# 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
