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.

Application control excels and integration with monitoring system boosts efficiency
I am an integrator working with Palo Alto Networks CN-Series and Panorama. I have been involved with the implementation of Palo Alto Networks CN-Series The stability of Palo Alto Networks CN-Series is excellent. Application control is one of the most valuable features. Its monitoring capability…

A robust appliance that is reasonably priced and straightforward to set up
Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

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

Pros

"The dynamic segmentation feature in Fortinet FortiGate is pretty good."
"It's quite comfortable to handle the FortiGate firewall."
"The initial setup is straightforward."
"The solution is scalable."
"We use a lot of function on the IPS and it works well for us."
"Security solution with a straightforward and quick setup. It's a stable and scalable product."
"The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with."
"Fortinet FortiGate is used to prevent security failures. Since implementing the solution, we have seen improvements in security and in the distribution of our network."
"The app inspection is very helpful for network security."
"The stability of Palo Alto Networks CN-Series is excellent."
"The solution can scale well."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"This is a capable appliance and the standard features work well for us."
 

Cons

"There is a lot of improvement needed with SSL-VPN."
"There are some tiny bugs that sometimes affect the operations. In the past revision of it, there was a bug. Because of the bug, we had to downgrade the version. It happened only with the last revision."
"At this moment, we believe that Fortinet FortiGate should be improved by injecting more AI because the kind of threats we are seeing are more ransomware threats. Fortinet FortiGate is able to ensure these threats do not enter, but we would prefer to see more proactive alerting mechanisms come out."
"The UI could be improved."
"Sometimes you do need to know some CLI commands, so it's a bit harder for technicians or new people that don't know it."
"I wish that they could integrate zero-trust technology into Fortinet FortiGate. I am not sure whether it has been done already, but if they could implement that, it would help significantly."
"I would rate the technical support of Fortinet FortiGate as a five because it is not as strong as Cisco. Additionally, the turnaround time is very high compared to Cisco."
"WAN load-balancing could be a lot better at detecting when a link is poor or inconsistent, and not just flat out dead."
"I'd like to see more IOPs features."
"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
"The product has some scalability and data management issues where improvements are required."
"Sometimes it reboots when you least expect it, and that's the main issue."
"Although manageable, the user interface is a little bit slow and could be improved."
 

Pricing and Cost Advice

"The price of Fortinet FortiGate could improve, it is expensive."
"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."
"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."
"You need to pay a license for this solution. Our licensing is now done in our subsidiary."
"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."
"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."
"The pricing of Fortinet FortiGate is average, not cheap or overly expensive compared to other firewall solutions in the market. It's effective and affordable for customers."
"Compared to Palo Alto, which we have used in the past, pricing and licensing are okay."
