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

"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."
"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 the solution are the antivirus and child protection features."
"The most valuable aspect for me is the user-friendly interface."
"The password thing is very good, and the overall URL protection."
"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."
"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"What I like most about Zscaler Web Security is that we can have our users protected from internet threats and viruses even when they're not connected to our network."
"The security is excellent."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"The solution is scalable and stable."
"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."
"Overall, we're very happy with our product."
"Zscaler is an expensive solution, but it's worth the price."
"The solution’s customer service is good."
 

Cons

"I believe the absence of a procedure is the main issue."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"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."
"There is room for improvement in terms of the pricing."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"There are some performance issues when we add on additional controls."
"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."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"Zscaler is one solution. It's a good solution, but it doesn't do everything."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"Cloud App’s database should be improved."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
 

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."
"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."
"It is 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."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"If we need any extra features, the price will increase."
"The pricing is fair based on its competitive market."
"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."
"We have found the solution to be expensive."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"The price of Zscaler Internet Access should improve, it is expensive."
"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 an issue. It is expensive compared to other firewalls on the market."
