope admin console.
Navigate to Policies: Go to the Policies section where you can create and manage different types of policies.
Create a New Policy: Click on the option to create a new policy. Select the type of policy you want to create. In this case, it will be a Data Loss Prevention (DLP) policy.
Define Policy Criteria: Define the criteria for your policy. This includes specifying the conditions under which files should be quarantined. You will need to include sensitive content detection as part of the criteria.
Include DLP Profile: The most crucial step is to include a DLP Profile in your policy. The DLP Profile will define the sensitive content that the policy will monitor for. Netskope provides various predefined DLP profiles that you can use, or you can create custom DLP profiles based on your organization's needs.
Set Action to Quarantine: Specify the action to be taken when the policy criteria are met. In this case, you want to quarantine the files. Select the "Quarantine" action from the available options.
Save and Apply Policy: Once you have configured the policy with the DLP profile and action, save the policy and apply it to the relevant users, groups, or organizational units.

The two traffic steering configurations that are supported by Netskope are cloud applications only and all Web traffic including cloud applications. These configurations allow you to control what kind of traffic gets steered to Netskope for real-time deep analysis and what kind of traffic gets bypassed. You can choose one of these options for both on-premises and off-premises scenarios, depending on your network environment and security needs. You can also create exceptions for specific domains, IP addresses, or certificate-pinned applications that you want to bypass or steer regardless of the configuration option.

A SASE (Secure Access Service Edge) solution provides networking functions that go beyond the capabilities of an SSE (Security Service Edge) solution. Specifically, a SASE solution integrates:
* Software Defined Wide Area Network (SD-WAN): SD-WAN enhances network performance and efficiency by dynamically routing traffic across the best available paths. It provides greater flexibility, improved application performance, and reduced costs compared to traditional WAN solutions.
In contrast, SSE focuses on security services like Secure Web Gateway, Cloud Access Security Broker, and Data Loss Prevention, but does not include networking functions such as SD-WAN.

Two pillars of CASB are visibility and compliance. CASB stands for Cloud Access Security Broker, which is a solution that provides visibility and control over cloud services and web traffic, as well as data and threat protection for cloud users and devices. Visibility is the capability to identify all cloud services in use and assess their risk factors, such as security, auditability, business continuity, etc. Compliance is the capability to ensure that cloud services and data meet the regulatory standards and policies of the organization or industry, such as GDPR, HIPAA, PCI DSS, etc. Reference: What Is a Cloud Access Security Broker (CASB)? | MicrosoftCASB Guide: What are the 4 Pillars of CASB? - Security Service Edge
