Going well beyond the concept of client health (that is, whether a device is functioning or not), SLEs measure actual user experiences in real time, based on continuously delivered (and actionable) telemetry. SLEs are maintained using applied data science and machine learning to understand the actual end-user experience on the network.
SLEs identify root causes of suboptimal application experiences in just a few clicks and proactively isolate needle-in-a-haystack problems that may occur anywhere in the WAN.
