Automated breach prevention has protected critical workloads and keeps external attacks blocked
I am familiar with SonicWall TZ. I have done a POC of TZ but I have not worked extensively with it. I have worked with the 2600 firewall and then the 3600. These are the models which we have worked with.SonicWall NSa was an on-premises solution. The two firewalls which were in production, in the data center and on the LAN side, were both on-premises solutions. We had a pre-decided budget under which we would purchase the firewall. All parameters including security, high availability, and budget concerns were covered with SonicWall NSa being implemented at that time. SonicWall NSa is a user-friendly product that is easy to configure, and it is easy for network personnel and firewall administrators to work with. Even the L1 team captured and learned this firewall effectively, helping us resolve all parameters related to high availability firewalls within budget-friendly costs. I rate this review a nine out of ten.

I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Overall, this is a good firewall and they would do much better in the market if they included support for DynDNS and additional VPN connections for free."
"SonicWall NSa has excellent support."
"The most valuable features of this solution are intrusion detection, intrusion prevention, and the advanced capture client, which provides live traffic analysis."
"We like the features, but the main thing is from a commercial and cost perspective it is very good."
"Anti-Spam reduces unwanted mail on corporate exchange services."
"The functionality is the same whether it is on hardware or a virtual appliance. The interface is the same. It's nice that it's standardized."
"It has a very good user interface."
"Valuable features include a web filter, DHCP, monitoring capabilities, IPsec VPN and other security controls, and integration with the active directory and other security controls such as IPS and IDS."
"The cost is very low."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
"This is a capable appliance and the standard features work well for us."
 

Cons

"Sometimes I found the GUI and some of the features a little bit hard to navigate, as opposed to Fortigate, which is much more user-friendly."
"The support is not up to the mark because the quality is lacking; however, SonicWall has been in the market for a while, so people are aware of its qualities, and being a cost-effective product, it is very good."
"The detection of malware can improve in SonicWall NSa."
"The cloud services may be in need of some improvement."
"We also use the Sophos Firewall for web configuration, which we don't have in SonicWall. Only Sophos has those options. If SonicWall included that feature, that would be a benefit for us."
"It's not as easy to use, as, for example, Palo Alto. Some of the configurations could be better."
"The problem primarily with SonicWall is it's a Unix box. And it's all software, all the activities, blocking, censoring, everything has to happen in the software. If you start hitting the box with a lot of sessions it slows down and that's not what I expect from a firewall."
"The implementation for VLANs is a little bit cumbersome. It would be good to make that a little bit easier."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
"The product has some scalability and data management issues where improvements are required."
"Sometimes it reboots when you least expect it, and that's the main issue."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
 

Pricing and Cost Advice

"SonicWall NSa has reasonable pricing. My company pays for it yearly, but I forgot how much the company pays. From what I remember, you only pay for the license fees."
"Licensed features provide application control, content filtering, antivirus, and anti-malware all in a single appliance."
"SonicWall is not an expensive solution."
"Compared to Fortinet and Cisco, SonicWall NSa is a cheaper solution."
"Normally, when we buy any product, we buy it with a five-year service built into it. Later on, depending on the growth of the organization, we go for a new one or an upgrade."
"Considering the market, I believe that the price of this solution is great."
"Licensing fees are paid on a yearly basis, and we are happy with the pricing."
"We are on a three-year license for the solution. The price is inexpensive compared to other solutions."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
