Unified security has protected diverse environments and supports consistent policies everywhere
I would say 8 out of 10 regarding the stability of Fortinet FortiGate. It requires a lot of bug fixing and what I understand, Fortinet is fast enough to provide bug fixes and patches, but usually I suggest Fortinet should do thorough testing of their releases and software releases and once probably they can reduce the frequency of new releases but make it stable. That's what my recommendation is. As far as the core objective of Fortinet FortiGate is concerned, I think they are meeting the targets but I guess for rolling out new features and new updates, they are doing a bit of hurry just to cope with the market dynamics. But possibly, I understand that they are compromising on the quality of the software and stability. So over there they have to improve. Rest of the aspects, I guess they are doing pretty good. We are happy. Regarding my experience with Fortinet FortiGate in comparison to maybe some other vendors such as CyberArk, Fortinet is in the top three and they give a lot of competition to their nearest peers in the market. But I guess Fortinet is really struggling in software-defined LAN, Wi-Fi, and FortiSwitches space. So they have to make their products more affordable in Forti-switching and Forti-WiFi space. They are not able to compete effectively with the nearest competitor HP Enterprise and HP Aruba.

Quotes from Members

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

Pros

"Load Sharing VDOM Security Profiles Vulnerability Assessment"
"The product has the most valuable configuration, offloading, and security features."
"Consolidated our network environment at all locations, but mainly at our datacenter."
"The solution has a variety of excellent features."
"In a scenario where FortiGate Next Generation Firewall (NGFW) notably enhanced my customer's network performance, we discussed many points."
"This solution works well on a daily basis, detecting various types of malicious traffic."
"Fortinet FortiGate has many functions, and it is one of the best next-generation firewalls with an affordable cost than other vendors."
"Fortinet FortiGate has a very stable Linux-based operating system that is easy to use."
"The initial setup process is easy."
"Cloud IPS integration is seamless, and it uses a Zero Trust model, and it also simplifies overall user access management."
"The initial setup is straightforward and easy in comparison with other solutions."
"The product's most valuable feature is complete SSL inspection."
"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."
 

Cons

"The solution could maybe use more integration with artificial intelligence to be more proactive."
"There are too many updates coming for VPN, and the VPN keeps disconnecting frequently, which I find problematic. It does what it's supposed to do, but I practically face reconnection issues with the VPN."
"Fortinet FortiGate IPS could improve the VPN. There are times it is slow."
"FortiGate Next Generation Firewall's performance and threat intelligence could be improved."
"Whitelisting could be better."
"They can probably improve the reporting feature. Reporting and report alerting are the main key features of this solution. They can always find ways to improve these."
"Technical support is a little slow and needs to be improved."
"The ease of use could be improved."
"There is always room for improvement."
"When it comes to scalability, the IPsec could be improved."
"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."
"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

"Its price could be better."
"We have the full license that included all of the features and support."
"Fortinet FortiGate is reasonably priced."
"The price is fair compared to the other competitors."
"I think the price of Fortinet FortiGate is very reasonable."
"Licensing for Fortinet FortiGate is on a yearly basis. Pricing for it is a bit high. It could be cheaper."
"The solution could be better priced."
"In my opinion, the pricing of the product is reasonable."
"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 product is not affordable for small and medium enterprises."
"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…
