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.

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 next-gen features, the unified threat management capabilities are something that just about everybody is interested in at this point."

"The solution is stable."

"The threat prevention is the solution's most valuable aspect."

"It performs very well."

"The most important features of Fortinet FortiGate are the Intrusion Prevention System (IPS) and firewall control applications."

"From the firewall perspective, the rules and policies are very sufficient and easy to use."

"It is easy to manage, and it doesn't need much knowledge from the team. It is a stable device, and there are many features that are included out of the box."

"We are a visual effects company, and there have been a number of high profile security issues in our industry. This has brought us to a higher standard of security, which our clients are very keen on these days."

More Fortinet FortiGate pros

"The tool's integration is more like a button press."

"OPNsense is easy to use and open source."

"The DNS-level filtering is impressive for thwarting time scanners."

"The solution is good for a basic firewall for a small business or for home use."

"The most valuable features are reporting, the Sensei plugin, and firewall capabilities."

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

"I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed."

"The technical support is very good."

More OPNsense pros

"I like the filtering feature, which provides easy access. The SSL certification feature is also nice. The solution enhanced our security posture."

"The product's most valuable features are simplicity and comprehensive protection capabilities, including load balancing, IPS, antivirus, and web filtering."

"SonicWall has helped us deliver security solutions effectively, particularly in threat prevention and content filtering."

"It has been delivering results efficiently. Its configurations and updates have been easy. It is also user-friendly."

"The solution's pricing is good."

"SonicWall NSSP is stable and scalable too."

"The VPN functionality is really good. Overall, the whole device is very easy to manage. The software that comes with it is also good."

Cons

"It would be nice if FortiGate incorporated some built-in endpoint protection features. I would also like a built-in SOC dashboard for managing multiple Fortinet firewalls."

"I would like to see improvements in the product's application rules."

"The only issue that I have is with FortiNAC. The firewall is fine, but the FortiNAC interface is a little bit too jumbled or too complicated, not as straightforward as it is on the Fortinet FortiGate firewall and FortiAnalyzer."

"The logging details need to be improved."

"A couple of things I've seen that need improvement, especially in terms of a hard coding. The driver-level active moment really is out-of-the-box and we have to have contact the customer support and sometimes it is difficult to resolve."

"Stability and technical support are the two major issues I have found with Fortinet."

"If they had better integration with security products, such as Cisco ISE or Rapid Threat Containment, then it would be an improvement."

"Fortinet FortiGate needs to improve the protection, it did not prevent us from being attacked. Additionally, Fortinet FortiGate could provide more features for WAF devices. I should not have to purchase two solutions, it would be a benefit to combine these features into one solution."

More Fortinet FortiGate cons

"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."

"The IPS solution could be more reliable."

"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."

"I would like to see better SD-WAN performance."

"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."

"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."

"The user interface could be improved, and the DNS section should be more intuitive."

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

More OPNsense cons

"No security product is foolproof against hackers, intruders, and other such things. As a security product, they have to keep pace in terms of protection from new hackers and intruders."

"The platform could benefit from an improved marketing strategy."

"The product needs improvement for phishing emails."

"The EDR and XDR capabilities of SonicWall need to be improved."

"The solution's stability and scalability also need improvement."

"The user interface, the GUI, could be improved."

"Its reporting functions can be improved. It has decent reporting, but you got to pay a lot more money for it. That's where it begins to fall apart. It comes with minimal zero reporting unless you buy some extra modules. With those extra modules, you can get all the data, but it takes a while to put together what you need for your customer. It is for technical people, but there is no executive summary of the reporting."

Pricing and Cost Advice

"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."

"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."

"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."

"I think that the pricing is fair."

"When I look around at other products, such as Sophos, Fortinet FortiGate is 20% to 30% more expensive with our current cost."

"By default, they give SD-WAN along with the firewall. They don't have separate licensing for the SD-WAN functionality. However, they have security licenses that are sold separately on a subscription basis. Customers can consume these security features to protect their users from internet traffic."

"They need to be competitive with other solutions."

"We have the full version of Fortinet FortiGate and we are on a three-year contract with a commitment of five years."

More Fortinet FortiGate pricing and cost advice

"It's not expensive."

"It is free."

"Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."

"The solution is not expensive."

"The price of OPNsense is good."

"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 three out of ten."

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

More OPNsense pricing and cost advice

"The setup costs and licensing are reasonable, and the solution provides good value for its features."

"For SonicWall NSSP high availability, active/passive, you need to buy one license, and so you get much more value for money."

"I rate the solution's pricing a six out of ten."

"You got to buy some VPN licenses, and there might be a $40 to $50 one-time license fee per current user. There are different layers. They have several different levels of event security software and depending on the model, it seems to come out to be $1 to $2 a day. So, if you bought a three-year license, it is going to be anywhere from $900 to $1800 depending on the bundle and model that you buy."

"The pricing is cheap, and that's where, you know, the some of the organization goes for the SonicWall."
