The interface is easy to understand, so when there are threats you get alerts. It's quite intuitive, but if you are ever confused they have instructional videos. For example, if you don't understand a graph there's a link to a video that explains what the graph means. It makes it very user-friendly.

The solution is good, but they have poor marketing in Nigeria. They need to market their product better.

The signature discs, compared to Palo Alto, aren't as good. It takes more time to get the signature updates.

The support is not very good, but the product is stable so it is not so much of a problem.
MT
Network and Security Engineer at Neurones
Aug 25, 2019
In terms of what needs improvements, the troubleshooting could use improvement. When we work with other products like Cisco ASA, Palo Alto, and Check Point, we see a big difference in the troubleshooting. It's not easy to find a report.

For me, it is important to be able to block VPN applications, like Facebook, so I would like to see that included in the next release. With this version, if you want to block or allow a site, you now have to drag all the domains related to this site.
