One of the key features of FortiOS is its advanced threat protection capabilities. It incorporates multiple security technologies, including firewall, antivirus, intrusion prevention system (IPS), and web filtering, to detect and block a wide range of threats. This ensures that organizations are protected against malware, ransomware, and other malicious activities. FortiOS also offers extensive network visibility, allowing organizations to monitor and analyze network traffic in real-time. This visibility enables businesses to identify potential security risks, detect anomalies, and take proactive measures to mitigate threats.
Additionally, FortiOS provides detailed reports and analytics, helping organizations gain insights into their network security posture. Centralized management is another crucial aspect of FortiOS. It allows businesses to manage and configure their security policies, devices, and users from a single console. This simplifies the management process and ensures consistent security across the entire network infrastructure.
Moreover, FortiOS supports integration with other Fortinet products, enabling seamless security orchestration and automation. FortiOS is designed to be scalable and flexible, making it suitable for organizations of all sizes. It offers a range of deployment options, including physical appliances, virtual machines, and cloud-based solutions. This flexibility allows businesses to choose the deployment model that best fits their requirements and easily scale their security infrastructure as their needs evolve.

| Director, IT Infrastructure Department at Zemen Bank S.C. | 4.5 | I have been using Fortinet FortiOS for nearly seven years for both internal and external firewalls. It excels in ease of use and seamless firmware upgrades. However, some versions face memory issues, necessitating better support to resolve these problems. |
| Senior Manager at ITX360 (Pvt) Ltd | 4.5 | I've used FortiOS for over ten years as a system integrator, valuing its user-friendly configuration and scalable features like web filtering and IPS. However, initial releases often have bugs, despite reasonable pricing and strong threat intelligence. |
| Senior Network & Security Engineer at a logistics company with 51-200 employees | 4.0 | I've worked with Fortinet FortiOS for six years, managing FortiGate via FortiWeb. Its valuable features include multi-tenancy and threat prevention. Improvements could include AI functionality and centralization. Compared to PAN-OS, it offers significant time and cost savings. |
| Network Administrator at a educational organization with 501-1,000 employees | 4.5 | I use FortiOS on FortiGate firewalls to manage wireless networks, benefiting from its user-friendly and reliable features. However, better CLI documentation would be helpful. Its reliability ensures a strong return on investment, negating frequent hardware replacements. |
| Technology Consultant at Netwiser | 4.5 | We use FortiOS for network security, benefiting from its IPS, web blocker, and application blocker features. However, real-time logging needs improvement. Despite Palo Alto's stability, Fortinet offers strong cost efficiency and compatibility, aligning with our system integrator partnership. |
| Manager IT Solutions Delivery at AL HIBA INFORMATION TECHNOLOGY SERVICES | 4.0 | I use Fortinet FortiOS mainly for site-to-site VPNs, reporting, and wireless capabilities. While it's well integrated within the Fortinet ecosystem, improvements could be made in third-party integration and consistent pricing across regions to avoid confusion. |
| Associate Director, IT at Khaitan & Co LLP | 3.5 | I use Fortinet FortiOS for load balancing and traffic filtering. Its significant features, like managing network sessions, are valuable, despite needing better reporting. I've experienced a 7% ROI, and it surpasses previous software solutions in stability and manageability. |
