Netskope
The Netskope App provides visibility into the security posture of your applications and helps you determine the overall usage of software and SaaS applications.
Netskope is a Cloud Access Security Broker (CASB) hosted in the cloud. The Netskope product is primarily used for enforcing security policies for cloud-based resources, such as Box and Microsoft Office 365. Customers purchase a CASB to address cloud service risks, enforce security policies, and comply with regulations, even when cloud services are beyond their perimeter and out of their direct control.
Log Types
The Netskope App provides a collector source for pulling all the events and alerts from Netskope in real-time via API calls and ingests them into the Sumo Logic platform through our Hosted collector.
For more information on Netskope, refer to the Netskope documentation.
Collect Logs for Netskope
To collect logs from the Netskope platform, use the new Cloud to Cloud Integration for Netskope to create the source and use the same source category while installing the app. You can view the Netskope legacy collection method here.

Installing the Netskope App
This section demonstrates how to install the Netskope App, and provides examples and descriptions for each of the dashboards. The Netskope App has the following components:
- Application Usage: Insights into application usage; specifically by devices, users, users and traffic patterns.
- Security Alerts: Visibility into Netskope security alerts and violations and the ability to identify effects of a breach.
To install the Netskope App:
Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.
- From the App Catalog, search for and select the app.
- Select the version of the service you're using and click Add to Library.
Version selection is applicable only to a few apps currently. For more information, see Installing the Apps from the Library.
- To install the app, complete the following fields.
- App Name. You can retain the existing name, or enter a name of your choice for the app.
- Data Source. Select either of these options for the data source.
- Choose Source Category, and select a source category from the list.
- Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. Example: (
_sourceCategory=MyCategory).
- Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
- Click Add to Library.
Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization.
Panels will start to fill automatically. It's important to note that each panel slowly fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but with a bit of time, you'll see full graphs and maps.
