Fortinet FortiGuard 1-Year FortiGate-400D Enterprise L3 | Firewall Security

Extend the value of your FortiGate-400D with 1 year of FortiGuard Enterprise L3 service. This subscription keeps critical security intelligence current so your firewall can continue enforcing policies against evolving threats without interruption. For teams responsible for uptime, compliance, and controlled access, timely signature and service updates matter as much as the appliance itself. Enterprise L3 coverage is built for organizations that need dependable protection and predictable renewal planning. It helps maintain the security posture of a deployed FortiGate-400D by keeping Fortinet threat intelligence and service entitlements active across the subscription term. That means fewer gaps in coverage, less operational risk, and a cleaner path for standardizing firewall maintenance across sites. This service is a practical fit for environments where the firewall is already part of the production security stack and continuity matters. It supports the discipline of keeping defenses current, which is often the difference between a managed perimeter and a stale one. For procurement and infrastructure teams, it also simplifies budgeting by turning ongoing protection into a defined annual line item.
