Extend long-term SD-WAN service coverage for FortiGate-4201F-DC with a 5-year bundle designed for demanding network environments. This service supports underlay monitoring and application monitoring, giving operations teams the visibility they need to understand link behavior, application performance, and traffic conditions across complex WAN deployments. For large-scale infrastructure, sustained insight matters. When multiple circuits, sites, and application classes are in play, the ability to monitor the underlay and application layer helps teams identify degradation before it becomes disruption. That translates into faster troubleshooting, better routing decisions, and more consistent performance for business-critical traffic. The 5-year term is well suited to organizations that want to lock in service continuity and reduce the friction of frequent renewals. It also supports the economics of premium edge infrastructure: fewer gaps in coverage, more predictable operations, and a stronger foundation for SD-WAN policy enforcement over time.
