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.

Quotes from Members

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

Pros

"Web filtering is the most useful feature."

"The interface is very user-friendly and I like it very much."

"Fortinet FortiGate positively provides my clients' organizations with a high return on investment."

"This product is definitely scalable."

"FortiGate is easy to configure. We configured one of the units and sent it to Indiana to be installed. We asked them to give us a call when they got it, so we could help them through the process, but they called us back to tell us it works great."

"The security on offer is very good."

"There is a tool called FSSO, which is a single sign-on user ID agent that works perfectly."

"The usability of the solution is its best feature."

More Fortinet FortiGate pros

"I would rate the stability as ten out of ten for IPFire."

"IPFire has prevented any kind of hacking and enables us to comply with customer requirements."

"The most valuable feature of Palo Alto Networks K2-Series is the performance which is above their competitors. The throughput they have delivered is good. When we used other solutions they failed the deployment when we were using different rules. They have a theory perform performance light and performance degradation. However, Palo Alto Networks K2-Series never fails in that scenario."

"I have found the threat profile feature valuable."

"Overall, this is a very simple and very effective firewall, and I am satisfied with it."

"We've found the solution offers us good stability."

"As long as the solution is kept updated, it's pretty stable."

"It is a stable solution."

"Overall product rating: Nine out of ten."

"The most valuable feature is availability."

More Palo Alto Networks K2-Series pros

Cons

"The web-cache feature which was previously on the FortiGate device, but was deleted with the recent upgrade should be returned. It was a very valuable feature for us."

"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."

"The prevention mechanisms and implementation are not easy."

"I would like to see improvements made to the dashboard and UI, as well as to the reporting."

"There are a lot of bugs I have found in the solution and it is difficult to upgrade. These areas need improvement."

"Fortinet FortiGate SWG can be expensive for some customers."

"They should consider making some improvements regarding the pricing."

"I need user-behavior analytics, to find threat scenarios from inside the organization, insider attacks. That would be very helpful for us. In addition, I would like next-generation features for small and medium businesses. These businesses require UTM, all in one product. Fortinet must include it."

More Fortinet FortiGate cons

"Accessing the internet was a bit complicated."

"The graphical interface could be much better."

"The tool needs to improve integration with more products from other vendors. I would like the product to add threat intelligence features as well."

"The solution's commitment time could be reduced as it often takes a lot of time to execute."

"Palo Alto releases a lot of bug fixes for their firewalls, which means it's necessary to do frequent upgrades. They should work on decreasing their bugs so that upgrades aren't needed so often."

"The technical support, and how they provide it to the client, needs to be improved."

"The URL Filtering module needs to have more categories added to it."

"The product should get frequent updates allowing us to add new signatures."

"The password function of the solution could be improved. Additionally, some of the processes take too long to complete."

"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."

More Palo Alto Networks K2-Series cons

Pricing and Cost Advice

"Fortinet FortiGate is cheaper than Palo Alto. It is about 20% cheaper."

"It's expensive, but compared to the competition it's okay."

"The pricing is based on a licensing model for each IPS in your environment."

"Its pricing is good. The advantages of Fortinet FortiGate over its competitors include good pricing and meeting our requirements at a lower cost."

"I rate the product's pricing a seven out of ten. Its one-year license cost is competitive with three and five-year licenses offered by other products."

"The tool is a bit pricey for small businesses, but it is still bearable in terms of cost."

"Pricing and licensing is a little bit complicated in FortiGate. They are always on the higher side. This is one issue that we always raise with the company that they should reduce the price according to Indian market requirements. There are no costs in addition to the standard licensing fees."

"Compared to other firewall products, it's a little cheaper in terms of pricing."
