# Application Categories An *application category* is a user-defined bundle of applications with similar traffic characteristics, such as Voice or Google Workspace. Each application category includes multiple applications within it, along with a single set of quality thresholds for loss, latency, and jitter that apply to all traffic for a given application category. You can define your WAN Insights own customized application categories and quality thresholds as described in [Adding Business-Critical Applications to WAN Insights](https://docs.thousandeyes.com/product-documentation/wan-insights/tasks/custom-application-categories). Note that WAN Insights application categories are defined in vManage as an *application list*. Use care to avoid configuring the same application in multiple classes in vManage. ## Out-of-the-box Application Categories WAN Insights includes the following default application categories out-of-the-box: * Office365 * Voice * Salesforce * Google Workplace * Go To Meeting * Webex The quality of service (QoS) thresholds for each default application category are shown below. The units are expressed as a fraction for loss, and milliseconds for latency and jitter. * **Office 365**: Loss 0.03, Latency 300, Jitter 300 * **Voice**: Loss 0.03, Latency 300, Jitter 50 * **Salesforce**: Loss 0.03, Latency 300, Jitter 300 * **Google Workspace**: Loss 0.03, Latency 300, Jitter 300 * **Webex**: Loss 0.03, Latency 300, Jitter 50 * **GoTo Meeting**: Loss 0.01, Latency 300, Jitter 100 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
