Effective threat protection with room for cost and usability improvements
There are some drawbacks that I would mention. To be frank, enterprises always look for cost benefits, so Kaspersky could implement some price benefits. Additionally, regarding know-how, if I am an experienced person it's fine, but when someone novice is working with it, they need information about why certain actions are required. Security is a field that is very vast, and implications are not known to everyone. In future updates, a quick walk-through and know-how features would be beneficial, such as information text at relevant places. This will increase usability. Feature-wise, an impact analysis would be a really good addition.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

Pros

"I would recommend it to others as it's easy to use."
"The most valuable aspect for me is the user-friendly interface."
"The password thing is very good, and the overall URL protection."
"The most valuable features of this solution are its ease of use and operation efficiency."
"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."
"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"The most valuable features of the solution are the antivirus and child protection features."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"The solution is stable."
"From the top to bottom, Zscaler Internet Access is a great security product that protects my end users and remote users in the cloud."
"This solution helps you establish a secure connection from your laptop to the closest Zscaler point of presence, so you have protection anywhere in the world."
"The most valuable feature is bandwidth control."
"My advice for people looking into implementing Zscaler Internet Access is that it's quite stable."
"We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
 

Cons

"I believe the absence of a procedure is the main issue."
"When I do a configuration, I do not know what implication it will have downstream."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"The customer support of the product is an area with shortcomings where improvements are required."
"There is room for improvement in terms of the pricing."
"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"With the pricing structure that they currently have, it is only for big customers."
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
"In terms of user experience, it could be better."
"The OS capabilities and WSL support could be improved."
"The tool should improve the predefined dictionaries."
"There are some performance issues when we add on additional controls."
 

Pricing and Cost Advice

"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"I am okay with the pricing."
"Personal computer licenses can be expensive if you were to scale the solution extensively. However, large companies will most likely use Endpoint solutions and not this one."

"It is expensive."
"I rate the product's price an eight on a scale of one to ten, where one is very cheap, and ten is very expensive."
"We have found the solution to be expensive."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"If we need any extra features, the price will increase."
"The price of Zscaler Internet Access should improve, it is expensive."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"The price is competitive. It's not cheap and it's not expensive."
