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.

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

"We are very happy with the general bandwidth agility we have seen from one website to another website."

"User-friendly and affordable security solution that's recommended for SMB customers. This solution has good technical support."

"Advanced routing (RIP, OSPF, BGP, PBR). It gives you a seamless and simple integration into a large network."

"The most valuable features are simplicity, management, and that it's constantly evolving."

"Security management tool that's easy to integrate and easy to work with. No issues found with its stability and scalability."

"It's great for capturing the traffic and troubleshooting it."

"The performance is good."

"I like how we can achieve total integration."

More Fortinet FortiGate pros

"It's open source."

"OPNsense is highly stable."

"The technical support is very good."

"OPNsense is easy to use and open source."

"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."

"The interface and the dashboard are the most valuable features of this solution."

"I feel that its valuable features are that it is simple and free."

"The IDS and IPS features are valuable. From the usability perspective, there is a lot of good documentation. As IT professionals, we found it very easy to configure the firewall. It was easy to configure and use."

More OPNsense pros

"Application Control and filtering features are valuable."

"The majority of our clients are very small businesses, and Untangle devices have been fantastic for these small clients. We've basically standardized our stack to just simply use Untangle. We include the hardware and the service option, which makes it very easy and affordable for us to just simply push that into the monthly per-user costing that we provide as a managed services provider. It's really a no-brainer. They're easy to use, and they're easy to set up and configure. Support is generally good about resolving any issues that we have. We haven't had any real complaints."

"The most valuable features are IPS, MAPI, NAT, and VPN."

"Easy to set up and easy to integrate."

"All features are useful. We are using premium features such as bandwidth sharing, failover, web filters, SSL controls, antivirus, and VPN. We use these features to the fullest. These features are available in the paid firewall license, not the free one."

"The product’s most valuable features are endpoint protection management, load balancing, and connectivity with Active Directory."

"It is very easy to deploy and monitor. "

"Web filtering is very reliable."

More Untangle NG Firewall pros

Cons

"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."

"Its reporting can be improved. Sometimes, I don't get proper reports."

"I feel that the reporting needs to be improved."

"With FortiGate, the main complaint that I have heard is about the technical support."

"WAN load-balancing could be a lot better at detecting when a link is poor or inconsistent, and not just flat out dead."

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

"At this moment, we believe that Fortinet FortiGate should be improved by injecting more AI because the kind of threats we are seeing are more ransomware threats."

"The sniffing packets or packet captures, can be simplified and improved because it's a little confusing."

More Fortinet FortiGate cons

"The ability to set the VPN IP address would be a welcome addition."

"In terms of improvement, the performance could be enhanced."

"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."

"We did not like the fact that you have to configure everything with the graphic user interface. We have used other firewalls, such as FortiGate, that you can configure via code. OPNsense is not easy to integrate. When you are deploying via GitHub or another source repository, this is not possible. That's one thing we didn't like much."

"pfSense has better performance and quicker updates."

"They should improve IPEs for security in the future."

"I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly."

"The scalability needs improvement."

More OPNsense cons

"On their low-end appliance, they could have more memory and the largest storage space. The low-end appliance comes with a too-small hard drive, and it could use a little extra room. It only comes with about 4 gigs or 8 gigs of memory, and the hardware space is only 40 gigs, which is really small."

"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 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."

"The management console for partners is a bit tricky (buggy)."

"We seek the availability of the hardware in our region. The hardware-based firewall from Untangle is currently not available in our region. It should have threat protection on a real-time basis. This feature, available in Check Point and Sandstorm kind of scenario, is currently missing in Untangle NG Firewall."

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

"The user interface, training, and general product innovation need improvement."

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

Pricing and Cost Advice

"It is not a very costly product if you compare it with other products. The return on investment is also good. If you compare the return of investment and money that you are spending on this product with Palo Alto, Cisco, Check Point, and other solutions, the investment is very less. We are happy with this solution. The optional licenses are there, and you can choose which one you want and which one to avoid."

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

"The price is fine."

"The value is the capability of having multiple services with one unique license, not having the limitation per user licensing schema, like other vendors."

"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."

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

"The price for the device and software is high. However, the solution is of good quality and has a lot of features."

"For medium and enterprise organizations, FortiGate is more affordable."

More Fortinet FortiGate pricing and cost advice

"The solution is not expensive."

"It is free."

"We are not paying any licensing fees. OPNsense is completely free for us."

"I would rate the pricing three out of ten."

"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."

"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."

"It's not expensive."

"There are no licensing costs for OPNsence."

More OPNsense pricing and cost advice

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

"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."

"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."

"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 pricing model is better than with SonicWall."

"This is not an expensive product. It is affordable and there are different packages available depending on the features that you need, or the sector that you are in."

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