Frequently Asked Questions

You will learn how to design, implement, and operate secure OT environments using Fortinet technologies across asset management, network access, segmentation, protection, monitoring, and risk management.

The course takes you through the major security considerations involved in protecting operational technology and industrial environments. You will learn how to:

  • Apply the Purdue model to OT security
  • Identify and manage OT assets
  • Implement segmentation and microsegmentation
  • Control network access and authentication
  • Protect industrial network traffic
  • Centralize logging and reporting
  • Monitor and analyze security events
  • Assess and manage OT security risks

The training uses FortiGate, FortiNAC, FortiAnalyzer, and FortiSIEM to show how these capabilities work together within an OT security architecture.

Pro Tip: Think beyond individual security products during this course. The key skill is understanding how multiple controls work together to protect an OT environment without unnecessarily disrupting operational processes.

This course is ideal if you are responsible for designing, implementing, or securing operational technology infrastructure using Fortinet solutions.

You should consider this course if you work in roles such as:

  • OT Security Architect
  • Cybersecurity Architect
  • Industrial Network Engineer
  • Network Security Engineer
  • OT/ICS Security Engineer
  • Critical Infrastructure Security Professional
  • Security Consultant

The course is particularly relevant if your responsibilities extend beyond administering individual security products and into designing an integrated security architecture for industrial or operational environments.

Pro Tip: This is architecture-oriented training. You will gain the most value if you already understand network security and want to apply that knowledge specifically to OT and industrial environments.

You should already understand FortiOS administration, with FortiAnalyzer knowledge also recommended before attending.

The course requires an understanding of the topics covered in FortiOS Administrator, or equivalent practical experience. Familiarity with the topics covered in FortiAnalyzer Analyst is also recommended.

Fortinet additionally recommends substantial hands-on experience for professionals pursuing the associated certification. For the current OT Security Architect exam, Fortinet recommends a minimum of two years of experience designing, implementing, and integrating Fortinet solutions within OT infrastructure.

Pro Tip: If your Fortinet experience is primarily theoretical, build hands-on FortiGate and FortiAnalyzer experience first. This course assumes you are ready to apply those technologies to more complex OT architecture scenarios.

You will learn how FortiGate, FortiNAC, FortiAnalyzer, and FortiSIEM work together to secure and monitor OT environments.

Each technology supports a different part of the OT security architecture:

  • FortiGate for network security, industrial protocol inspection, segmentation, and protection
  • FortiNAC for device visibility, identification, and network access control
  • FortiAnalyzer for centralized logging, reporting, and security analysis
  • FortiSIEM for security event monitoring and real-time analysis

The current course uses FortiOS 7.6, FortiAnalyzer 7.6, and FortiSIEM 7.4, while Fortinet’s current exam also references FortiNAC 7.6.

Pro Tip: Focus on understanding the role each product plays within the overall architecture. OT security design requires integrating visibility, access control, segmentation, protection, and monitoring rather than relying on a single security control.

The course teaches you how to use segmentation and microsegmentation to control communications between OT assets and reduce the potential impact of security incidents.

Segmentation is particularly important in OT environments because industrial systems often contain devices with different functions, trust levels, operational requirements, and security capabilities.

The course covers securing OT infrastructure using the Purdue model, implementing segmentation and microsegmentation, authenticating users, and securing OT network traffic through FortiGate.

These capabilities align directly with the current OT Security Architect exam, which assesses network segmentation schemas, access authentication, industrial protocol inspection, and virtual patching.

Pro Tip: Pay attention to the operational impact of segmentation decisions. In OT, an effective security architecture must strengthen isolation while preserving the communications required for industrial processes to operate reliably.

Yes. The course covers centralized logging, real-time security monitoring, reporting, and OT risk assessment as part of the overall security architecture.

You will learn how FortiAnalyzer can centralize logging and reporting and how FortiAnalyzer and FortiSIEM can support real-time security event analysis. Risk assessment is also a dedicated part of the course curriculum.

These skills are reflected in Fortinet’s current exam objectives, which include:

  • Creating FortiAnalyzer event handlers
  • Performing risk assessment and management
  • Analyzing FortiAnalyzer security reports

Pro Tip: Do not treat monitoring as the final step after security controls are deployed. Use monitoring and risk assessment continuously to identify where your OT security architecture needs to change.

Yes. OT Security Architect is Fortinet’s recommended training for the current Industry Certification in OT Security, but the certification pathway changed in July 2026.

This is important because the certification information currently displayed on the Trainocate course page references the previous NSE 6 – OT Security Architect / FCSS Secure Networking structure.

Fortinet officially retired that NSE 6 designation on 15 July 2026 and replaced it with the Industry Certification – OT Security pathway.

Under the current structure, you must hold:

  • NSE 4 FortiOS certification
  • An NSE 5 or NSE 6 certification
  • An NSE 7 certification in the same track as your NSE 5 or NSE 6
  • Pass the Fortinet NSE I – OT Security Architect proctored exam within two years of your last prerequisite exam

The certification validates your ability to design, deploy, and monitor advanced Fortinet security solutions for OT environments.

Pro Tip: If certification is your objective, use this course for OT-specific technical preparation but map your existing NSE credentials against Fortinet’s new post-July 2026 requirements before scheduling the exam.

The course helps you progress from general network security into the specialized field of securing industrial, operational technology, and critical infrastructure environments.

The skills developed are relevant to roles such as:

  • OT Security Architect
  • OT/ICS Security Engineer
  • Industrial Cybersecurity Engineer
  • Network Security Architect
  • Critical Infrastructure Security Specialist
  • OT Security Consultant

The course is particularly valuable for professionals who need to understand both traditional cybersecurity controls and the operational requirements of industrial environments. Fortinet’s current Industry Certification in OT Security specifically targets cybersecurity professionals who need expertise designing and implementing OT infrastructure security using Fortinet technologies.

Pro Tip: If you already have strong enterprise network security skills, use OT training to build expertise in industrial protocols, asset visibility, segmentation, operational risk, and availability requirements. These are some of the areas that distinguish OT security from conventional IT security.
