We performed a comparison between OPNsense and Zyxel Unified Security Gateway based on real PeerSpot user reviews.
Find out what your peers are saying about Fortinet, Cisco, Netgate and others in Firewalls."One of the most valuable features is the GUI front end, which is very easy to use. But I'm also a command-line guy, and being able to access the device via command-line for advanced troubleshooting is quite important."
"The whole firewall functionality, including firewall policies and IPS policies, is valuable. It has all kinds of functionalities. It has IPS, VPN, and other features. They are doing quite a lot of stuff with their devices."
"It just works for us."
"Cisco's technical support is the best and that's why everybody implements their products."
"Firepower has reduced our firewall operational costs by about 25 percent."
"I have not contacted technical support. There is a lot of information on the internet for troubleshooting. All you need to do is use a search engine and you will find the information you are looking for easily."
"We find all of its features very useful. Its main features are policies and access lists. We use both of them, and we also use routing."
"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."
"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."
"The system in general is quite flexible."
"It's more secure and more reliable."
"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."
"OPNsense is highly stable."
"OPNsense is easy to scale when running on the hardware."
"What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The solution can scale well."
"Most of the features don't work well, and some features are missing as well."
"I think the ASA layer is thin. It's always Layer 3 or Layer 4 source controller and doesn't control the Layer 7 traffic. It's important, and you'll need an additional firewall."
"The visibility for VPN is one big part. The policy administration could be improved in terms of customizations and flexibility for changing it to our needs."
"On the VPN side, Firepower could be better. It needs more monitoring on VPNs. Right now, it's not that good. You can set up a VPN in Firepower, but you can't monitor it."
"It can be improved when it comes to monitoring. Today, the logs from the firewalls could be improved a bit more without integrating with other devices."
"A feature that would allow me to load balance among multiple ISPs, especially since we have deployed it as a perimeter firewall, would be a great addition."
"One issue with Firepower Management Center is deployment time. It takes seven to 10 minutes and that's a long time for deployment. In that amount of time, management or someone else can ask me to change something or to provide permissions, but during that time, doing so is not possible. It's a drawback with Cisco. Other vendors, like Palo Alto or Fortinet do not have this deployment time issue."
"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."
"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 logging could improve in OPNsense."
"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 IPS solution could be more reliable."
"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."
"Its interface should be a little bit better."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"They should improve IPEs for security in the future."
"Sometimes it reboots when you least expect it, and that's the main issue."
