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

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"I would recommend it to others as it's easy to use."
"The password thing is very good, and the overall URL protection."
"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."
"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."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"The most valuable feature is bandwidth control."
"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"Because it is well integrated and mature, it's faster, cheaper, and better for the company."
"Since this is a cloud based product, we don't have to bother about the hardware or physical status and space."
"Zscaler Internet Access has positively impacted our organization by improving our overall security posture, providing better visibility into the internet traffic our employees access, and protecting users from web-based threats such as phishing websites, malicious downloads, and suspicious sites."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
 

Cons

"There is room for improvement in terms of the pricing."
"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."
"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."
"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 license is per user, and there's a minimum license per user per year. It's costly if you compare it to the traditional solutions like Symantec or Bluecoat."
"Initially there were issues in terms of stability and improved a lot now."
"There are many functionalities in Zscaler Internet Access that need improvements, such as an advanced firewall and logging capabilities to track calls."
"I would like to see more training and video documentation."
"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution."
"One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."
 

Pricing and Cost Advice

"It is expensive."
"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."
"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."
"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."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"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."
"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."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"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."
