Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The TAC is always very helpful. We pay for Tier 1 support, so we get whatever we need from them. They always give us a solution. If they can't give us an answer that day, they get back to us within at least 24 hours with a solution or fix. I have never had a problem with the TAC. I would rate them as 10 out of 10.""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 important feature is the intensive way you can troubleshoot Cisco Firepower Firewalls. You can go to the bit level to see why traffic is not handled in the correct way, and the majority of the time it's a networking issue and not a firewall issue. You can solve any problem without Cisco TAC help, because you can go very deeply under the hood to find out how traffic is flowing and whether it is not flowing as expected. That is something I have never seen with other brands.""The most valuable feature would be ASDM. The ability to go in, visualize and see the world base in a clear and consistent manner is very powerful.""It has definitely improved our organization. It gives us remote connectivity, helps workers connect remotely, and also gives us good connectivity to our other branches.""The CLI is the most valuable feature. This solution is very flexible and offers different functionality including firewalls and VPN connectivity.""One of the most valuable features of Firepower 7.0 is the "live log" type feature called Unified Event Viewer. That view has been really good in helping me get to data faster, decreasing the amount of time it takes to find information, and allowing me to fix problems faster. I've found that to be incredibly valuable because it's a lot easier to get to some points of data now.""The fact that we can use Firepower Management Center gives us visibility. It allows us to see and manage the traffic that is going through the network."

"The initial implementation process is simple.""OPNsense is highly stable.""OPNsense is easy to scale when running on the hardware.""The technical support is very good.""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.""The system in general is quite flexible.""We have found pretty much all the features of the solution to be valuable."

More OPNsense Pros →

"We like their interface very much. It's pretty easy to use.""It does what it says it is going to do.""SonicWall TZ think it's a good, solid, and stable product.""We like the unified threat management for defense-in-depth. We can terminate our site-to-site and remote access VPNs with it.""The most valuable features are unified threat management which provides security intelligence and the VPN for both site-to-site and remote access.""With the main firewall routing there, we can do connectivity point-to-point. On the low bandwidth we can connect in all the branches with my corporate office.""It does exactly what it says on the tin. It is good for protecting the business from being compromised. Its port protection is very good.""The site-to-site VPN connections, content filtering, and in our current remote working situation, SSL VPN remote desktop connectivity are the most valuable features."

Cons
"I have used Fortinet, Palo Alto, and Check Point previously and I prefer the process of everything working together.""One thing that we really would have loved to have was policy-based routing. We had a lot of connections, and sometimes, we would have liked to change the routing depending on the policies, but it was lacking this capability. We also wanted application filtering and DNS filtering.""It needs to provide the next-generation firewall features that other vendors provide, like data analytics, telemetry, and deep packet inspection.""I think they need to review their whole UI because it feels like it was created by a whole bunch of different teams of developers who didn't fully talk to each other. The net policy screen is just a mess. It should look like the firewall policy screen, and they should both act the same, but they don't. I feel like it's two different buildings or programming, who don't talk to each other, and that really annoys me.""The ease of use needs improvement. It is complex to operate the solution. The user interface is not friendly.""Nowadays, nobody is in the office, so I need to figure out how to put the firewall outside. If I could have a centralized firewall that also receives information from external locations, like peoples' home offices, that would help us consolidate everything into one appliance.""The user interface is a little clunky and difficult to work with. Some things aren't as easy as they should be.""When we first got it, we were doing individual configuring. Now, there is a way to manage from one location."

"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 interface needs to be simplified. It is not user-friendly.""They should improve IPEs for security in the future.""The solution could be more secure.""An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense.""The support for OPNsense is good because we have documents available on the internet. The support could improve a little.""The logging could improve in OPNsense.""OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."

More OPNsense Cons →

"GUI interface could be improved.""Although the pricing is good, it could always be lower. If we get to pay less, we're happier.""Needs more robust self-help documentation along with examples and things to watch out for.""Sometimes there is a glitch between the network connection. Last time, something happened on our IP phone, the SonicWall team did some updates to fix the issue. However, glitches happen very rarely. I did not experience any other types of problems.""I think content filtering is the area this product should improve. It's a little tricky to get put in correctly.""The interface and technical support are probably the two most important things that I would like SonicWall to improve.""The log sections could be done more clearly.""In terms of what needs to be improved, I would say better load balancing and data filtering."

Pricing and Cost Advice
  • "The price for Firepower is more expensive than FortiGate. The licensing is very complex. We usually ask for help from Solutel because of its complexity. I have a Cisco account where I can download the VPN client, then connect. Instead, I create an issue with Solutel, then Solutel solves the case."
  • "I know that licensing for some of the advanced solutions, like Intrusion Prevention and Secure Malware Analytics, are nominal costs."
  • "It is affordable. The hardware is not that expensive anymore. It is a matter of licensing these days."
  • "Cisco is not for a small mom-and-pop shop because of the cost, but if you're in a regulated industry where a breach could cost you a million dollars, it's a bargain."
  • "I like the Smart Licensing, because it is more dynamic and easier to keep track of where you are at. If we have a high availability firewall pair and they are deployed in active/standby rather than active/active, I would expect that we would only pay for one set of licenses because you are using only one firewall at any one time. The other is there just for resiliency. The licensing, from a Firepower perspective, still requires you to have two licenses, even if the firewalls are in active/standby, which means that you pay for the two licenses, even though you might only be using one firewall any one time. This is probably not the best way to do it and doesn't represent the best value for money. This could be looked at to see if it could be done in a fairer way."
  • "We are happy with its price. Licensing is on a yearly basis for technical support. There is one license for technical support. There is another license for IP Version 2 VPN and IPS."
  • "I am happy with the product in general, including the pricing."
  • "Their pricing is very aggressive and good. Even a small company can afford it. I am happy with its pricing. Its licensing is on a yearly basis."
  • More Cisco Secure Firewall Pricing and Cost Advice →

  • "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."
  • "I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."
  • More OPNsense Pricing and Cost Advice →

  • "The price is fair."
  • "The license that we purchased is good for three years."
  • "Its price is very high, which makes it difficult to convince the clients to buy this solution."
  • "The price is fair for the solution for the quality you receive."
  • "You need to purchase multiple licenses to manage multiple devices which is cost-prohibitive for the value you would receive."
  • "Customers are required to pay for a yearly subscription."
  • "It has a yearly subscription."
  • "It is a bit expensive. We have to purchase the license and the reporting part separately, which makes it a bit pricey. This is the main reason why we have thought of moving to another firewall. It would be good if they combine both of these."

      Reviews from Real Users

      OPNsense is a favorite security solution among reviewers for a number of reasons. Two of those reasons include the user-friendliness of the solution, which makes it easy to use, and its ability to easily scale.

      For many, a user-friendly solution is essential. FiorindoDi A., a system administration specialist at a tech vendor, says, "The graphic user interface is very good and it is user-friendly, which makes the product easy-to-use."

      Peerspot reviewers speak of the scalability of the solution. For example, an anonymous cloud and infrastructure manager at a venture capital and private equity firm reviewer notes, "OPNsense is easy to scale when running on the hardware."
