For IT leaders

What IT leaders need to know before assigning this course

FortiGate outages, VPN instability, authentication failures, and routing issues can quickly become business-impacting incidents. This Fortinet NSE 6 - Network Security Support Engineer 7.6 training gives network security teams a structured path for troubleshooting FortiGate environments running FortiOS 7.6, with coverage across sessions and traffic flow, Security Fabric, central authentication and FSSO, security profiles, HA, IPsec VPNs, routing, BGP, OSPF, and resource monitoring.

IT Directors and Training Managers should plan for about 11 hours 45 minutes per learner, making this a practical assignment for network engineers, security engineers, and escalation support staff who already work with Fortinet infrastructure. For change management, this course is best used to standardize troubleshooting language and escalation steps across the team, especially where FortiGate firewalls support uptime, secure access, and audit-sensitive controls.

Team Impact

How this training helps your team succeed

IT teams complete this training to reduce the time it takes to isolate and resolve FortiGate issues before they affect users, applications, or compliance-sensitive traffic paths. The course maps to real support scenarios Fortinet teams face in production environments.

  • Faster firewall incident response: Teams build a common troubleshooting approach for FortiGate sessions, traffic flow, and security profile behavior.
  • More reliable secure access: Practitioners strengthen support for central authentication, FSSO, and IPsec VPN issues that can block users or remote sites.
  • Improved uptime planning: HA troubleshooting and FortiGate resource monitoring help teams identify problems that can lead to failover events or performance degradation.
  • Cleaner network escalation: Routing, BGP, and OSPF coverage helps network and security teams determine whether an outage is firewall, VPN, or routing related.

Whether you are already supporting Fortinet gear or are a senior engineer moving into a FortiOS 7.6 environment, this training ensures you can fix complex issues with confidence.

How much does a Fortinet NSE exam cost?

Most Fortinet NSE exams cost around $200, but different certifications have different exam requirements. This course prepares you for the NSE 6 - Network Security Support Engineer exam. If you want to earn your Fortinet Certified Solutions Specialist - Secure Networking certification, you’ll also need to pass the Fortinet NSE 7 - Enterprise Firewall Administrator, which costs $200. This brings the total certification costs to $400.

What jobs can I get with this Fortinet training?

If you already support Fortinet environments, this network security support engineer training can open doors to roles like network security engineer, firewall administrator, and network support engineer. Organizations that rely on FortiGate firewalls value professionals who understand FortiOS and can troubleshoot issues when networks are under pressure.

Is the NSE 6 - Network Security Support Engineer exam hard?

Yes. Fortinet exams are challenging because they test how FortiOS behaves in real networks. The NSE 6 focuses on troubleshooting: routing issues, log analysis, and CLI diagnostics. This course helps you practice the same workflows support engineers use when things break, not just find the settings in the GUI.

Is the Fortinet NSE 6 worth it?

If you work in (or want to work in) Fortinet-heavy environments, yes. The NSE 6 proves you can support and troubleshoot enterprise Fortinet deployments, not just tweak and manage them.
