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 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 the solution are the antivirus and child protection features."
"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."
"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 aspect for me is the user-friendly interface."
"​After a proper implementation, the maintenance is very low.​"
"My advice for people looking into implementing Zscaler Internet Access is that it's quite stable."
"Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income, improved our security environment control and endpoint protection, and it prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses."
"From the top to bottom, Zscaler Internet Access is a great security product that protects my end users and remote users in the cloud."
"The security is excellent."
"Basically, the standard traditional model of a firewall becomes obsolete when you implement Zscaler."
"The solution’s customer service is good."
"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."
 

Cons

"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."
"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."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"The customer support of the product is an area with shortcomings where improvements are required."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"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."
"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."
"They should enhance the audit reporting feature."
"Regarding improvements in Zscaler Internet Access, the admin console can sometimes be slow, particularly when navigating through reports or policy configuration."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
"I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again."
"The solution is quite expensive. It's around double what others are offering."
 

Pricing and Cost Advice

"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."
"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."
"It is expensive."
"The pricing is fair based on its competitive market."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The pricing for Zscaler Internet Access could be made cheaper."
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"Zscaler is transparent about its pricing model."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
