885,376 professionals have used our research since 2012.
What do I think about the stability of the solution?
The solution is not perfect and things can go wrong but it is stable. In the last two years that I've been working with it, we did experience a small outage for a group of customers in a particular region for a few hours. Those customers all received service credits for the outage and it was fixed quickly. I give the stability a nine out of ten.
What do I think about the scalability of the solution?
The scalability is perfect. I would give it a ten out of ten.
How are customer service and support?
Customer service and support are good but there is always room for improvement. We do a lot of our own technical support so we don't have a need to call them often. When customer service and support are needed they are usually there. I give them an eight out of ten.
How was the initial setup?
The setup is straightforward. If a customer orders all of the features there is a lot of configuration work to do, or they can choose to leave the features in the standard setup. We recommend they take a few days with one of our consultants who are familiar with the solution so they can point them in the right direction. The configuration is based on individual requirements.
What about the implementation team?
The implementation was done in-house, using one of our engineers.
What was our ROI?
The ROI of the solution is excellent. I give it a ten out of ten.
What's my experience with pricing, setup cost, and licensing?
The solution replaces multiple vendor technologies with one which makes it worth the cost. It is a few pounds per user per month. Occasionally a customer will kick back because they believe it is too expensive for them.
What other advice do I have?
I give the solution a nine out of ten.
Although the solution is easy to configure, there is good value in spending two or three days with an expert that can save a lot of time and effort setting things up in order for you to get real value out of it quickly.
Which deployment model are you using for this solution?
Private Cloud

There is a virtual application in your private data centers that detects the applications, and you can control access.
Pros and Cons
- "Zscaler covers all the features needed to replace a VPN or proxy solution. They are good. They've been on the market for 15 years now, so they are mature enough."
- "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."
- "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 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."
What is our primary use case?
One of the use cases is VPN replacement. Zscaler Private Access replaces the VPN solution.
What is most valuable?
Zscaler covers all the features needed to replace a VPN or proxy solution. They are good. They've been on the market for 15 years now, so they are mature enough.
What needs improvement?
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.
For how long have I used the solution?
We have been building our competency and trying to sell Zscaler to customers for almost two years. We are doing this in our labs also, and we have one customer now.
What do I think about the stability of the solution?
Zscaler is scalable.
What do I think about the scalability of the solution?
Zscaler is a cloud-based solution, so it's scalable.
How are customer service and support?
We worked with Zscaler support initially for some professional services. That service was excellent, but later we had to wait for them to make some changes, so that could be tricky. I rate Zscaler support seven out of 10.
How would you rate customer service and support?
Neutral
How was the initial setup?
Deploying Zscaler is quick and straightforward. You can easily onboard end-users to Zscaler Private Access once you deploy the application. There is a virtual application in your private data centers that detects the applications, and you can control access.
We have two or three engineer to deploy the solution. Two are usually needed because there are different roles from a backup point of view, and we have a different set of people during the design stage. We need some people who understand identity solutions. We have a combination of two or three engineers who normally do deployment for around 1,500 users. One person is usually more than sufficient for maintenance because we don't get that many inquiries unless some changes are needed.
What was our ROI?
We work on a business case, not on ROI, so if the customer sees a positive savings on their business case after the five years or six years, they normally go for Zscaler.
What's my experience with pricing, setup cost, and licensing?
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. It's about 20 to 30 percent costlier than the traditional solution, but it gives you the flexibility to work from anywhere, and everything becomes effortless.
What other advice do I have?
I rate Zscaler Internet Access eight out of 10.
Which deployment model are you using for this solution?

Provides another layer of protection when a user goes to the Internet to browse or download something
Pros and Cons
- "Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."
- "Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week."
- "They could provide more time for the onboarding the training of an IT person."
- "They could provide more time for the onboarding the training of an IT person."
What is our primary use case?
We have Windows 10 laptops. We wanted help securing our laptops for remote work, but we don't have the server for this infrastructure. Whereas, with this solution, the cloud server is managed by Zscaler.
It is a pretty lean solution. We only need to manage the agent and some very small tools on the laptops.
How has it helped my organization?
Currently, we have an on-premise firewall. However, most of the time, users are not working in the office. Therefore, we need to use something, like a Secure Access Service Edge (SASE), to help users. So, we are trying to protect users without a corporate firewall.
We just wanted laptops to have more secure features to help users and protect the company's data. There are two major things deployed on our laptops: Zscaler Internet Access and endpoint detection response (EDR).
Zscaler Internet Access has helped enable our digital transformation.
What is most valuable?
When you try to access suspicious websites, they will give you a warning. This helps us with user access without our office network.
Its cyberthreat protection is important for our needs. We use it for Internet access control, e.g., accessing web pages. We also use it when a user downloads or uploads files from the Internet.
When a user goes to the Internet to browse or download something, it is secured by this tool. This is important to us because it is another layer of protection.
What needs improvement?
They could provide more time for the onboarding the training of an IT person.
We did run into some compatibility issues. We just needed to test its configurations on the web portal and that detected the issues.
For how long have I used the solution?
I have been using it for half a year.
What do I think about the stability of the solution?
We haven't had any issues with stability.
No maintenance is required.
What do I think about the scalability of the solution?
We have 120 users. We have never tested it to go above 1,000 users. It shouldn't have problems because it is an agent working on the laptops using a centralized online server.
How are customer service and support?
The technical support is very good. We create a ticket every week or two.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We didn't have an Internet access control solution previously, only anti-malware for endpoint protection.
Our legacy systems only protected our on-premise network.
How was the initial setup?
The initial setup was straightforward. It took about three days to set up.
What was our ROI?
Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team.
Versus deploying and managing traditional network security hardware, the solution has saved us about four hours a week.
The solution has helped us reduce the number of infected devices in our organization by proactively preventing attacks because some users were unaware of some malware sites.
Which other solutions did I evaluate?
We evaluated two or three different vendors, but finally selected Zscaler Internet Access due to its reputation. Also, the GUI for Zscaler Internet Access was very clear when we tested it.
What other advice do I have?
We are not using the solution for data loss prevention.
When you select this product, test it with other tools running on your machine to ensure there are no compatibility issues between different products.
I would rate it as nine out of 10.

Provides quick access to cloud services, securing our data and allowing us to inspect all our traffic
Pros and Cons
- "The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go."
- "The main benefit that we have seen is performance improvements based on not having to backhaul traffic and getting cloud services closer to the user."
- "One thing that they could improve is the ability to import rules from other platforms."
- "One thing that they could improve is the ability to import rules from other platforms."
What is our primary use case?
The product is an Internet proxy solution. We use it to manage our users' Internet access, making sure that they don't go to the wrong site. We also use it for data loss prevention.
How has it helped my organization?
The main benefit that we have seen is performance improvements based on not having to backhaul traffic and getting cloud services closer to the user.
It provides a modern, cloud-first model. It allows the users quick access to the cloud, depending on where they are in the world. We have users all over the world who access cloud services in their native regions. Previously, we had to backhaul the traffic to our data centers somewhere in the world, then go back to that region. Now, we don't have to do that. A user and data stays within that region. There is no latency there.
It allows us to inspect all our traffic, including SSLs. This is extremely important because most sites use SSLs nowadays. Putting non-SSL inspected data directly into the source would mean that there is a potential for data loss.
Protecting our customers' data is our number one priority. The data loss prevention rules that we have in place make sure that there is nothing within the packets relevant to our customers.
What is most valuable?
The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go.
The cloud-native proxy architecture certainly seems fast enough. The performance is good. The multi-country nature of it allows us to keep the proxy closer to the user so a user's data doesn't transit as far as it would otherwise. It helps to keep latency down and the speed up. It also helps a little bit with cyber threats, but that is not necessarily its primary purpose for us.
Zscaler is constantly improving the network. They are adding new data centers and regions all the time. They listen to feedback, and based on where we tell them to go and put data centers, they add new data centers. For example, they created a couple of data centers in the Middle East, which has been very helpful for us.
What needs improvement?
One thing that they could improve is the ability to import rules from other platforms.
For how long have I used the solution?
We have been using it for slightly more than a year.
What do I think about the stability of the solution?
Its stability is first-class. We haven't had any issues during the time that we have been using it.
What do I think about the scalability of the solution?
It certainly scales to what we have asked it to do so far. We have over 50,000 users on it without a single problem.
How are customer service and support?
From a technical support perspective, when we leave a ticket, the time it takes for them to close the ticket is very fast. Their resolution time is exceptional.
I would rate Zscaler Professional Services and technical support as eight out of 10. I am dropping two points because of some blanks in the time zone support.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We are using it with 20% to 25% of our business at the moment. We are migrating to it from our previous legacy platform.
It adds an alternate layer of protection. We were already using a very powerful tool to do this, but that tool wasn't quite as fast and smart.
How was the initial setup?
It was very complex, but there was training provided by Zscaler. That was very good for understanding it thoroughly. It was complex because we had to make sure that all our rules from previous platforms were migrated over so all our users had access to the same things that they had access to in previous models.
We aren't yet fully deployed. We have been at it for about a year and a half. We currently have over 50,000 users deployed and another 120,000 to go.
The only pain points that we have are self-inflicted because of our slow rollout of the product, which is not actually Zscaler's fault.
What about the implementation team?
We had Zscaler Professional Services helping us for quite a long time at the start of the project. They made sure that everything was set up correctly with no holes. They were very good and first-class.
What was our ROI?
So far, it has not saved us on costs as a result of retiring on-premises technology, next-generation firewalls, legacy proxies, or MPLS links. Though, we are expecting it to do that going forward.
What's my experience with pricing, setup cost, and licensing?
I have not been involved with pricing and licensing.
Which other solutions did I evaluate?
We evaluated several solutions.
What other advice do I have?
Try it, test it out, and make sure it works for you. It is not going to work for everybody because it is not a zero-cost solution. However, it does provide significant benefits in terms of its latency and capability to inspect your traffic as well as keeping your customer data secure.
It hasn't saved us time as compared to deploying and managing traditional network security hardware because we already had everything in place from a traditional standpoint. We take security very seriously. Security is paramount to what we do. We cannot, under any circumstances, allow our customers' data to be compromised. So, we have all the correct things in place from a traditional standpoint. We are now modernizing, and Zscaler Internet Access allows us to do that. However, we will not compromise at all. We have to move slowly to it.
It has not reduced the time that we spend managing security policies. The security policies used on Zscaler Internet Access are the same ones that we used with our previous technologies.
It has not really reduced the number of infected devices in our organization because we already had preventions in place with other technologies. We didn't previously have any infections.
I would rate Zscaler Internet Access as nine out of 10. It is a very good solution.
