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.

"Basically, the standard traditional model of a firewall becomes obsolete when you implement Zscaler."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."

Cons

"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."
"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."
"I believe the absence of a procedure is the main issue."
"The customer support of the product is an area with shortcomings where improvements are required."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"We'd like to have more plugins and integration."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"We did hit a problem a while back where they didn't scale properly and we had some major issues."
"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
 

Pricing and Cost Advice

"I am okay with the pricing."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"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."
"It is 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."
"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."
"It is a few pounds per user per month."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"Our monthly fee is around R3000."
"The price of Zscaler Internet Access should improve, it is expensive."
"The pricing for Zscaler Internet Access could be made cheaper."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"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."
