Cloud data protection has improved and automation reduces manual security tasks
The best features that Zscaler Cloud Firewall offers are that it is AI powered and automated. The automation especially reduces manual tasks as we used to have lots of manual activities for such services. Reporting is very powerful regarding the features of Zscaler Cloud Firewall. Zscaler Cloud Firewall has positively impacted my organization by increasing ROI, especially by reducing costs.

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."
"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."
"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."
"The initial setup is straightforward."
"The technical support from Zscaler was excellent."
"It provides in-depth visibility into your network, ensuring that traffic flowing into your organization, be it from offices or individual users, is effectively filtered and secured through multiple layers of protection."
"It is a stable solution."
"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."
"The product’s firewall and VPN package are fantastic compared to any other solution."
"Zscaler has a good foothold in the market and any new competitor will have to be cognizant of the fact that they will have to be affordable and provide all of the features Zscaler has while being good at threat analysis and filtering."
"The scalability is okay. We have around 2200 people using this solution."
 

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."
"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."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Licensing is not cheap."
"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."
"Currently, the Data Leak Prevention is only for web filtering and there is nothing for email and the USB, so it would be an improvement if that could be included."
"One area for improvement lies in their customer service, which feels less ideal for a premium product. The response and support are sometimes inadequate, which detracts from the overall experience of an otherwise impressive solution."
"If I can get rid of Jetscaler, I will use Twingate for sure."
"It would be nice to have some sort of a form factor, a physical form factor perhaps, or virtual machine that you could install on devices or on a cloud, and have some cloud computing."
"When it comes to customer support, there is room for improvement in Zscaler's service."
"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."
"The issue right now is probably that Zscaler is not providing web browser isolation."
 

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 product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight out of ten."
"There are licensing costs, and I would not say that it's a cheap vendor."
"It is not the most budget-friendly solution, but it's important to consider its overall value."
"It is expensive for small businesses."
"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
"There are different subscription models available."
