The primary use case is to protect all of the internal users from cyber attacks.
The most valuable feature is the user-friendly navigation.
As compared to other firewalls, they should provide an unlimited number of users for the SSL VPN.
The VPN that is available in the new version is a bit bulky and slower in speed. It should also be easier to use.
The SD-WAN feature should be enhanced, similar to Fortinet FortiGate.
I have been working with this solution for six months.
We have just upgraded TZ to 350.
We are not able to use the VPN. It has limitations. It comes with a certain number of users and we have to spend a lot for VPN accessibility.
The technical support is not very good. There is a facility called Geofencing where you can block IP addresses or certain countries.
When contacting their technical support, the technical support said that such a facility is not available in this firewall.
Another issue we had with technical support was when we wanted all of our VPN users to be migrated from our old firewall to this firewall, but somehow, technically they failed to do it. We had to configure it manually.
The technical competency of technical support is a bit on the lower side.
The initial setup was straightforward.
We have two engineers to maintain and deploy this solution.
If it is used for internal users, it is very good as a firewall. But if it has to be used for VPN, it will be a bit costly and the VPN may be bulky.
Using the VPN is not recommended, but as a firewall for blocking threats, it's good.
I would rate SonicWall TZ a seven out of ten.
