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 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."
"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."
"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 features of this solution are its ease of use and operation efficiency."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
"We have seen an ROI; this is a well published product, and you get value for your money."
"The most valuable feature is the ability to drop packets."
"Zscaler offers a centralized DLP solution for web, endpoint, and email."
"I would recommend Zscaler Internet Access due to its ease of use and deployment, with a user-friendly interface."
"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."
"Zscaler Internet Access gives visibility, which is important to have, and the fact that it is usable everywhere is a significant advantage."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
 

Cons

"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."
"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."
"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 customer support of the product is an area with shortcomings where improvements are required."
"There are some performance issues when we add on additional controls."
"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."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
"The interface for administration could be better. They should upgrade the management portal."
"It also needs better integration with other applications as well. There are some restrictions."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
 

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 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."
"It is 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."
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"The price is competitive. It's not cheap and it's not expensive."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"It is a few pounds per user per month."
"It is costlier than other solutions."
"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."
