Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The ASDM (Adaptive Security Device Manager) which is the graphical user interface, works out, and Cisco keeps it current.""It is a very stable product. I've not had any issues with it. It is a super product, and I won't need to change it anytime soon.""The CLI is the most valuable feature. This solution is very flexible and offers different functionality including firewalls and VPN connectivity.""They are easy to maintain.""The management aspect of the product is very straightforward.""Cisco ASA Firewall is a well known product. They're always updating it, and you know what they're doing and that it works.""I like that Cisco Firepower NGFW Firewall is reliable. Support is also good.""If you compare the ASA and the FirePOWER, the best feature with FirePOWER is easy to use GUI. It has most of the same functionality in the Next-Generation FirePOWER, such as IPS, IPS policies, security intelligence, and integration and identification of all the devices or hardware you have in your network. Additionally, this solution is user-friendly."

"The system in general is quite flexible.""OPNsense is highly stable.""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.""It's more secure and more reliable.""The initial implementation process is simple.""OPNsense could improve by making the configuration more web-based rather than shell or command-line-based.""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.""We have found pretty much all the features of the solution to be valuable."

Cons
"Some individuals find the setup and configuration challenging.""It would be nice if you didn't have to configure using a command-line interface. It's a bit technical that way.""Cisco ASA Firewall could improve by adding more advanced features such as web filtering, which is available in the next-generation firewalls. However, the Cisco ASA Firewall I am using could be old and these features have been updated.""A major area of improvement would be to have more functionality in public clouds, especially in terms of simplifying it. The high availability doesn't work right now because of the limitations in the cloud.""My team tells me that other solutions such as Fortinet and Palo Alto are easier to implement.""Cisco Firepower NGFW Firewall can be more secure.""Cisco Firepower is not completely integrated with Active Directory. We are trying to use Active Directory to restrict users by using some security groups that are not integrated within the Cisco Firepower module. This is the main issue that we are facing.""I'm not a big fan of the FDM (Firepower Device Manager) that comes with Firepower. I found out that you need to use the Firepower Management Center, the FMC, to manage the firewalls a lot better. You can get a lot more granular with the configuration in the FMC, versus the FDM that comes out-of-the-box with it. FDM is like Firepower for dummies."

More Cisco Secure Firewall Cons →

"The support for OPNsense is good because we have documents available on the internet. The support could improve a little.""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 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.""Its interface should be a little bit better.""I would like to see better SD-WAN performance.""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.""The solution could be more secure."

Pricing and Cost Advice
  • "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."
  • "The product is very expensive."
  • "This is an expensive product, although when you buy this solution, you can do many things so it provides good value for the investment."
  • 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."
