Advanced security filters have blocked threats and protect our users’ web and application access
SonicWall TZ gives us multiple features, such as Content Filter, Application Filter, ATP, IPS policy, Geo-Filter, Botnet filter, and many more. I use Content Filter with SonicWall TZ most of the time because we need to create a policy on behalf of the content filter to track who is using what. If we want to block any types of websites for any specific user, we can do it from the firewall. SonicWall TZ has multiple features, such as Application Filter as well. SonicWall TZ has impacted our organization positively because it stops all threats. If any types of malware signature or any types of bad behavior malware appear, it prevents them.

Quotes from Members

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

Pros

"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"Hillstone supports IOT setup and detecting intrusions from IOT or CCTV connectivity, and with this solution, we can also detect unauthorized devices plugged into the CCTV network and sound the alarm to the administrator."
"We found some limitations with Fortinet FortiGate, and we are satisfied with Hillstone T-Series right now."
"It has been stable so far."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"SonicWall TZ is a very cost-effective solution that provides good security."
"I have found the stability of this product to be excellent."
"This is a product that we recommend, and also suggest that people upgrade their old devices to this model."
"SonicWall provides each location with its own security and provides our company with the ability to centralize our servers so they can provide applications to all the locations and users."
"The features that we have found most valuable in SonicWall TZ are the intrusion and brute force attack prevention."
"We like the unified threat management for defense-in-depth. We can terminate our site-to-site and remote access VPNs with it."
"The MSSP partnership program is valuable, but is still too expensive."
"It does exactly what it says on the tin, is good for protecting the business from being compromised, and its port protection is very good."
 

Cons

"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Licensing is not cheap, but there are customers who will buy because they understand that this has a cost involved and they will cater their budget for that."
"Licensing is not cheap."
"The solution's pricing could be made cheaper."
"I currently have two of the issues from SonicWall. One issue is that the IP is not the public IP. Sometimes it moves to an alternate source and I have to refresh the new IP then we can go on."
"Sometimes there are issues."
"I would like to see lower antivirus pricing."
"We would like to improve the rules configuration in SonicWall TZ. Sometimes the rules don't work."
"We have experienced some issues with SonicWall TZ and they are lacking some advanced features other vendors have."
"The areas we would like to see improvement include more features available similar to the equivalent FortiGate appliance, e.g. SSL encryption and inspection. Two-factor authentication capability would be another additional feature that could be included in the next release."
"FortiGate has a client DNS in the firewall, but SonicWall doesn't have that."
 

Pricing and Cost Advice

"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"We got a much cheaper price than that provided by Fortinet right now."
"The license that we purchased is good for three years."
"The product pricing is justified for the features provided."
"It is an expensive solution compared to one of its competitors."
"The prices are expensive."
"Licensing costs have been around $2,000. There are no other costs above the standard licensing fees."
"We have to pay yearly. Its licensing can be improved, and they should provide more features, such as AV, email filtering, and so on with the basic subscription."
"SonicWall has authorized distributors in our country. They have about two or three distributors in the country, so it makes it a bit easier. What we do is to request a quotation from these distributors, then we do a value for money analysis and see which one of them is giving us a competitive price."
"The firewall with the servers costs about 80 pounds a month. We get the device, and it is replaced every two or three years."
