"It's an easy solution to set up."
"The most valuable features are the possibility of having one fabric for switching on security."
"FortiGate has a strong security topic which allows all of the Fortinet devices to communicate and share information which makes their security more powerful."
"The CLI is robust and powerful, enabling rapid, consistent changes via SSH."
"It enables our organization to become more productive. Also, it protects our NEtWare from viruses and malware."
"The ease of setting the solution up is a valuable aspect for us."
"I think that the UTM features are the most value, as it truly protects my infrastructure."
"OPNsense is easy to scale when running on the hardware."
"The solution is good for a basic firewall for a small business or for home use."
"OPNsense is highly stable."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."
"OPNsense is easy to use and open source."
"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 most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"The policies are very intuitive and easy to configure, with very little possibility of messing things up."
"The solution’s customer service is good."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"It is easy to set up the solution."
"SSL inspection is a valuable feature."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
"The cloud proxy and integration are some of the key features. Since there is cloud waste, we can quickly provision it and start working on the configuration. On top of that, they have added a few more features. They have integrated CASB, and file sandboxing is part of it."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"We would like to have the ability to disable some of the security functionalities."
"The process of configuring firewall rules appears excessively complex."
"The setup is pretty complex and not easy to implement."
"Their software support needs improvement. I would prefer to have better support for bug fixes. Sometimes, we open a ticket, and it is very difficult to get a solution. Specifically, we are not at all happy with their support for load balancing."
"In the future, I would like to see improvements made to cloud-based management."
"Quality control on their firmware versions needs improvement. When they introduce new firmware, there tend to be bugs."
"I feel that the reporting needs to be improved."
"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."
"I would like better documentation concerning the provided packages and their integration."
"The solution could be more secure."
"There are issues with stability and reliability."
"The interface needs to be simplified. It is not user-friendly."
"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."
"There should be more technical documentation."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"You will need additional training before you can actually start to use it."
"Currently, the solution's interface is not that user-friendly."
"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"Sometimes it's not easy to use during large deployments of workstations."
"When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. "
"They should enhance the audit reporting feature."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
