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."
"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."
"The most valuable features of this solution are its ease of use and operation efficiency."
"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 aspect for me is the user-friendly interface."
"The password thing is very good, and the overall URL protection."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"The URL filtering has been the most valuable feature."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"The policies are very intuitive and easy to configure, with very little possibility of messing things up."
"The main benefit that we have seen is performance improvements based on not having to backhaul traffic and getting cloud services closer to the user."
"In summary, this is a good product and I completely recommend it."
"My advice for people looking into implementing Zscaler Internet Access is that it's quite stable."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
 

Cons

"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."
"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."
"I believe the absence of a procedure is the main issue."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"We use other similar products and find them to be a bit more preferable to Zscaler."
"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."
"The solution is expensive. They recently revised the pricing and packaging. Some of our existing customers have been asking for alternate solutions for a lower price."
"The OS capabilities and WSL support could be improved."
"The scalability of Zscaler Internet Access rates at 7-8 in the majority of cases. However, I am currently working with a client that requires very high internet throughput, which has been challenging."
"Zscaler needs to add client-to-client communication. It's always client-to-server communication. The cloud and branch connectors could be improved because we're still dependent on traditional firewalls. They should eliminate this. They should also provide WAN devices should to compete with the SD-WAN solutions also."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"Cloud App’s database should be improved."
 

Pricing and Cost Advice

"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."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"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 pricing is an issue. It is expensive compared to other firewalls on the 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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"It is costlier than other solutions."
"The pricing for Zscaler Internet Access could be made cheaper."
"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."
