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 feature of Kaspersky Security for Internet Gateway is the antivirus."
"The most valuable aspect for me is the user-friendly interface."
"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."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."
"The password thing is very good, and the overall URL protection."
"I would recommend it to others as it's easy to use."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"The solution's most valuable features are its reliability and availability, measured by the number of ports it offers."
"Tech support is good."
"The most valuable features of Zscaler Internet Access include its capacity to scale, the security implementation capabilities, the ability to integrate public IPs related to clients so traffic presents on the internet as a client, and the facility to interoperate with SSEs while maintaining the same security mechanisms from on-premises to cloud environments."
"The solution is stable."
"I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
 

Cons

"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 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."
"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."
"There is room for improvement in terms of the pricing."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"It also needs better integration with other applications as well. There are some restrictions."
"The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas."
"We'd like for them to include some sort of antivirus tool."
"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."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"The admin UI and documentation for Zscaler Internet Access could be more intuitive for new users, specifically during initial rollout and advanced policy design."
"An improvement would be if they could provide an out-of-the-box experience, like 20 to 30 features all ready to go. In comparison, LogRhythm offers out-of-the-box features. With Zscaler Internet Access, there is firewall IPS, multiple security services, filtering, DLP, and CASB browser isolation. These are things that all users are going to be using. However, when an administrator or architect would start building this, I would definitely need to engage professional services to help clients do it."
 

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."
"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."
"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 rate the product's price an eight on a scale of one to ten, where one is very cheap, and ten is very expensive."
"It is 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).​"
"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."
"The price of Zscaler Internet Access should improve, it is expensive."
"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."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"If we need any extra features, the price will increase."
"We have found the solution to be expensive."
