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.

Highly scalable, user-friendly UI, and easy to maintain
We have used Juniper SRX Series Firewall in airports and multiple other industries The most valuable features of the Juniper SRX Series Firewall are the user-friendly UI, and accessing the solution is simple. The pricing strategy of the vendor could improve. I have been using Juniper SRX Series…

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

"I like that they have given me a solution at a fair price."
"The product is easy to use and is stable. The SV1 functionality is a benefit."
"Some of the valuable features are the firewall, IPS, web filter, and gateway capabilities. Additionally, it is easy to use and flexible."
"The most valuable features of Fortinet FortiGate are the different types of profiling. It has been the most effective for me. The WAF and the antivirus profile are the most effective in network protection."
"A strong point of FortiGate is the graphical interface is complete and easy to use."
"The most valuable features of Fortinet FortiGate are the APIs. They are the most widely known."
"It is user friendly, and has all the features you need."
"Allows for firewall rules to be programmed and named in a way that makes it “readable”"
"It is a part of the infrastructure when we're selling Juniper. That's what clients are familiar with and that's what they rely on."
"The rollback option and Commit Confirmed are great features. They give us the security to change configurations without downtime."
"I like the routing and firewall features."
"The most valuable features of the Juniper SRX Series Firewall are the user-friendly UI, and accessing the solution is simple."
"Once a customer starts to use Juniper products, they never switch to another brand."
"The solution is stable, inexpensive, and works well for medium size companies."
"I like that Juniper SRX is easy to use, scalable, and stable with good performance."
"When compared to Palo Alto, Juniper is a better choice when it comes to the enterprise network and connectivity."
"I feel that its valuable features are that it is simple and free."
"OPNsense is easy to use and open source."
"The interface and the dashboard are the most valuable features of this solution."
"It's more secure and more reliable."
"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed."
"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."
"OPNsense is very stable, easy to upgrade, and maintain."
"What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
 

Cons

"The feature which gives us a lot of pain is ASIC architecture."
"We would like to see better pricing."
"The anti-malware engine could use an upgrade."
"I would like to see more advanced developments of a wireless controller in the future."
"Its filtering is sometimes too precise or strict. We sometimes have to bypass and authorize some of the sites, but they get blocked. We know that they are trusted sites, but they are blocked, and we don't know why."
"The user interface could be improved to make it less confusing and easier to set up."
"We sometimes have issues with FortiGate's routing table in the latest firmware update. We had to downgrade the device because our customers complained about bugs."
"There is room for improvement related to the logging and reporting aspect."
"I would like to see endpoint control and endpoint testing security."
"The CPU switch could be improved for a better overall performance of traffic flow."
"The solution could cost less. It's a bit expensive right now."
"It would be good if Junos had "unique commands" between all hierarchical levels, discarding the use of the "Run" command."
"Juniper SRX is stable, but it could improve. FortiGate has better stability than Juniper SRX."
"The CLI is verbose. You have to say a lot to do a little. I don't like that part of it. Cisco's command syntax seems to be a good bit more concise. When you're trying to get something done, you don't want to have to type a bunch."
"In the future, I would like to see the UI more responsive"
"The web interface on Juniper SRX is just a short conversion from Junos OS CLI; this is not very suitable for users with little expertise/"
"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"In terms of improvement, the performance could be enhanced."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"The interface needs to be simplified. It is not user-friendly."
"The logging could improve in OPNsense."
 

Pricing and Cost Advice

"The price of FortiGate support is too expensive."
"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."
"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."
"The license of Fortinet FortiGate should be reduced."
"The price of FortiGate is good."
"We purchased a five-year bundle package, which worked out cheaper than competing solutions."
"The license is yearly. We pay for the top end. It's called 360."
"Fortinet FortiGate as a less expensive solution than Palo Alto."
"Pricing is good. Most of the costs are in the UTM (IDS/IPS, virus scanning, etc) subscription."
"I rate the solution's pricing as a four."
"There is value for money. It offers a good solution at a good price. The price is normal for such a product."
"This is a cost-effective solution because the price is very reasonable, and some of the features are available at no extra cost."
"The prices are very good as compared to other vendors."
"It is best suited to an enterprise-level, as the mid-range companies may find that the cost is not affordable."
"The pricing is perhaps half, probably forty percent, of Cisco."
"Its price is reasonable. In India, most of the products have a similar price. There is only a 5% to 10% variation in the price of different brands."
"It costs about $1000."
"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."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"There are no licensing costs for OPNsence."
"It's not expensive."
"OPNsense is open source software so at this time it is free for us to use."
"OPNsense is a well known open-source tool."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
