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.

Quotes from Members

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

Pros

"I would recommend it to others as it's easy to use."
"The password thing is very good, and the overall URL protection."
"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."
"The most valuable aspect for me is the user-friendly interface."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"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 features of this solution are its ease of use and operation efficiency."
"The solution offers a distributed organization to master and to control all of the endpoints."
"Basically, the standard traditional model of a firewall becomes obsolete when you implement Zscaler."
"The most valuable feature is bandwidth control."
"The solution is stable and reliable."
"Zscaler has helped to reduce the time we spend managing security policies, significantly lowered the number of FTEs needed to manage the environment, and has definitely helped reduce the number of infected devices in our organization by proactively preventing attacks."
"​After a proper implementation, the maintenance is very low.​"
"We don't have to buy equipment to use it. And when our engineers set it up on our side, we just configured a few settings and we were in."
"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."
 

Cons

"There is room for improvement in terms of the pricing."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"I believe the absence of a procedure is the main issue."
"The customer support of the product is an area with shortcomings where improvements are required."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"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."
"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."
"We did hit a problem a while back where they didn't scale properly and we had some major issues."
"One thing that they could improve is the ability to import rules from other platforms."
"The DLP part is quite crucial for this particular region."
"The OS capabilities and WSL support could be improved."
"The interface for administration could be better. They should upgrade the management portal."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"The current reports can, therefore, be somewhat improved and simplified."
 

Pricing and Cost Advice

"I would rate the pricing a seven out of ten, with ten being very expensive and one being cheap. It's neither too cheap nor too expensive."
"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."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"The pricing for Zscaler Internet Access could be made cheaper."
"It is a few pounds per user per month."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"Zscaler is transparent about its pricing model."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"There are multiple bundles: enterprise, business, and transformation. Transformation includes all the features, but recently I've seen a few more line items that are additional costs. Overall, it's expensive."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"Our monthly fee is around R3000."
