Yati Gharat - PeerSpot reviewer
Chief Technology Officer at Litmus
Unified security management has simplified data center protection and optimized branch connectivity
In my opinion, a potential area of improvement for Fortinet FortiGate is that while it has a pretty good dashboard, which is not an issue as such, when we talk about hardware parameters, sometimes the hardware gets pretty heated up. Given the amount of traffic going through it, that is fine. However, the heat of the hardware has to be looked into. Fortinet FortiGate firewall is good, but other products like the switching part and all that fabric, in handling very audio-video traffic, sometimes it struggles on the switching part, but on the routing part, it is fine. On the firewall part, it is good; there is no issue as such up till now. Additionally, I suggest that Fortinet can add software which is in a controlled way, particularly regarding AI and ML. It should not happen that the AI/ML takes certain decisions which are not beneficial for the organization. The control should remain with the team members who are responsible for configuring this firewall.

I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

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

Pros

"The security features are valuable, particularly the ransomware attack protection features. Fortinet FortiGate provides excellent security against ransomware attacks."
"It's user-friendly and easy to operate."
"Fortinet scores very high against security threats when you compare it with Check Point and Palo Alto."
"I am satisfied with the technical support from Fortinet FortiGate."
"The initial setup was very easy and straightforward."
"Fortinet's scalability and stability are fine because I have three units across India, and none have gone down so far."
"It has been very stable and reliable."
"The IPS is good. It protect my network from attackers."
"The cost is very low."
"The solution can scale well."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
 

Cons

"The user interface could be improved."
"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."
"They should add a feature for detailed reporting."
"I have contacted the support from Fortinet FortiGate IPS. The service was good but the speed could be better."
"We were not able to build a full-mesh VPN; however, I am not sure if this was the fault of Fortinet FortiGate."
"The AI with Fortinet FortiGate is not very well integrated on their devices, and their cloud infrastructure is not as good as Cisco's."
"We had some issues in the beginning while setting it up, but after doing the firmware update, it is working fine."
"A couple of things I've seen that need improvement, especially in terms of a hard coding. The driver-level active moment really is out-of-the-box and we have to have contact the customer support and sometimes it is difficult to resolve."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."
"Pricing is lower than Cisco."
"Their licensing costs are annual. The UTM feature license along with their support is called FortiCare. We include that as a part of the annual maintenance cost. Palo Alto or Juniper also have an annual subscription charge for UTM. Price, of course, can always be more competitive, but it is not the most expensive product. The price-performance ratio is quite high for FortiGate."
"The price is highly competitive when compared to other brands that offer similar functionality."
"Its price could be better."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"It's an expensive solution."
"Fortinet FortiGate gives you most of the features in one license."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."

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…
