A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Quotes from Members

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

Pros

"The benefits Fortinet FortiGate provides include easy connectivity, user-friendliness, scalability, and easy configuration management."

"The response from the technical support team has always been excellent."

"FortiGate firewalls are easy to manage through a user-friendly web interface. They also have advanced features like DDoS and DLP. However, I wouldn't recommend enabling all of these features on one device because it can cause performance issues."

"The performance is very good and the solution is simple to manage."

"Web filtering and two-factor authentication are great features."

"The simplicity of the configuration and the stability of the product are most valuable. The VPN concentrator is very useful."

"The most valuable features of Fortinet FortiGate are remote access, web filtering, and IPS."

"The IPS is good. It protect my network from attackers."

More Fortinet FortiGate pros

"The best feature is that Zscaler allows for a separation between cloud applications and URL filtering. For example, under the cloud application segment, I can bypass Microsoft Office 365 without the need to add URLs manually. It's one click, so that's handy."

"The product's most valuable feature is complete SSL inspection."

"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."

"The initial setup process is easy."

"The initial setup is straightforward and easy in comparison with other solutions."

Cons

"The solution’s stability could be improved because we sometimes faced some drops."

"The SD-WAN functionality is a bit overly complicated and not fully documented."

"To some degree, it's almost a question as to why some of this stuff isn't simpler. For example, for an AP deployment, while it's integrated, the number of steps that you have to go through in order to get the AP up, seems like a lot."

"The visibility of the network can be better. The GUI can be improved for better visibility of the network flow. Other solutions have better GUI in terms of network visibility."

"Fortinet should focus on enhancing the capabilities of FortiGate by consolidating its various products, such as FortiGate Cloud, FortiManager, and FortiAnalyzer."

"The UI/UX experience can be a little better."

"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."

"Difficult to add or define, and not that easy to configure and manage."

More Fortinet FortiGate cons

"There is always room for improvement."

"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."

"We encounter issues sharing IP addresses with other companies using the software."

"When it comes to scalability, the IPsec could be improved."

"They have given limited free access for a year. Instead, they should increase the file size and give limited free access for around two months. It will allow engineers to evaluate the product."

Pricing and Cost Advice

"The price is okay."

"Compared to other firewall products, it's a little cheaper in terms of pricing."

"If we have an older version, the support costs get quite high."

"FortiGate SWG is a cost-effective solution well-suited for organisations of all sizes."

"When comparing the price of Fortinet FortiGate SWG to other solutions it is expensive. The price could be better."

"It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."

"I pay €1,200 per year for the license along with Fortinet's 81E firewall appliance. I would rate this pricing as 3/5 stars, and I believe the price is reasonably similar to its competitors in the market, being somewhere in the middle."

"The licensing costs are very competitive."

More Fortinet FortiGate pricing and cost advice

"The product is not affordable for small and medium enterprises."

"Zscaler has so far been solely responsible for all the sales we have done with it, so it would be more suited than us to address any issues concerning the pricing."

"The software has become more expensive at present."

Sophos UTM vs. Fortinet FortiGate

I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
