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

"The most valuable aspect for me is the user-friendly interface."
"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 the solution are the antivirus and child protection features."
"I would recommend it to others as it's easy to use."
"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"The password thing is very good, and the overall URL protection."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"The most valuable features of this solution are its ease of use and operation efficiency."
"Since this is a cloud based product, we don't have to bother about the hardware or physical status and space."
"The protection is most valuable."
"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
"Zscaler is an expensive solution, but it's worth the price."
"The cloud proxy and integration are some of the key features. Since there is cloud waste, we can quickly provision it and start working on the configuration. On top of that, they have added a few more features. They have integrated CASB, and file sandboxing is part of it."
"The solution is scalable, we have around 70,000 total users across various environments."
 

Cons

"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"There is room for improvement in terms of the pricing."
"The customer support of the product is an area with shortcomings where improvements are required."
"When I do a configuration, I do not know what implication it will have downstream."
"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."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"The admin UI and documentation for Zscaler Internet Access could be more intuitive for new users, specifically during initial rollout and advanced policy design."
"There are some performance issues when we add on additional controls."
"It also needs better integration with other applications as well. There are some restrictions."
"The DLP part is quite crucial for this particular region."
"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."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
 

Pricing and Cost Advice

"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."
"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."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"It is expensive."
"I am okay with the pricing."
"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."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"It is a few pounds per user per month."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"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."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"The price of Zscaler Internet Access should improve, it is expensive."
"The price is competitive. It's not cheap and it's not expensive."
