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

"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"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 most valuable features of this solution are its ease of use and operation efficiency."
"The most valuable features of the solution are the antivirus and child protection features."
"The password thing is very good, and the overall URL protection."
"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."
"Zscaler offers a centralized DLP solution for web, endpoint, and email."
"Zscaler has helped protect our employees wherever they are working, by delivering safe web access."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"The URL filtering has been the most valuable feature."
"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."
"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."
"The policies are very intuitive and easy to configure, with very little possibility of messing things up."
"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
 

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."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"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."
"Sometimes, support isn't available."
"Cloud App’s database should be improved."
"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."
"I would like to see more training and video documentation."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"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."
"I believe, when you use Zscaler, you are not protected from all malware and malicious attacks, so you may need another tool just to cover these gaps."
"We did hit a problem a while back where they didn't scale properly and we had some major issues."
 

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."
"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."
"I am okay with the pricing."
"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."
"It is costlier than other solutions."
"Our monthly fee is around R3000."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"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."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"The pricing is fair based on its competitive market."
"Zscaler is an expensive solution, but it's worth the price. Their services are unmatched by competitors. Some may come with half the features that Zscaler can offer and be much cheaper. However, they do not have the global coverage that Zscaler has, and they will not provide the same low latencies and the same speeds that Zscaler can."
