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."
"Gajshiled's enterprise cloud and DLP-level features give it an advantage over other products."
"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."
"It is a stable solution."
"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."
"If people are looking for a good solution that is priced well this solution is best."
"The solution's outcome is very high, and we often use it in a very high-traffic environment."
"I feel that its valuable features are that it is simple and free."
"The most valuable features in OPNsense are reporting and visibility."
"We saved up to half a million Egyptian pounds, which is nearly $100,000 yearly on licensing or subscription using this kind of software, and the network attacks reduced by approximately 60% after using that, even without customizing the custom configuration yet."
"YouTube provides video explanations, and that brings you to speed, instead of sitting down and reading a 200-page document on the product."
"The most valuable features of OPNsense are the GUI and frequent updates."
"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."
"OPNsense is a great tool for problem-solving with a VPN."
"Overall, I would rate OPNsense as nine out of ten."
 

Cons

"The firewall configuration and administration screens could use some improvement."
"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 can improve SD-WAN compatibility at an enterprise cloud level."
"GajShield Next Generation Firewall would be improved with the addition of a load-balancing feature."
"The UI for the administration of the firewall needs a lot of work."
"We raised a support ticket, and the project didn't get a proper response. There was a skill issue in TAC support."
"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."
"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 user interface could be improved, and the DNS section should be more intuitive."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"The solution would not be suitable for anything large-scale."
"The logging could improve in OPNsense."
"To use Intrusion detection and Antivirus Plugin it is necessary to configure proxy; without a proxy, you cannot use the ClamAV antivirus plugin."
"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 documentation should be clearer because I faced some difficulties navigating many options."
