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.

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?

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.
What needs improvement?
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.

Though the solution offers good support and stability, it needs to improve its interface
Pros and Cons
- "Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
- "Currently, the solution's interface is not that user-friendly."
What is most valuable?
The permission settings in the solutions are the most valuable feature in the solution since it allows me to assign roles and permissions.
What needs improvement?
I am just an end-user of the solution. I can't speak on what needs improvement from an admin's perspective. The interface of the solution needs to be clear and user-friendly. Currently, the solution's interface is not that user-friendly.
Zscaler is not like Okta. Okta has a marketplace, while Zscaler doesn't have one. Zscaler needs to have a marketplace.
For how long have I used the solution?
I have been using Zscaler Internet Access for two years. I am using the solution's latest version. My company is just a customer of the solution.
What do I think about the stability of the solution?
Stability-wise, I rate the solution a nine and a half out of ten.
What do I think about the scalability of the solution?
Scalability-wise, I rate the solution an eight out of ten.
My company has 200 users using the solution.
How are customer service and support?
I rate the solution's technical support more than nine out of ten.
How would you rate customer service and support?
Positive
How was the initial setup?
I rate the setup phase a nine on a scale of one to ten, where one is difficult and ten is easy. The setup phase was easy.
The cloud is deployed on-premises.
The time taken for deployment is around fifteen minutes.
One admin person is required for deployment.
What's my experience with pricing, setup cost, and licensing?
I am not aware of the solution's pricing model since my company paid for the solution.
What other advice do I have?
I like Zscaler Internet Access a lot.
There are some sites it fails to find and block, causing such sites to get away from Zscaler Internet Access.
Overall, I rate the solution a seven out of ten.
Which deployment model are you using for this solution?
On-premises

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."
What is most valuable?
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.
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.

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

Easy to use, straightforward to set up, and very reliable
Pros and Cons
- "The initial setup is very straightforward."
- "If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
What is our primary use case?
Basically, they usually are the endpoint VPN connection to secure the end-user device. They also integrate with the SD One solution to form a secure endpoint assessment for the SD One, with security from the endpoints to the network.
It serves as protection for the endpoint, especially laptops, to secure any internet access. Even when you assess the wireless itself, they also make sure that the traffic from the laptop is encrypted.
What is most valuable?
The way they do it is very easy to use at the moment. If you power on the laptop, they will survey. It's very easy for the user. The user doesn't really need to do anything except make sure that the access is there. That's all.
The initial setup is very straightforward.
It is easy to scale.
The solution is stable.
What needs improvement?
If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal.
For how long have I used the solution?
I've used the solution for 18 months.
What do I think about the stability of the solution?
The solution is very stable and reliable. There are no bugs or glitches. It doesn't crash or freeze.
What do I think about the scalability of the solution?
The solution can scale very well.
How are customer service and support?
Very minimal technical support has been required since the solution is so stable and easy to use.
How was the initial setup?
The implementation process is easy. The agent they use runs very smoothly.
What's my experience with pricing, setup cost, and licensing?
They do have a minimum number of users required to make it viable. You need to have 500 users. Based on the licensing scheme, they offer 500 users. The initial level would be $3/month per user.
What other advice do I have?
I'd rate the solution eight out of ten. It is very easy to use.
