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.

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.

Thorough with all-in-one security functions and good affordability

The all-in-one gateway security functions and the ability to install it on generic equipment stand out. The centralized management console is great. I can template my installations and configurations. My ability to monetize it as a gateway security appliance to offer enhanced service offerings allows me to increase our price point. I provide it as a managed device to many of our clients. I take on the initial costs and charge them a monthly fee. They have threat detection.

Quotes from Members

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

Pros

"This is an easy solution to deploy."

"The most valuable features of Fortinet FortiGate are it is one of the most mature firewalls in the UTM bundle."

"We are using the FortiGate 100D series. VPN, firewall, anti-malware, OTM, and intrusion prevention are useful features."

"A strong point of FortiGate is that the graphical interface is complete and easy to use, especially if we think there is a list of operations that we are able to perform inside."

"The security features that they have are quite good. On top of that, their licensing model is quite nice where they don't charge you anything for the SD-WAN functionality for the firewall."

"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 has a very good solution for Secure SD-WAN. One very good feature is that they have robust and simple FortiOS through which they provide all solutions. That's their strength. There's not much complexity involved with the Secure SD-WAN solution of Fortinet as compared to Cisco's solution, which has a lot of flexibility but complexity also comes with that flexibility."

"Customers are more inclined towards FortiGate because of application control, web filtering, and anti-spam features. The support from the FortiGate team is good, and price-wise, it is affordable."

More Fortinet FortiGate pros

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

"Palo Alto's App-ID is what differentiates it from other competitors."

"The most valuable feature is availability."

"The most valuable feature of Palo Alto Networks K2-Series is the configuration, it is very clear."

Cons

"The support team for Fortinet FortiGate needs to be more customer friendly."

"Fortinet FortiGate could improve by having better visibility. Palo Alto has better visibility."

"One area for improvement is the performance on bandwidth demands for smaller devices, as well as better web filtering."

"There are some complex administration tasks in their administration portal. That needs to be improved."

"The price of FortiGate should be reduced because there are some other leading products that are cheaper."

"Fortinet FortiGate could improve if it had a cloud-managed solution."

"They need faster serviceability and more security features."

"I have to say that the initial setup was complex. The deployment took a few days to get set up. Initially, we were using an IPVanish. We switched to this tool since we thought it would be easier. But it turns out it wasn't easier to set up and run."

More Fortinet FortiGate cons

"Sometimes there are interactions with support or the provider that are not ideal."

"The ease of management and configuration should be improved."

"Its networking features could be better."

"In the past, we've had trouble with Palo Alto's application filtering not getting it right. I would not be recommending layer 7 application filtering yet."

"It is recommended that the Palo Alto Networks K2-Series be implemented step by step for the Panorama. Sometimes we can't overwrite the configurations because it fails."

"There are a lot of bugs in this solution."

"They could improve by providing more features in the solution."

"They should implement the features that the other firewalls have."

More Palo Alto Networks K2-Series cons

"The product needs to improve its mobile application."

"The solution's licensing count could be improved."

"They don't have any feature that allows you to drop the session."

"The common center facility that Untangle provides should be available on-premises. There are great corporations here in Mexico that like the Untangle solution, but they don't like the fact that the monitoring and access to the appliance are in the cloud. They request for the common center facility to be available and installed on-premises."

"It does have multi-factor authentication in some areas, but I would love to see a more widely implemented version of that on the devices themselves."

"The hardware can be improved."

"The product needs to have a better support group for its online support, specifically for its help desk."

"The web content filtering needs improvement."

Pricing and Cost Advice

"I had to pay for the license for the firewall, but it is guaranteed to have updates. I expect a good service for it. It was about €1000 for a year, and there was no additional cost."

"It is cost-effective, and provides a good value for your money. The pricing, and license renewal, is very reasonable for us."

"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."

"The licensing scheme of Fortinet is better than Cisco. It is more logical."

"If the price of the license in Fortinet FortiGate was less expensive it would be better."

"The pricing is fair."

"Fortinet FortiGate has different licensing models, depending on what you're going to do. Services included would depend on the license model. Licenses can be renewed annually."

"The price of Fortinet FortiGate is reasonable."

More Fortinet FortiGate pricing and cost advice

"It would be nice if they lowered their prices for small businesses."

"It is an expensive solution."

"Palo Alto firewalls are very expensive."

"If you compare K2-Series' quality with its price, I think it is reasonable."

"We are on an annual license to use Palo Alto Networks K2-Series."

"The price of this solution is too high."

"Pricing is a sensitive issue because the cost is high in this market."

"When comparing Palo Alto Networks K2-Series with other solutions it is on the higher end of the price scale."

More Palo Alto Networks K2-Series pricing and cost advice

"It is not expensive. It is cheaper than Fortinet."

"Untangle is open-source software. So, you can get it for free. That has been a benefit, especially for the residential users because it is free. The license costs start at $25 a month for some additional features, including higher tiers of security intrusion prevention. The free version comes with intrusion detection, and then the license version has intrusion prevention. It also has some additional things for active directory connectors, etc. It starts at $25 a month to cover 12 devices. Then it goes up from $25 to $50 a month for 12 to 25 devices. That's where it really doesn't scale out per site. If you have a site that has more than 50 devices on it, then Untangle quickly becomes cost prohibitive in comparison to several other competitors."

"It is not expensive. The best part is that it is based on the pay-per-use kind of scenario. An increase or decrease in the number of people doesn't make any difference. We are really happy about using this particular scenario."

"The solution is fairly priced."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing an eight out of ten."

"The tool's pricing is moderate, and licensing costs are yearly."

"We pay $350 USD per year for the solution. There are no additional costs. As long as you're not using a physical appliance, that's all you need."

"Usually, it's about $350 a year for 12 users, and it's about $600 for 50 users. It's very reasonable as compared to the others. One of the reasons is that they're all open-source. You just buy their appliance and put it in until it dies. Because it's run under open platforms, mine seems to always work on older equipment. I've taken old equipment and put a new hard disk in it. I have taken about nine-year-old computers and put their operating system on them, and ran them like a champ. The only thing that changed was the hard drive because I don't trust a hard drive that's more than three to four years old."

Reviews from Real Users

Untangle NG Firewall is a solution that stands out when compared to many of its competitors. Some of its major advantages are that it is easy to use, has good features, including VPN, reporting, alerting, and filtering, and can be installed on existing hardware.

“It is very easy to use. The user interface is very straightforward. It may not be as fancy as some of the ones I've seen, but it's very straightforward. It's very easy to find what you need, and it's very easy to get things done,” says Josh E., CEO at DragonTech IT Services, Inc.

Barry A., Owner at ThinkEzIT, says, “It has good VPN features, helpful reporting and alerting, built-in content filtering, and excellent support.”

PeerSpot user Victor O., Director at Kisii County Government, explains, “What I like about this product, which is the reason that we continue to use it, is that you can install the software version on your own hardware. In case there is a problem with the hardware, we can just install the firewall in another machine and restore the configuration.”
