IP Network Security Specialist at MTN Ghana

Process-Level CPU Visibility: Introduce detailed CPU-usage metrics per subsystem (e.g., IPS engine, logging) so administrators can quickly identify and address performance spikes.

Analytics with FortiAnalyzer. Being able to pull in logs not just from our FortiGates but from all our other firewalls and then get them in one view has been a game changer. Whether I’m building an executive dashboard or doing a deep dive forensics session, I get everything I need without navigating consoles.Straightforward Application Control. FortiGate spots and blocks unwanted apps (eq. like BitTorrent or streaming services) with accuracy. Segmentation with VDOMs. We’ve carved our data center into four logical ‘mini-firewalls’ enterprise, core, billing, and WAF—all on one box. Each has its own rules and logs, and any traffic between them still gets inspected. It’s like having multiple appliances without the extra hardware. Always-Up-to-Date Threat Feeds. Daily signature updates and AI-driven threat sensing mean we’re blocking the latest vulnerabilities almost as soon as they’re announced.

Single-pane management has simplified firewall control and has improved risk mitigation

I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The impact of SD-WAN on my network performance is clear, and if we speak about Fortinet Unified SASE, it is effective for me."

"We have several sites spread geographically across Latin America and Asia that use FortiGate, and some of them are unable to support cloud services so we have deployed it on-premise in order to provide ourselves with a fast and secure network."

"It is quite easy to handle."

"This solution works well on a daily basis, detecting various types of malicious traffic."

"It has upscaled our security posture, especially regarding external connectivity, because any access or connection from the company has to go through the Fortinet FortiGate firewall."

"The best features of Fortinet FortiGate include good functionality, though the licensing cost is a bit higher; their response time and throughput are very good advantages."

"SD-WAN has had a positive impact by reducing the operational costs in terms of headcount and management."

"The technical support in our region is excellent."

More Fortinet FortiGate pros

"The solution constantly adds features that are useful and user-friendly such as the ability to tweak firewalls through the CLI."

"In my opinion, Fortinet FortiOS provides significant benefits to users, such as saving time, saving money, and streamlining workflow processes."

"The firewall options in FortiOS allow us to open up access to our vendors for EDI and all its features."

"The most valuable feature of Fortinet FortiOS network segregation, UTM, and antivirus, freight management protection, such as DDoS. Additionally, the CLI and the GUI are easy to use. The architecture makes sense, and the command in the CLI are organized well. They have quite a lot of features are easy to use, and are user-friendly. Any novice can use Fortinet FortiOS without an issue."

"There are many useful features, such as web security and advanced threat detection."

"Security and authentication are the most valuable aspects of the product."

"Fortinet FortiOS is highly stable."

"So far, I'm very satisfied with this device."

More Fortinet FortiOS pros

"The app inspection is very helpful for network security."

"The stability of Palo Alto Networks CN-Series is excellent."

Cons

"Application management can be improved."

"There are some license issues. Not every feature must have a separate license. There must be some of kind synergy between the license so we don't have to pay for every individual license that we would like to have."

"The price could be improved."

"Usually, we sell the bundle with the UTM or threat management piece with IPS, IDS. Other providers, such as Palo Alto, are ahead in terms of safe functionality. So, for me, delivering truly safe service is probably something that still needs to be improved."

"With FortiGate, the main complaint that I have heard is about the technical support."

"There is room for improvement in pricing."

"The learning curve is a bit higher."

"I have an issue with NAT only, in that I can't allow traffic from outside to inside using a NAT pool."

More Fortinet FortiGate cons

"For monitoring purposes, we don't have any option to monitor the ISP link."

"I would like to see a drop in the license fees because it is a rather expensive program."

"Their technical support needs improvement."

"FortiOS's bandwidth and interface could be improved."

"The reporting and monitoring could improve, they have a lot of limitations. The monitoring is not easy compared to the other firewall."

"In the future I would like to see more user-friendly dashboards and a drop in the price."

"The technical support is good. However, during the holidays they can get a little slow to respond."

"I would like to see fewer bugs. If you use the box with its basic features, the solution is straightforward and stable, but you can run into bugs when using newer features or in more complex use cases. They included a DNS filter as a new feature, and I had issues that required raising a ticket with customer support."

More Fortinet FortiOS cons

"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."

"I'd like to see more IOPs features."

Pricing and Cost Advice

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."

"It's an expensive solution"

"Its price could be better."

"The price is really low. It's cheap in comparison to the cost of Cisco or CheckPoint, for example."

"The price is okay, so far so good."

"The solution is cheap."

"The pricing for this solution is good."

"I give the pricing of the solution a six out of ten."

More Fortinet FortiGate pricing and cost advice

"I am on a two-year contract and I pay annually for Fortinet FortiOS."

"The solution could have a better licensing model. It's a bit more expensive than other solutions. The annual subscription is very pricy in Fortinet. The cost could be reduced."

"The scalability of Fortinet FortiOS is good. However, central management is intuitive for the end-users. We had a lot of questions about central management, and sometimes they didn't use it and did their firewall management directly on FortiGate instead of using Fortinet FortiOS."

"The cost is around $40,000."

"It is not cheap; it is also not expensive. It is somewhere in the middle."

"The licensing for FortiOS is good, with a security license included when we update the main license."

"It would be better if it were cheaper. We have the firewall in our office, and the license is expiring in 20 to 25 days. We got a quote for almost 80,000 Pakistani Rupees, which is a little costly."

"Pricing for the tool can vary. Sometimes, aggressive pricing is offered at the start, but later, as subscriptions and expansions are needed, the costs can increase, and customers may have to pay whatever is required."
