The Digital Experience Monitor (DEM) feature in FortiSASE is a specialized monitoring tool integrated into the SASE cloud to ensure optimal application performance and user satisfaction.2

Purpose and Visibility: DEM is designed to provide end-to-end network visibility by monitoring the health and performance of the connections between the global FortiSASE security Points of Presence (PoPs) and specific SaaS applications (such as Microsoft 365, WebEx, or Dropbox).

Performance Metrics: It identifies and helps troubleshoot issues related to latency, jitter, and packet loss. By leveraging vantage points within the SASE infrastructure, administrators can determine if a performance bottleneck resides within the local network, the SASE backbone, or the SaaS provider's environment.

Integration: This feature is often powered by FortiMonitor, allowing for synthetic transaction monitoring (STM) to simulate user interactions and proactively spot performance issues before they impact the hybrid workforce.

Operational Efficiency: By providing comprehensive insights across users and PoPs, DEM reduces the time required to resolve "slowness" complaints, which are common in remote work scenarios.

Comparison of Other Features:

Option A: While FortiSASE monitors PoP health, DEM's primary value is the end-to-end path to the application.

Option B: Compliance checks are a function of Endpoint Profiles and ZTNA tagging rules, not the monitoring dashboard.

Option D: Vulnerability management is handled by the Vulnerability Scan feature within the managed FortiClient settings.
