Complete and well-organized with good proxy capabilities
Pros and Cons
- "We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
- "Sometimes it's not easy to use during large deployments of workstations."
What is our primary use case?
We primarily use the product for proxy services. We are using that to manage services with a third party, so we are not directly exposed to Zscaler.

We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution. We also like the capability to have local agents on PCs.
We are using that in managed services, so we are happy with the managed service as it is.
It's a very complete solution and well-organized.
What needs improvement?
Sometimes it's not easy to use during large deployments of workstations. It's a bottleneck from a network point of view.
It's a technical solution, so you need to have good architects knowledgeable on Zscaler.
We don't need any other added features.

I've been using the product for nearly two years.
What do I think about the scalability of the solution?
We have around 1,000 users on the solution.

It's a managed service, so it's included in the service.
What other advice do I have?
We don't have a direct relationship with Zscaler as we use it in a managed service.
I'd advise new users to be sure that they have good architects to integrate. It's quite complicated.
Sometimes the complexity of integrating with legacy and other complex setups is a chore.

The scalability is perfect, the setup is straightforward, and the ROI is excellent
Pros and Cons
- "The solution replaces multiple vendor technologies with one which makes it worth the cost."
- "The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
What is our primary use case?
The solution is used to manage and protect end users' access to internet resources, websites, and web applications while checking for malicious or bad content in order to grant or block access to certain sites.
What is most valuable?
This solution has a lot of valuable features. The most valuable features of the solution are URL filtering, CASB, data leak prevention, DLP, and also ZDX a digital experience monitoring option.
What needs improvement?
The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security.
For how long have I used the solution?
I have been using the solution for two years.
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 would you rate customer service and support?
Positive
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?

Global Head of Information and Cloud Security Architecture
Great user experience, issue-free, and has good web filtering
Pros and Cons
- "It is easy to set up the solution."
- "In terms of user experience, it could be better."
What is our primary use case?
We are using the solution for internet security. It's mostly web-based filtering.
We are into this modern world, meaning, we are working from home in hybrid scenario. Due to the pandemic, we have seen a lot of shifts towards a hybrid model of work. That provides lots of challenges in terms of security including, how to protect the users' machines and other devices. That is one of the core use cases. Wherever you are, you need to be protected. However, the traditional approaches such as a legacy-based proxy system won't work.
If we have some kind of critical systems, we need to figure out how we can provide the access to all these users, all these remote or roaming users, access to these critical areas, and we need to eliminate those legacy-based VPNs. Zscaler is doing it best. Zscaler offers the best service since you are protected wherever you are.
What is most valuable?
The internet access is great. It offers good web filtering. It has DLP features. We can monitor our networks with ease. We can monitor the usage, bandwidth, chop, chalking, all these things we can monitor. On top of that, it is providing advanced threat protection ATP, which means any kind of malicious network or malicious payloads that are going through our network can be detected and it can be blocked. We can have a certain kind of block list. There are multiple levels of features.
We have fewer issues with Zscaler.
In terms of user experience, that is also excellent.
In terms of reporting to senior management, it gives us a clear picture of what needs to be achieved about that solution.
It is easy to set up the solution.
The solution is stable.
It is a scalable product.
What needs improvement?
In terms of user experience, it could be better. It all depends upon the configuration, though. At the moment, they are one of the best. In terms of room of improvement, it depends upon the specific use cases of the customers.
For example, it might be that some of the users are having some kind of connectivity issue. It depends upon how those users are connected. It may not be a product issue. Or maybe they are using a VPN. Local banks won't allow connectivity to their application over a VPN or over a cloud-based proxy service, for example. In some countries, the local banks restrict these kinds of communications. There needs to be some whitelisting done to get those users connected.
For how long have I used the solution?
At the moment, we are trying to onboard that solution. In my previous organization, I have used that solution. In my current organization, we are trying to onboard the solution.
What do I think about the stability of the solution?
It is a stable solution. I never faced any kind of downtime for my critical services. They have a higher availability. If one of the locations goes down, automatically, it'll scale to a preferred location.
What do I think about the scalability of the solution?
The solution scales very well.
In the last three or four years, there has been a shift towards this product. We likely will increase usage.
How are customer service and support?
I've never directly dealt with technical support. My team handles any issues and would deal with them directly.
How was the initial setup?
It is easy to set up. However, you need manpower and you need a team to deliver these kinds of things. It's not a plug-and-play thing. It has lots of configurations. We need to deploy the agents. We need to set up those configurations. If we have multiple offices, we need to understand the routing and what mechanisms are in place. That's why it takes a team.
The length of deployment depends on the company and environment. You're looking at the number of networks, the number of servers.
What's my experience with pricing, setup cost, and licensing?
I can't speak to the costs. I don't handle the licensing.
What other advice do I have?
I'm a customer and end-user.
I'm not sure of the exact version of the solution.
Zscaler is a cloud service provider, so they are hosting their services on their own cloud. They might be using the public cloud. I'm not sure. However, it's not an on-premise solution. It's a cloud-based proxy.
You need to perform that due diligence. You need to understand your use cases, including the number of users and how many are working from home or roaming, et cetera. You need to understand hosting, and how to protect servers. There's a lot of understanding you need to have before you can begin implementing anything.
I'd rate the solution eight out of ten.

The initial setup was straightforward - Zscaler Internet Access is plug-and-play, and it's the simplest proxy solution I could recommend.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?

What other advice do I have?
We use other similar products and find them to be a bit more preferable to Zscaler. I would rate this solution an eight out of ten.

What needs improvement?
What could be improved in Zscaler Internet Access is its price. It could be cheaper.
For how long have I used the solution?
I'm working for TCS, which is a service management company, so we manage services for our clients. From my perspective, I've been working with Zscaler Internet Access for six months, but the client could be using it longer than that period. In my case, I've been working with this particular client on Zscaler Internet Access for six months. My company TCS is a partner of Zscaler.
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.

Good VPN technology and scales with our requirements
Pros and Cons
- "The VPN is valuable, as the whole technology is very different from a traditional VPN."
- "There are a few features that are not compatible with the Azure cloud."
What is our primary use case?
We use Zscaler for VPN connections and for internet security.
What is most valuable?
The internet security that it provides is valuable.
The VPN is valuable, as the whole technology is very different from a traditional VPN.
What needs improvement?
There are a few features that are not compatible with the Azure cloud.
It's not fully compatible with our environment because of the way that it is divided into business units. In order to get it working properly, there are some things that we had to put in for enhancements. Otherwise, everything works well.
For how long have I used the solution?
We have been using Zscaler Internet Access for about a year.
What do I think about the stability of the solution?
It is a stable solution, although once or twice, we had issues with latency and slowness. Other than on these occasions, it has been fine.
What do I think about the scalability of the solution?
Scalability-wise, everything is good. We have approximately 3,000 users and we do plan to increase usage. Ultimately, we want to include everyone, which is about 10,000 users.

How was the initial setup?
The initial setup is straightforward and the deployment took place over a couple of days.
