What is our primary use case?
Fortinet FortiGate is our primary security solution for network communication. It enforces segregation between the IT and OT networks. All communication, integrations, and other traffic between IT and OT must pass through the FortiGate, which inspects and controls it.
FortiGate also serves as our VPN concentrator. Both internal users and partners connect their VPNs to FortiGate. We manage the entire VPN process, including access control and security policies.
All web traffic within the organization flows through the FortiGate for inspection and security controls. We leverage FortiGate's UTM capabilities, including web filtering, intrusion prevention, and application control.
While we have several websites running behind FortiGate, they are primarily static content sites with limited business activity. Therefore, we utilize the basic WAF functionality within FortiGate instead of a dedicated WAF device. This approach has proven effective for our needs due to the low volume of transactions and sensitive data on these websites.
FortiGate also manages communication between our internal IT units. With five units in operation, efficient inter-unit communication is critical. FortiGate ensures secure and controlled data exchange between these units.
How has it helped my organization?
FortiGate provides us with both visibility and segmentation for our industrial devices. This allows us to achieve good segmentation and also gain a clear view of the assets that reside behind them. Now, if I need to find a specific asset within our industrial environment, I can simply access Fortinet and check the assets listed there. Additionally, FortiGate utilizes sensing technology that identifies the type of each device, further enhancing our overall visibility.
FortiGate helps a lot to reduce the risk of cyberattacks that could disrupt our production.
FortiGate enables centralized management of our organization's network and security operations, providing comprehensive visibility into our environment for proactive threat detection and mitigation.
The effectiveness of our response to a production disruption depends on the affected environment. Some environments have sufficient redundancy to continue operating without the system, while others require immediate intervention. To address this variability, we utilize a strategically deployed FortiGate across all environments. This firewall enforces pre-defined rules to manage traffic and data flow effectively, ensuring that disruptions are minimized and operations continue smoothly.
FortiGate provides us with actionable data, enabling us to make informed decisions. The visibility it grants into the devices operating within our environment empowers us to take timely action and safeguard them.
All our OT traffic traversing to and from our IT environment passes through our Fortinet FortiGate firewall, which helps to reduce our operational expenses.
The security fabric helps reduce our mean time to remediation.
Fortinet has helped us take a more serious approach to cybersecurity.
What is most valuable?
The Intrusion Prevention System and the web filtering are both working well. The Deep Packet Inspection is also functioning properly, allowing us to see all network traffic, including encrypted data. I find the DPI to be a valuable and user-friendly feature. Additionally, the logs are clear and easy to understand. Having worked with Cisco and Check Point in the past, I can confidently say that these logs are on par with those of other leading security solutions. They greatly aid in troubleshooting, investigations, and general network monitoring. Overall, I am impressed with this solution's web filtering capabilities and robust IPS functionality. It is both easy to manage and deploy, making it a valuable tool for our network security.
What needs improvement?
While FortiGate offers a wide range of security features, I sometimes feel that the platform could benefit from more extensive improvements. Given the multitude of functions it provides, I wonder if the developers have enough time to adequately refine each aspect. However, for our specific needs, FortiGate currently performs adequately.
The debugging and troubleshooting has room for improvement.
I would like to see greater integration with third-party solutions. For instance, one example would be integrating Endpoint Protection with FortiGate, such that if an issue arises with Endpoint Protection, an action could be automatically triggered on FortiGate.
I am concerned about Fortinet's ability to help us meet regulatory compliance because its optimal functionality requires deploying all solutions within the mesh as Fortinet products. This raises questions about the compatibility and integration of non-Fortinet technologies within the Fortinet Security Fabric.

Although we currently don't use any Fortinet devices designed for extreme environments, we are planning to test a few Fortinet switches in such conditions. This initial experiment aims to assess their performance and suitability for our harsh environment. If the switches perform well, we may consider switching our current supplier. While we don't frequently change our OT networks, prioritizing long-term stability has been our main objective, and we've achieved that so far. However, since Fortinet is our network supplier, testing their switches and confirming their reliability is a prudent step for when we need to update our switches.
Potential users should understand their needs before purchasing the solution.
