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

"Fortinet FortiGate has SD-WAN, FortiView, antivirus, sandbox, and IPS, which are generally well-known features."
"It offers web filtering capabilities at a more affordable price compared to other solutions like PSMs or NETGEAR."
"FortiGate Secure SD-WAN includes best-of-breed next-generation firewall (NGFW) security, SD-WAN, advanced routing, and WAN optimization capabilities, delivering a security-driven networking WAN edge transformation in a unified offering."
"There’s something magical about the way the flavors blend together, creating a dish that is both comforting and exciting."
"Reliability and performance, those are key factors."
"Fortinet FortiGate offer a good value for money solution"
"Buy FortiGate for a hassle free network management and excellent ROI."
"We have heard that other companies are being attacked, but we are not since we installed FortiGate."
"The cost is very low."
"This is a capable appliance and the standard features work well for us."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
 

Cons

"Fortinet already improved FortiGate, but in the current market, many brands of security devices have improved together. Fortinet still needs to catch up with market standards. Fortinet is lacking in features in comparison to competitors."
"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."
"Scalability is one of the disadvantages. When it comes to scalability, you have to actually change the box. If you want to upgrade it, you need to actually change the existing box and probably you take the system off to other sites."
"FortiGate is really good. We have been using it for quite some time. Initially, when we started off, we had around 70 plus devices of FortiGate, but then Check Point and Palo Alto took over the place. From the product perspective, there are no issues, but from the account perspective, we have had issues. Fortinet's presence in our company is very less. I don't see any Fortinet account managers talking to us, and that presence has diluted in the last two and a half or three years. We have close to 1,500 firewalls. Out of these, 60% of firewalls are from Palo Alto, and a few firewalls are from Check Point. FortiGate firewalls are very less now. It is not because of the product; it is because of the relationship. I don't think they had a good relationship with us, and there was some kind of disconnect for a very long time. The relationship between their accounts team and my leadership team seems to be the reason for phasing out FortiGate."
"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."
"Someone without certification and experience with other firewalls might find it a bit more challenging to grasp the FortiGate format and its platform layout."
"There are SD-WAN network monitoring, SD-WAN features, Industrial Databases, Internet of Things, Detection, etc., however, we do have not licenses for those features. We thought that if you bought a product, you should have all of the features it offers. Why should you need to make so many extra purchases to enable features? They should have one price for the entire offering."
"I mostly do administration, and I found Cisco to be the hardest major firewall manufacturer to deal with, with Fortinet FortiGate being the second hardest for me."
"The product has some scalability and data management issues where improvements are required."
"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."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"Sometimes it reboots when you least expect it, and that's the main issue."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
 

Pricing and Cost Advice

"I think the price of Fortinet FortiGate is very reasonable."
"The pricing is better compared to other solutions like Check Point, Arista, or Cisco."
"I would rate the pricing a six out of ten, where one is cheap and ten is expensive."
"No comment."
"If the customer is looking for SD-WAN, it comes free with FortiGate."
"Fortinet prices are around $600 for the small 40F model, and for licenses, the simplest option is about $300 for a year. They sell licenses that can last for 1, 2, 3, or 5 years."
"Pricing is good. They offer a lot of things, the most important is the support. Every time you upgrade your license, you also get insurance for the equipment. If you have any problem with equipment, they send in new equipment."
"The pricing depends on the FortiGate model we are using, ranging from $3,000 to $20,000 US dollars."
"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…
