At Catchpoint, our mission is to provide customers with actionable data that will help them reduce MTTR and maintain a positive digital experience. We measure "from where the users are" to ensure the data reflects real end-user experience. As someone that's part of the Catchpoint on-call chain, this is extremely important to me.

Amazon WorkSpaces enables you to provision virtual, cloud-based Microsoft Windows or Amazon Linux desktops for users. WorkSpaces eliminates the need to procure and deploy hardware or install complex software. You can quickly add or remove users as your needs change. Users can access their virtual desktops from multiple devices or web browsers.
