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.

Cloud security has transformed remote access and now supports zero trust for all users
The best features Zscaler Internet Access offers are Secure Web Gateway, URL filtering, SSL inspections, and policy-based access control. I find myself relying on Secure Web Gateway, URL filtering, SSL inspection, and policy-based access control the most because these are the main and top-most features I use regularly. Zscaler Internet Access has all of these types of features for securing all internet access and web inspections, allowing me to control all traffic through these features. Zscaler Internet Access features include a Secure Web Gateway for URL filtering, file type control, and inline SSL inspections. The second feature is a cloud firewall with Layer 3 to Layer 7 filtering control and stateful inspections. No hardware inspection or hardware firewall is required. I can also perform segmentations by users, location, and application. There is a cloud CASB solution available as well. Additionally, there is an advanced threat protection feature with signature-based behavioral detections, inline IPS, and zero-day threat protections. The cloud sandboxing solution scans unknown files and provides machine learning-based verdicts to prevent zero-day malware delivery in my environment. There is also a DNS security feature that provides DNS tunneling detections, malicious domain controls, and faster threat containment at the DNS layer. The data protection feature includes inline DLP and CASB-style cloud app control, data sovereignty enforcement, and browser isolation, which executes risky sites in isolated cloud browsers and prevents endpoint compromises. Zscaler Internet Access has positively impacted my organization by reducing the dependency on on-premises hardware and improving security posture, enabling faster user onboarding, and providing better performance for remote users. It has resulted in a drop in security incidents related to web threats and improved visibility into user activity. An area for improvement includes fine-grained troubleshooting tools, better policy simulations, and optimizations around initial configuration complexity.

Quotes from Members

"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."
"The most valuable aspect for me is the user-friendly interface."
"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 most valuable features of the solution are the antivirus and child protection features."
"The password thing is very good, and the overall URL protection."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"Since this is a cloud based product, we don't have to bother about the hardware or physical status and space."
"Zscaler offers the best service since you are protected wherever you are."
"The most valuable feature of the solution is SWG traffic."
"We don't have to buy equipment to use it. And when our engineers set it up on our side, we just configured a few settings and we were in."
"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."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"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 customer support of the product is an area with shortcomings where improvements are required."
"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."
"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."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP. This is a bit problematic."
"The current reports can, therefore, be somewhat improved and simplified."
"For the stability of Zscaler Internet Access, I would recommend it, but for the price, I think it's too expensive."
"It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
"They could provide more time for the onboarding the training of an IT person."
"The solution is quite expensive. It's around double what others are offering."
"The interface for administration could be better. They should upgrade the management portal."
 

Pricing and Cost Advice

"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."
"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 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 cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"I am okay with the pricing."
"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."
"The price is competitive. It's not cheap and it's not expensive."
"The pricing is fair based on its competitive market."
"If we need any extra features, the price will increase."
"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 pricing for Zscaler Internet Access could be made cheaper."
"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."
"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."
