Senior Network Security Engineer at UNITE HERE HEALTH
Simplifies the management of complex data networks, but its technical support could be improved
Sometimes, we have to use SD-WAN support for the solution, which can be improved by adapting some features that will help our approach to network services. The solution can adapt some of the tools where we, as network engineers, can adjust to the changing application needs. Also, the solution can provide us with multiple support, allowing us to create a network segment. The solution’s technical support could be improved.

Open-source firewall has provided affordable real-time protection and secure remote access
In my opinion, OPNsense could improve by incorporating either an open side of wireless management or a way that you can also manage your interconnected devices. You could easily have SNMP, Simple Network Management Protocol, incorporated in it so that you can easily manage the devices and easily get the information about the devices that you are managing. Additionally, the inclusion of Pi-hole would allow you to create an ad-free network instead of adding it on a separate device. I would prefer that incorporated into OPNsense, or if it is there, I would appreciate guidance on how to use it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is an easily scalable solution...The initial setup was very easy."
"The most valuable feature of the GajShield Next Generation Firewall is the user-friendly settings, dashboards, and anti-threat protection. Additionally, the solution upgrades frequently which is good because we receive new features."
"The solution's outcome is very high, and we often use it in a very high-traffic environment."
"It is a stable solution."
"Once it is configured, it is very stable, and we don't get any calls from our clients unless they have some specific requirement, like port forwarding or something."
"GajShield has improved our mobile device-based connectivity."
"GajShield Next Generation Firewall's best feature is the network DLP."
"If people are looking for a good solution that is priced well this solution is best."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"We have found pretty much all the features of the solution to be valuable."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"Offering this solution has provided some of our clients with firewall protection and UTM, which basically just protects them from the internet."
"The solution has high availability."
"It has an open license. It works very well, and there is an update every month."
"We have been operating here in our lab for several months, and everything appears to be extremely stable."
"The solution is very user-friendly, easy to manage and deploy, and is good for a basic firewall for a small business or for home use."
 

Cons

"The firewall configuration and administration screens could use some improvement."
"Sometimes, we have to use SD-WAN support for the solution, which can be improved by adapting some features that will help our approach to network services."
"We face issues with some configuration parts that we don't understand in the solution, and sometimes we face issues with the VPN connection."
"GajShield Next Generation Firewall would be improved with the addition of a load-balancing feature."
"GajShield Next Generation Firewall could improve the flow of the settings. If somebody's using a Cisco firewall or any other brand and they want to use GajShield Next Generation Firewall the platform's UI is a bit different. If it was more similar to the others it would be better."
"The UI for the administration of the firewall needs a lot of work."
"Gajshield can improve SD-WAN compatibility at an enterprise cloud level."
"We raised a support ticket, and the project didn't get a proper response. There was a skill issue in TAC support."
"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 interface needs to be simplified. It is not user-friendly."
"There should be more technical documentation."
"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."
"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 reporting part could be better."
"I confirm that I am currently still working with OPNsense and still using their product. However, because of the hardware that I am using, sometimes it ends up freezing quite often, especially the interfaces, most of the busy interfaces."
"The documentation should be clearer because I faced some difficulties navigating many options."
 

Pricing and Cost Advice

"GajShield Next Generation Firewall is not that expensive, and its pricing is better than Palo Alto."
"GajShield is a cheaper solution as of now. The subscription is yearly."
"GajShield Next Generation Firewall is reasonably priced."
"GajShield Next Generation Firewall is cheaper than the other products in the market. The licensing costs for the solution are on a yearly basis."
"It was about 15% cheaper compared to Sophos."
"The price of the GajShield Next Generation Firewall is very attractive when compared to other solutions."
"The price of OPNsense is good."
"As an appliance, it's in the medium price range."
"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."
"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."
"We are not paying any licensing fees. OPNsense is completely free for us."
"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."
"OPNsense is open source software so at this time it is free for us to use."
"It is free."
