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

"The password thing is very good, and the overall URL protection."
"The most valuable aspect for me is the user-friendly interface."
"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."
"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 most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"Basically, the standard traditional model of a firewall becomes obsolete when you implement Zscaler."
"Zscaler is an expensive solution, but it's worth the price."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"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."
"The solution’s customer service is good."
"Zscaler has helped to reduce the time we spend managing security policies, significantly lowered the number of FTEs needed to manage the environment, and has definitely helped reduce the number of infected devices in our organization by proactively preventing attacks."
"The security is excellent."
"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."
 

Cons

"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"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."
"The customer support of the product is an area with shortcomings where improvements are required."
"There is room for improvement in terms of the pricing."
"I believe the absence of a procedure is the main issue."
"They should enhance the audit reporting feature."
"One thing that they could improve is the ability to import rules from other platforms."
"Sometimes it's not easy to use during large deployments of workstations. It's a bottleneck from a network point of view."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"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."
"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."
"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."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
 

Pricing and Cost Advice

"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."
"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 transparent about its pricing model."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"The pricing is fair based on its competitive market."
"It is a few pounds per user per month."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"It is quite expensive. It does its job, but it is quite expensive for what we need."
