Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable feature is that it's secure.""The configuration capabilities and the integration with other tools are the most valuable features. I really like this product. Cisco is one of my favorite brands, and I always think Cisco solutions are very reliable, easy to configure, and very secure.""The IP filter configuration for specific political and Static NAT has been most valuable.""I have access to the web version of Cisco Talos to see the reputation of IP addresses. I find this very helpful. It provides important information for my company to obtain the reputation of IP addresses. The information in Talos is quite complete.""The most valuable feature is the Intrusion Prevention System.""The features that are most valuable within the firewall are the IPS as well as the Unified Communications. We also really like the dynamic grouping.""The remote access, VPN, and ACL features are valuable. We are using role-based access for individuals.""ASA integrates with FirePOWER, IPS functionality, malware filtering, etc. This functionality wasn't there in the past. With its cloud architecture, Cisco can filter traffic at the engine layer. Evasive encryptions can be entered into the application, like BitTorrent or Skype. This wasn't possible to control through a traditional firewall."

More Cisco Secure Firewall Pros →

"OPNsense is easy to scale when running on the hardware.""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 most valuable features are reporting, the Sensei plugin, and firewall capabilities.""It has an open license. It works very well, and there is an update every month.""OPNsense could improve by making the configuration more web-based rather than shell or command-line-based.""We have found pretty much all the features of the solution to be valuable.""The system in general is quite flexible.""The initial implementation process is simple."

More OPNsense Pros →

"Its detection, antivirus, and filtering features are the most valuable. The facility to connect by using the VPN connection is also a very valuable feature. It is very strong, secure, and reliable. We have implemented the Untangle solution in all hardware. It is also a user-friendly solution. It is easy to learn and easy to configure.""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.""The web blocking for my clients and the application control are valuable.""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 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.""They have a command center that makes it easy to log into and see all of your appliances nationwide."

Cons
"The configuration is an area that needs improvement.""Most of the features don't work well, and some features are missing as well.""There is huge scope for improvement in URL filtering. The database that they have is not accurate. Their content awareness and categorization for URL filtering are not that great. We faced many challenges with their categorization and content awareness. They should improve these categorization issues.""There are some limitations with SSL. Regarding the security assessment for the ISO 27000 standard, there are certain features that Cisco needs to scale up. Not all products support it, so you need to be slightly careful, especially on the site track.""Setting firewall network rules should be more straightforward with a clearer graphical representation. The rule-setting method seems old-fashioned. The firewall and network rules are separate from the Firepower and web access rules.""The maturity needs to be better.""An area for improvement is the graphical user interface. That is something that is coming up now. They could make the product more user-friendly. A better GUI is something that would make life much easier.""One of the few things that are brought up is that for the overall management, it would be great to have a cloud instance of that. And not only just a cloud instance, but one of the areas that we've looked at is using an HA type of cloud. To have the ability to have a device file within a cloud. If we had an issue with one, the other one would pick up automatically."

More Cisco Secure Firewall Cons →

"I would like to see better SD-WAN performance.""The solution could be more secure.""They should improve IPEs for security in the future.""The support for OPNsense is good because we have documents available on the internet. The support could improve a little.""OPNsense could improve by making the configuration more web-based rather than shell or command-line-based.""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.""The IPS solution could be more reliable.""The logging could improve in OPNsense."

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.""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 biggest challenge that we have with this solution is local support. The local support is a problem in our area.""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.""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.""They don't have any feature that allows you to drop the session."

Pricing and Cost Advice
  • "This product is expensive."
  • "If we compare it with FortiGate and the co-existing ASA, FortiGate is better in price."
  • "They seem to be at the top end in terms of pricing, but they are worth the price. They are probably a little bit lower than Palo Alto. If the customers are relying on Cisco products and they are thinking more in terms of scaling to another layer in a year, it is pretty much in a good price range."
  • "We're using the smart license for this firewall. The models that we have require licensing for remote access."
  • "There are licensing costs."
  • "I just bought it off the shelf, and I'm using it with my previous one, so I have not spent that much."
  • "The price is fair. It's not the cheapest, but it's not bad."
  • "For me, personally, as an individual, Cisco Firepower NGFW Firewall is expensive."
  • More Cisco Secure Firewall Pricing and Cost Advice →

  • "OPNsense is an open-source solution and it is free to use."
  • "The solution is not expensive."
  • "As an appliance, it's in the medium price range."
  • "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 open source and free."
  • "The price of OPNsense is good."
  • More OPNsense Pricing and Cost Advice →

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