Efficient, user-friendly, and affordable

In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

IT Security Director at a financial services firm with 1,001-5,000 employees

Good interface and firewall capabilities and overall easy to use

The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.

Quotes from Members

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

Pros

"The solution is very user-friendly."

"This solution has helped our organization by having strong functions and a reliable firewall."

"Some of the valuable features are the firewall, IPS, web filter, and gateway capabilities. Additionally, it is easy to use and flexible."

"The notable features that I have found most valuable are that it includes the antivirus, and also IPS, and even SD-WAN."

"Security solution with a straightforward and quick setup. It's a stable and scalable product."

"The user interface (UI) is very, very good."

"It works very well. It has a lot of different functionalities. Its cost is also fine for our customers."

"It is easy to use. We chose this product for the possibility to have virtual domains (VDOMs). We are building another company in the group, and we would like to split the firewalling rules and policies between these two companies. Each company would be able to manage its own policies and security rules, which is an advantage of Fortinet FortiGate. We can define VDOMs, and every company can manage its own VDOM as if it has its own physical firewall, but in fact, we would be using the same physical appliance because we are also using the same internet lines. So, it allows us to reuse the existing resources without the disadvantage of having to compromise on policies and security. Each company can choose its own way of working."

More Fortinet FortiGate pros

"Five out of five ROI."

"The installation is easy, we have not had any complaints from our customers."

"Very reliable solution with good scalability and straightforward implementation."

"Stability-wise, I rate the solution a ten out of ten."

"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."

"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients a secure connectivity."

"The most valuable feature of the Hillstone E-Series is its user-friendliness."

"I am impressed with the application filtering feature."

More Hillstone E-Series pros

"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."

"The solution is user-friendly and easy to configure."

"The technical support is very good."

"It's more secure and more reliable."

"The system in general is quite flexible."

"It's open source."

"We have found pretty much all the features of the solution to be valuable."

More OPNsense pros

Cons

"Its pricing can be better."

"Fortinet technical support is lacking, as OEM support is slightly better."

"Fortinet FortiGate could improve by adding enhancements to FortiMail, FortiSOAR, and FortiDeceptor."

"I would like reporting to be improved and should offer a lot more tools to monitor the products."

"There's always something new that can be added or fixed."

"FortiLink is the interface on the firewall that allows you to extend switch management across all of your switches in the network. The problem with it is that you can't use multiple interfaces unless you set them up in a lag. Only then you can run them. So, it forces you to use a core type of switch to propagate that management out to the rest of the switches, and then it is running the case at 200. It leaves you with 18 ports on the firewall because it is also a layer-three router that could also be used as a switch, but as soon as you do that, you can't really use them. They could do a little bit more clean up in the way the stacking interface works. Some use cases and the documentation on the FortiLink checking interface are a little outdated. I can find stuff on version 5 or more, but it is hard to find information on some of the newer firmware. The biggest thing I would like to see is some improvement in the switch management feature. I would like to be able to relegate some of the ports, which are on the firewall itself, to act as a switch to take advantage of those ports. Some of these firewalls have clarity ports on them. If I can use those, it would mean that I need to buy two less switches, which saves time. I get why they don't, but I would still like to see it because it would save a little bit of space in the server rack."

"Improvement is needed in the Web Filter quotas to restrict users with allocated quotas."

"It could use more templates for third-party site-to-site VPN setups other than FortiGate and Cisco."

More Fortinet FortiGate cons

"The current usage reporting is very basic."

"SSL VPN license cost is not cheap."

"Support from Hillstone E-Series has a shortcoming that needs improvement."

"Having frequent live webinars on a monthly basis would really help."

"The tool only had some memory-related problems."

"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

More Hillstone E-Series cons

"There are issues with stability and reliability."

"There are some add-ons that need enhancements to make management easier for users, especially the reporting features. Some reports don't show the level of detail I'm looking for, and I've had trouble installing certain add-ons, especially for Internet bandwidth shaping within my company."

"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."

"The solution would not be suitable for anything large-scale."

"The logging could improve in OPNsense."

"The scalability needs improvement."

"While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet."

"pfSense has better performance and quicker updates."

More OPNsense cons

Pricing and Cost Advice

"The cost of Fortinet FortiGate is competitive and not expensive compared to other enterprise- grade solutions. On average, the license cost per year is around seventy percent of the firewall's purchase price."

"In the Asian economy in which we operate, FortiGate is expensive."

"Fortinet FortiGate's price can be reduced."

"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."

"The price is really low. It's cheap in comparison to the cost of Cisco or CheckPoint, for example."

"Pricing is lower than Cisco."

"The pricing of the solution is very competitive."

"It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."

More Fortinet FortiGate pricing and cost advice

"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."

"Hillstone's pricing is economical and neither very high nor very low."

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."

"We are using the paid version."

"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."

"It is free."

"I've used the free version. My computer with two network cards at home allows me to try as many different software options as I want. I did pay for the license, but it was for the Zenarmor license, which is the packet inspection tool. They use AI for packet inspection, which integrates with OPNsense and pfSense."

"It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."

"There are no licensing costs for OPNsence."

"It's not expensive."
