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 features of the solution are the antivirus and child protection features."
"The most valuable features of this solution are its ease of use and operation efficiency."
"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 feature of Kaspersky Security for Internet Gateway is the antivirus."
"I would recommend it to others as it's easy to use."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"The password thing is very good, and the overall URL protection."
"In summary, this is a good product and I completely recommend it."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote, so I have greater control site access and I minimize the number of compromises that we experience to almost none."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"Zscaler covers all the features needed to replace a VPN or proxy solution; they are good, and they've been on the market for 15 years now, so they are mature enough."
"The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go."
"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."
"It's easy to deploy and easy to use."
 

Cons

"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."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"There is room for improvement in terms of the pricing."
"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."
"When I do a configuration, I do not know what implication it will have downstream."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."
"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."
"Technical support could be better."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"Zscaler Internet Access could improve by adding a VPN feature."
"For the stability of Zscaler Internet Access, I would recommend it, but for the price, I think it's too expensive."
 

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."
"It is expensive."
"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."
"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."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"It is costlier than other solutions."
"The tool is moderately priced."
"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."
"It is a few pounds per user per month."
"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."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
