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.

Stable product with valuable SSL inspection features
We use Zscaler Cloud IPS for threat protection, full SSL inspection, and data center scalability. It integrates with multiple products, including cloud firewalls, cloud sandboxing, Cloud Security Broker (CSB), and Data Loss Prevention (DLP). It helps us allow or block specific TCP or UDP ports…

Quotes from Members

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

Pros

"It is easy to use and performs very well."
"Fortinet FortiGate SWG's content is its most valuable feature."
"ROI is very high, it has hands-down the best price/performance/features ratio in the market."
"The product is easy to use and is stable. The SV1 functionality is a benefit."
"Overall, it's a great solution; the detection is great, the possibility to detect any anomaly under our match work is great, and we have a quick response."
"We use the filtering feature the most. It has filtering and inbuilt securities. We can create customized rules to define which users can access a particular type of site. We can create policies inside the firewall."
"I appreciate the ease of use, ease of setup, and the different abilities it has; I have been very pleased with it over SonicWall, the interface of Fortinet FortiGate is a lot easier to use and more robust, plus their VPN option is much better."
"This solution has a very friendly GUI and CLI as compared to other vendors."
"The initial setup process is easy."
"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 initial setup is straightforward and easy in comparison with other solutions."
"The product's most valuable feature is complete SSL inspection."
"Cloud IPS integration is seamless, and it uses a Zero Trust model, and it also simplifies overall user access management."
 

Cons

"Fortinet should focus on enhancing the capabilities of FortiGate by consolidating its various products, such as FortiGate Cloud, FortiManager, and FortiAnalyzer."
"I have used technical support and they could improve."
"Their software support needs improvement. I would prefer to have better support for bug fixes. Sometimes, we open a ticket, and it is very difficult to get a solution. Specifically, we are not at all happy with their support for load balancing."
"In our environment, we need multiple virtual firewalls to facilitate end users and customers. Fortinet doesn't provide that but they really should include that feature."
"FortGate's IPS reporting could be made better by giving more details regarding the source and destination of network traffic when it comes to the overview section. This would allow me to more easily follow the flow of traffic based on IP addresses, without having to integrate the IPS with other products that perform more sophisticated traffic analysis."
"I cannot say definitively about the return on investment with Fortinet FortiGate because I have always been in the technical field, but most of our clients are very happy since threats were stopped, generating confidence in the Fortinet brand among our clients."
"The solution has limited scalability. You have to change the hardware in order to ensure the solution can scale."
"The big license options have web filtering, IDS, and a lot of other things, but it's not like they are all good."
"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."
"We encounter issues sharing IP addresses with other companies using the software."
"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."
"When it comes to scalability, the IPsec could be improved."
"There is always room for improvement."
 

Pricing and Cost Advice

"The price range is quite acceptable and normal."
"FortiGate Next Generation Firewall is a very cheap solution."
"It's very competitive."
"Setup costs and pricing depends on many variables, but it's mostly affordable."
"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."
"We are currently evaluating a Palo Alto solution, and the pricing could be a reason for going for Palo Alto."
"I would rate the pricing a seven out of ten"
"There is no challenge in Fortinet FortiGate pricing."
"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."
"The product is not affordable for small and medium enterprises."

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…
