851,823 professionals have used our research since 2012.
What do I think about the stability of the solution?
Zscaler Internet Access is quite stable.
What do I think about the scalability of the solution?
I have not had any issues with the scalability of Zscaler Internet Access. I have not encountered scalability issues, but my company has not scaled up that much to encounter problems with scalability, so I can't really comment on how scalable the solution is.
How are customer service and support?
Zscaler Internet Access has good technical support. We have not had an issue where multiple escalations were needed from the support team. The issues were normally quite straightforward and were able to be sorted out with minimum intervention. Whatever support we have requested from Zscaler, we had a very good experience.
How was the initial setup?
The initial setup for Zscaler Internet Access is straightforward. On a scale of one to five, with one being the worst and five being the best, I'm rating my experience with its setup a four.
What's my experience with pricing, setup cost, and licensing?
The pricing for Zscaler Internet Access could be made cheaper.
What other advice do I have?
My advice for people looking into implementing Zscaler Internet Access is that it's quite stable. Its features are quite mature, so I would recommend for people to go for the implementation of the solution.
Zscaler Internet Access is deployed on the cloud, particularly on Zcaler's cloud: the ZIA. It's a SaaS solution.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Senior Product Manager - Cyber Security for Middle East, Central Asia and Africa Region at Ivanti
Provides integrated CASB and file sandboxing but could be less expensive
Pros and Cons
- "The cloud proxy and integration are some of the key features. Since there is cloud waste, we can quickly provision it and start working on the configuration. On top of that, they have added a few more features. They have integrated CASB, and file sandboxing is part of it."
- "The solution is expensive. They recently revised the pricing and packaging. Some of our existing customers have been asking for alternate solutions for a lower price."
What is our primary use case?
We are using the latest version of the solution. It's deployed on a private cloud through Zscaler.
We mostly use this solution in the distributed network where direct internet access has been growing. There are a lot of branches connected with their own internet access, so the solution secures the connectivity at remote locations. There's a very large network with many branches and users working across the globe.
There are about 5,000 people using this solution in my organization. Technical support uses this solution 24/7. We have an operations team and a monitoring and management team.
How has it helped my organization?
This solution helps to protect our network.
What is most valuable?
The cloud proxy and integration are some of the key features. Since there is cloud waste, we can quickly provision it and start working on the configuration. On top of that, they have added a few more features. They have integrated CASB, and file sandboxing is part of it.
We have used this solution for three years. We have seen a lot of traction in the market and a lot of users adopting this solution. We're able to control or manage all the remote locations from one place. When a user is traveling from one location and is connected to the internet, it connects to the bigger cloud and relevant policies will be applied to the user or the device. We have expanded the base from very few users to a large number.
What needs improvement?
The solution is expensive. They recently revised the pricing and packaging. Some of our existing customers have been asking for alternate solutions for a lower price.
For how long have I used the solution?
I have been using this solution for about three years.
What do I think about the stability of the solution?
It's stable.
What do I think about the scalability of the solution?
It's scalable.
How are customer service and support?
Sometimes I feel that the Zscaler team is a bit lacking. The response is slow sometimes.
I would rate technical support three out of five.
How was the initial setup?
Setup isn't complicated.
I would rate setup as four out of five. Setup took a couple of hours because of some of the requirements. It can take up to a month depending on how many policy configurations need to be done and how many users there are.
What about the implementation team?
Deployment was done in-house.
What's my experience with pricing, setup cost, and licensing?
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.
They have standard bundling and additional licensing, which is a high cost.
Which other solutions did I evaluate?
We also evaluated Blue Coat. We have used Forcepoint too, but there were a lot of support challenges. That's why we went with Zscaler.
What other advice do I have?
I would rate this solution as seven out of ten.
The product is pretty good. They are the leader, as far as Gartner Magic Quadrant is concerned. The functionality and bundling are good, but the pricing isn't great. I think Netskope is competition because of their features and better pricing.
The competition offers more flexibility. This is a cloud solution, so a lot of banking customers and government customers are a bit reluctant to use it. Some of the competition has the on-premises model as well. Zscaler could also work on their bundling, packaging, and pricing.
Which deployment model are you using for this solution?
Private Cloud

Server Administration / Security Officer at a manufacturing company with 501-1,000 employees
Delivers safe web access for our remote employees, increasing cybersecurity and saving us time
Pros and Cons
- "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."
- "I would like to see more training and video documentation."
What is our primary use case?
Because some of our employees need to work remotely, due to the COVID-19 pandemic, we were looking for a solution that would keep them safe. We have a Cisco ASA firewall in our company, but when people work remotely they can't be protected by that solution. That's why we decided to go for a WAF.
How has it helped my organization?
Zscaler has helped protect our employees wherever they are working, by delivering safe web access. We are doing the same things that we were always doing at our company, and in the same way, but now we are functioning safely outside of our premises. We were already able to work remotely using the Cisco agent, but the Zscaler agent is an improvement at the cybersecurity level.
Another benefit is that we are not managing all the backend infrastructure and that saves 10 to 15 percent of our time in terms of productivity.
It has also reduced the time we spend managing security policies. That's very important because it means that our engineer can spend time focusing on other business activities. The solution is saving 15 to 20 percent of our engineer's time, per day.
What is most valuable?
Some of the most valuable features are that, as a remote solution it is
- lightweight
- very easy to set up and configure
- the protection is in the cloud.
We are agnostic when it comes to what they are doing. 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.
What needs improvement?
I would like to see more training and video documentation.
For how long have I used the solution?
I've been using Zscaler Internet Access for about two months.
What do I think about the stability of the solution?
It's very stable. We haven't had any issues so far.
What do I think about the scalability of the solution?
The scalability is also very good. We have about 300 users. We gradually want to move all 800 people in our operation over to Zscaler and to remove the local solution.
How are customer service and support?
The technical support we get from them is great. The guys know what they're doing.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
With our legacy system, a VPN solution from Cisco called AnyConnect, we have to buy licenses and equipment, as well as storage in a data center. With this cloud solution, we just pay a fee and it's easy to use. Digital transformation is very important to us because it is a corporate objective. We started with Microsoft 360, and Zscaler is another brick in the wall, in that direction.
We are planning to downgrade our firewall and just keep Zscaler. We're not going to save money with Zscaler, but we are aligning with the corporate objectives by using it.
How was the initial setup?
It's easy to set up. It took my network engineer about one week to prepare the environment, and our software network engineer is the person in charge of keeping it going.
What about the implementation team?
We had a local provider, SISAP, help us. They are a business based in Guatemala, with an office here in Honduras. They worked very well.
What's my experience with pricing, setup cost, and licensing?
The price is competitive. It's not cheap and it's not expensive.
Which other solutions did I evaluate?
We looked at Cisco Umbrella as an option. But because our organization is part of a corporation that was already using Zscaler, we're aligning ourselves with our headquarters' implementation by going with this solution.
What other advice do I have?
Zscaler is a great solution. We have a very good representative here in Honduras and it was easy to set up. It's a very strong solution with the cloud infrastructure that meets our needs and most of the needs of our users. We are very happy with the solution.

IT Project Manager at LifeCell international Pvt.Ltd
Simple to use with easy access and good reliability
Pros and Cons
- "The solution is stable."
- "We'd like for them to include some sort of antivirus tool."
What is our primary use case?
We can use the solution for users that are working from home. It allows us to manage control over security. We install an agent and can set the domains that are allowed on the network. It helps ensure security.
What is most valuable?
It can be easily accessed by the cloud. Users can easily work from home while maintaining company security.
The servers are hosted in the cloud, and it maintains security for Azure. It's like having double security - one for the cloud and one for the user.
It is simple to use. We can create multiple tunnels with ease. It's simpler to use than a VPN.
The solution is stable.
What needs improvement?
We'd like for them to include some sort of antivirus tool. It would help if that came bundled with this product from a security standpoint.
We'd like to have a server connector without ht need for multiple micro tunnels.
For how long have I used the solution?
We just completed a POC. I just started with the company.
What do I think about the stability of the solution?
The stability is good. The solution is reliable. We've had no issues with stability. I'd rate the stability eight out of ten.
What do I think about the scalability of the solution?
We have almost 300 users.
I'd rate the scalability six out of ten. The policy creation is difficult. It's complicated to add them, and therefore scaling may take a while.
How are customer service and support?
I don't really deal with technical support. We get support from a third-party vendor, not Zscaler directly.
Which solution did I use previously and why did I switch?
We have used a different solution in the past. Zscaler, we can deploy on VM servers.
How was the initial setup?
We've only completed a POC and plan to roll out a full implementation soon. In the past, I have implemented it completely as well. We are planning to deploy for the sales users first.
It's not a difficult process. Once the agent is installed, it needs to be verified with the console. The deployment takes between 30 to 45 days, depending on the level of support needed to complete the task. The issue is our sales team are work from home users. That can make the process longer.
We also need to create user policies before the full deployment happens. Different policies are needed for different users. We may need to create three to four different policies for different user sets.
What about the implementation team?
We have a third party that we get the solution.
What's my experience with pricing, setup cost, and licensing?
We have yet to receive the cost from Zscaler. We've only done a POC. My understanding is the solution is reasonably priced. I'd rate the pricing eight out of ten.
What other advice do I have?
We are an end-user. We may be a future partner.
It is good for a small environment of 80 to 100 users. I'm not sure if it works for very large organizations. This solution requires less maintenance and makes server access easy - instead of, for example, standalone VPN access.
I'd rate the solution ten out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Microsoft Azure

Is easy to scale and deploy, and has an intuitive user interface
Pros and Cons
- "I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."
- "Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."

The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies.
What needs improvement?
Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers.
For how long have I used the solution?
We've been working with this solution since 2017. Our customers use a cloud deployment of this solution.
What do I think about the stability of the solution?
The stability overall in the developed regions, such as the US and Europe, is fairly good. In certain regions, such as South Africa, Zscaler has not been stable for some time.
What do I think about the scalability of the solution?
It is easy to scale. Additional sites and licenses can be added quickly and easily.
How are customer service and support?
Zscaler's technical support is not too bad. They have been helpful when I have had issues, but I have not had to contact them much.
How was the initial setup?
The initial deployment process is quite easy. I've implemented Zscaler Internet Access in large, multinational corporations and recently at a company that is in 64 countries in the world. The deployment is always fairly quick. I have also worked with smaller clients, and Zscaler deployment is even easier in these cases.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
My advice would be to ensure that you have a good implementer and reseller who can provide guidance. The reseller should be aligned with those who work in security and needs to be aware of anything that might need an exception that needs to be created. This will help avoid any surprises when the solution is live. The other important aspect to consider is training.
Overall, I would rate Zscaler at eight on a scale from one to ten.

- "The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
What is our primary use case?
It's a proxy solution, and we use it for reverse proxy, DNS security, and storage security.
What is most valuable?

I would give technical support an eight out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We previously used Westcon-Comstor, which was on-premises, but with Zscaler, we moved to the cloud solution.
How was the initial setup?
The initial setup was pretty easy. The deployment took about three months.
What about the implementation team?
Our team of two members along with Zscaler's team implemented the solution.
What was our ROI?
We have seen an ROI. This is a well published product, and you get value for your money.
What's my experience with pricing, setup cost, and licensing?
Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features.
What other advice do I have?
Each use case is different, and you have to evaluate it and take the risk.
On a scale from one to ten, I would rate Zscaler Internet Access at nine.

Controls doesn't affect speed and runs in the background with SSO feature
Pros and Cons
- "Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
- "The solution's pricing is on the higher side. It would be better if it could be lower."
What is our primary use case?
We use the tool to manage all end-user traffic. It's mainly for web filtering on every device, not for backend server traffic.
What is most valuable?
Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far.

The solution's pricing is on the higher side. It would be better if it could be lower.
For how long have I used the solution?
I have been using the product for a year.
What do I think about the stability of the solution?
The product is quite stable. There were some challenges with speed and performance when connected to a different region, but once they fixed the policy and routed through our region, everything worked fine.
What do I think about the scalability of the solution?
The tool should be scalable - we have many employees, and it's covering well. I can't comment on limitations for other companies with thousands of computers.
How was the initial setup?
We pushed it through policy to all computers, so we didn't need people to do it manually. You need someone overseeing it but not heavily involved or specifically dedicated. It can be handled with other workloads.
What was our ROI?
The main reason for getting the solution was for better security, not for time or management savings. It didn't decrease effort for our security team, but it improved our overall security posture.
What other advice do I have?
I like Zscaler Internet Access. We've been using it for a while, and it's working very well. However, we're still in the early stages of identifying the full solution and requirements.
I rate it a ten out of ten.
