A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

One of the best tools for the prevention of evasive threats
There is a feature called granular application controls, which I liked. Instead of relying on ports and IP addresses, they use AMP ID. This kind of solution is very good. Another valuable feature is the prevention of evasive threats, which is one of the best tools I've encountered. SSL decryption and app ID-based SSL decryption are also impressive, along with the integration with user ID. Identity-based policies ensuring only authorized users can access specific resources are excellent features. Normally, there is something called SIM or SCIM in IDA IDM, but this feature is provided on the box, which is exemplary.

Thorough with all-in-one security functions and good affordability
The all-in-one gateway security functions and the ability to install it on generic equipment stand out. The centralized management console is great. I can template my installations and configurations. My ability to monetize it as a gateway security appliance to offer enhanced service offerings allows me to increase our price point. I provide it as a managed device to many of our clients. I take on the initial costs and charge them a monthly fee. They have threat detection.

Quotes from Members

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

Pros

"In a scenario where FortiGate Next Generation Firewall (NGFW) notably enhanced my customer's network performance, we discussed many points."
"I like that you are able to manage FortiGate from the FortiManager to create a more centralized environment."
"It's great for capturing the traffic and troubleshooting it."
"From the firewall perspective, the rules and policies are very sufficient and easy to use."
"ROI is exceptionally good."
"The user interface (UI) is very, very good."
"The security features are valuable, particularly the ransomware attack protection features. Fortinet FortiGate provides excellent security against ransomware attacks."
"One of the best features of Fortinet FortiGate is that it's a very powerful equipment that gives many security features in a single box with good performance, and the user interface is friendly to use and configure."
"Palo Alto has better and finer controls than, say, Cisco or Check Point."
"Palo Alto's App-ID is what differentiates it from other competitors."
"I have found the threat profile feature valuable."
"The application ID on the Palo Alto Networks K2-Series is able to understand the application traffic, and WildFire is also good."
"The solution offers effective security features such as HIDS (Host-based Intrusion Detection System) in global products."
"It's easy to configure."
"The scalability of the product is quite high."
"Overall, this is a very simple and very effective firewall, and I am satisfied with it."
"The product’s most valuable features are endpoint protection management, load balancing, and connectivity with Active Directory."
"Web filtering is very reliable."
"It is not attached to an appliance, meaning if you get a good PC/server, then you can already run a firewall."
"​It is very easy to deploy and monitor. ​"
"They have a command center that makes it easy to log into and see all of your appliances nationwide."
"The interface is very good."
"The initial setup is very easy."
"None of my clients has had a ransom or breach using Untangle."
 

Cons

"Its pricing can be better."
"There is room for improvement related to the logging and reporting aspect."
"Some of the software stability could improve."
"Some features in Fortinet FortiGate need improvement as we discover when calling support that certain actions must be done from the command line."
"I would like to see improvements in the IPS/IDS feature to enhance protection against attacks from attackers, including ransomware protection."
"The software is a bit expensive to renew."
"In our case, the deployment options of FortiGate Next Generation Firewall (NGFW) are not scalable, but in terms of connectivity to other companies, that's exactly what we needed, and that's exactly what it does perfectly, what is needed."
"The solution could be more secure and stable."
"I would like to see the threat intelligence capability integrated with other vendors such as Cisco and Forcepoint."
"The scalability of Palo Alto Networks K2-Series is good. It is good for larger environments over smaller ones."
"It would be really helpful to have dashboards that provide information on IOC blockings such as where and how many. It will also be good to know how many hashing files have been reported. It would also be nice to have easy access to this information. Otherwise, it's a painful, manual task."
"They should implement the features that the other firewalls have."
"The graphical user interface is a little complex and difficult to manage. L1 engineers cannot work on the Palo Alto Networks K2-Series because it's too complex, which requires L2 and above level of engineers."
"I cannot think of anything specific to improve at the moment."
"The scalability for on-premises version is limited as it depends on the model."
"We had some issues with upgrading in the past. They could make the process easier."
"We seek the availability of the hardware in our region. The hardware-based firewall from Untangle is currently not available in our region. It should have threat protection on a real-time basis. This feature, available in Check Point and Sandstorm kind of scenario, is currently missing in Untangle NG Firewall."
"The pricing is not as good as it was some time ago. They've since skipped offering a lot of individual features."
"It would be much easier if there was a mobile app."
"The user interface, training, and general product innovation need improvement."
"It does have multi-factor authentication in some areas, but I would love to see a more widely implemented version of that on the devices themselves."
"The management console for partners is a bit tricky (buggy)."
"The storage is minimal, so we have to set the system to delete data after seven days."
"On their low-end appliance, they could have more memory and the largest storage space. The low-end appliance comes with a too-small hard drive, and it could use a little extra room. It only comes with about 4 gigs or 8 gigs of memory, and the hardware space is only 40 gigs, which is really small."
 

Pricing and Cost Advice

"I would say that all things considered, the pricing is pretty good."
"Its pricing is competitive with other solutions."
"There is no challenge in Fortinet FortiGate pricing."
"The pricing for this solution is reasonable."
"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."
"You need to pay a license for this solution. Our licensing is now done in our subsidiary."
"Fortinet FortiGate's price can be reduced."
"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."
"Palo Alto Networks K2-Series is an expensive solution, the price could be reduced. They are more expensive than some of their competitors."
"This product is designed for large companies. The price would not be suitable for a small or medium size company."
"The overall price of Palo Alto Networks K2-Series could be reduced."
"We are on an annual license to use Palo Alto Networks K2-Series."
"The price of this solution is too high."
"The pricing is expensive."
"This is an expensive solution, although you will get value for the price."
"Products by the leader in the field are justifiably a bit more expensive compared to other vendors."
"Untangle is open-source software. So, you can get it for free. That has been a benefit, especially for the residential users because it is free. The license costs start at $25 a month for some additional features, including higher tiers of security intrusion prevention. The free version comes with intrusion detection, and then the license version has intrusion prevention. It also has some additional things for active directory connectors, etc. It starts at $25 a month to cover 12 devices. Then it goes up from $25 to $50 a month for 12 to 25 devices. That's where it really doesn't scale out per site. If you have a site that has more than 50 devices on it, then Untangle quickly becomes cost prohibitive in comparison to several other competitors."
"It is the most cost-effective to use."
"It is not expensive. It is cheaper than Fortinet."
"This is not an expensive product. It is affordable and there are different packages available depending on the features that you need, or the sector that you are in."
"The solution is fairly priced."
"It is not expensive. The best part is that it is based on the pay-per-use kind of scenario. An increase or decrease in the number of people doesn't make any difference. We are really happy about using this particular scenario."
"The pricing model is better than with SonicWall."
"We pay $350 USD per year for the solution. There are no additional costs. As long as you're not using a physical appliance, that's all you need."
