Featured Zyxel Unified Security Gateway reviews

It Manager at Diamond Braces

Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

The product's most beneficial feature is its ability to adapt to and deal with all malware attacks. The intrusion detection capabilities I need are present in the solution. The tool has impacted the security posture in our organization since it has antivirus, anti-spam, web filters, security and quality control. The enhancement in the security posture has been beneficial for my company. Integrating Zyxel Unified Security Gateway with our company's existing network infrastructure has been good as it works fine and I haven't seen any issues in it till now. The vendor takes care of the maintenance part of the solution. I recommend the product to those who plan to use it. I rate the tool a six out of ten.
