We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good.

The most valuable feature of the T-Series is the reports you can customize and generate. What everybody wants from the firewall at the end of the day are the reports they can share with management or whoever.

Hillstone also does what we call "advanced threat detection." Before the threat comes in, you can already detect the threat and they're able to mitigate the threat before it actually comes to the network.

Price wise, Hillstone T-Series is cheaper than Fortinet FortiGate right now.

It has been stable so far.

Also, Hillstone T-Series has a good technical support team.
