Yati Gharat - PeerSpot reviewer

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.

Complements any firewall
The core processors are there and it's able to generate reports for that. It also complements any kind of firewall. For example, if an end user is using Palo Alto as a firewall, they'd need another layer of firewall like the S-Series that will protect internal servers. It's something that complements any firewall in the market.

Quotes from Members

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

Pros

"With FortiClient, you can easily connect when you are home, check out what you want to do, and connect to your network when you are not at work. You can switch on servers and you can check what is wrong."
"Fortinet has a product that can cater to any area of the security market."
"I like that you are able to manage FortiGate from the FortiManager to create a more centralized environment."
"Fortinet FortiGate is one of the best firewalls in the market currently, with a lot of next generation firewall features embedded into it, including SD WAN, which is one of the best services for traffic steering, managing packet log jitter and latency for any applications, making it unbeatable in terms of pricing compared to other firewalls."
"Customer Service: They're good. Technical Support: They're very good."
"Fortinet FortiGate is easy to use."
"The solution is stable; it doesn't have any issues with bugs and glitches, it doesn't crash or freeze, and it's very reliable."
"The solution from Fortinet FortiGate is very good, and our experience has been very good."
"Setup is straightforward with the same reliability and scalability as the firewall series."
 

Cons

"I would like to see improvements in Fortinet FortiGate regarding the active-active scenario. The active-active scenario is supported but not recommended, whereas other vendors are implementing active-active without issues. Perhaps in the future, we could effectively use both firewalls to increase the throughput. If there are two boxes, they both should be able to work."
"It takes a long time to install the solution."
"They need faster serviceability and more security features."
"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."
"In my opinion, Fortinet FortiGate could be improved by making the appliance smaller than what we have here, as it is pretty big."
"FortiGate's logging and reporting could be improved. I would also like to see Fortinet add a guest management portal."
"The tool is expensive for small businesses, making it an area where the tool can improve the product by making it available at a cheaper rate."
"Support could be improved."
"Lack of tools to help educate end users"
 

Pricing and Cost Advice

"The price range is quite acceptable and normal."
"By default, they give SD-WAN along with the firewall. They don't have separate licensing for the SD-WAN functionality. However, they have security licenses that are sold separately on a subscription basis. Customers can consume these security features to protect their users from internet traffic."
"There is only a standard license cost to use the solution."
"FortiGate Next Generation Firewall costs our company around $12000 per year."
"Fortinet bundles FortiGate with other products and because of this, the price is a little expensive to some SMB enterprises."
"Other firewalls are more expensive than Fortinet FortiGate, such as the Azure firewall."
"The price, in comparison to other products is very cheap."
"The solution's pricing is competitive."

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…
