Multifeatured solution that stops DDoS attacks, filters URLs, and restricts users
Pros and Cons
  • "The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
  • "What could be improved in Zscaler Internet Access is its price. It could be cheaper."

What is our primary use case?

Zscaler Internet Access is used for internet access, security related to internet access, and in some cases, connecting to online applications.

What is most valuable?

The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN.

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.

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.

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.

What is most valuable?

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.

For how long have I used the solution?

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. 

We do not have plans to increase usage. 

Which solution did I use previously and why did I switch?

We have other products as well. In the current set of products, I'm not forcing any swaps or changes.

How was the initial setup?

It's a managed service. We are not exposed to the initial setup process.

What's my experience with pricing, setup cost, and licensing?

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.

I'd rate the solution eight out of ten.

Excellent granular policy controls
Pros and Cons
  • "Zscaler Internet Access's best feature is the granular policy controls."
  • "Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."

What is most valuable?

Zscaler Internet Access's best feature is the granular policy controls.

What needs improvement?

Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative.

For how long have I used the solution?

I've been using Zscaler Internet Access for over five years.

What do I think about the stability of the solution?

Zscaler Internet Access's stability is pretty good, and when an issue occurs, they're very quick to notify the end-users and fix it.

What do I think about the scalability of the solution?

Zscaler Internet Access is very scalable, and requests for scalable solutions are met quickly.

How are customer service and support?

Zscaler Internet Access's technical support is very good and fast. Sometimes, I've had trouble with level one people, but once an issue is escalated to higher-up engineers, they're pretty quick to provide the solutions.

How was the initial setup?

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?

Zscaler Internet Access is very good, and I would recommend it to others. I would give it a rating of eight out of ten.

Highly scalable with good technical support
Pros and Cons
  • "Overall, we're very happy with our product."
  • "The price of the solution could be improved."

What is our primary use case?

Our client is a government client with many different work groups. 

What is most valuable?

Overall, we're very happy with our product.

What needs improvement?

The price of the solution could be improved. 

For how long have I used the solution?

We have been using the solution for two years, since the start of COVID. 

What do I think about the stability of the solution?

We have had no concerns with the solution's stability so far.

What do I think about the scalability of the solution?

The solution is scalable, we have around 70,000 total users across various environments.

How are customer service and support?

They've been very good, though as we are still assessing the solution you would expect them to be very good.

Which solution did I use previously and why did I switch?

We also use Cisco Umbrella and we tend to use that more. 

How was the initial setup?

The initial setup wasn't easy in our case, as we have thousands of users spread across different environments. Due to our extensive requirements, initial setup is never going to be easy.

What's my experience with pricing, setup cost, and licensing?

We have found the solution to be expensive. 

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.

Which deployment model are you using for this solution?

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 are customer service and technical support?

We have been in contact with technical support and they are very responsive. They also have TAM support, which means that we have a dedicated engineer to look into our issues. That is nice to have.

Which solution did I use previously and why did I switch?

I have used Cisco Umbrella in the past, which is similar. However, there are definitely differences between these two solutions. Cisco Umbrella is a DNS-based web filtering solution, whereas Zscaler is a cloud-based web application firewall combined with a regular firewall, antivirus, IPS, and other security features.

How was the initial setup?

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

What about the implementation team?

We used Zscaler Professional Services for the deployment.

What other advice do I have?

In summary, this is a good product and I completely recommend it.

I would rate this solution a nine out of ten.

A stable solution with good security but needs to do more to address phishing emails
Pros and Cons
  • "The security is excellent."
  • "I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again."

What is our primary use case?

The product is an endpoint solution for private and internet security. I use it myself in my home office. I'm in sales. I use it as an endpoint solution for my laptop, for my device, in order to get access to some internal service applications, such as pricing and time management tools.

What is most valuable?

Zscaler is a very stable solution.

The security is excellent.

What needs improvement?

I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again.

From time to time, there's instability in terms of the user experience. I don't know whether it's Zscaler or the time instrument server itself. I don't know the root cause here, that this is the only thing, that causes me issues. Otherwise, I'm quite happy with it.

The solution should do more in regards to handling phishing emails. They maybe should pair with a solution like Palo Alto in order to offer a more holistic view of the security and offer behavioral analytics or endpoint protection, etc., and all from one vendor. Data Lake, for example, is a product that gets the information and gives feedback to the user. There seems to be a high volume of phishing emails that we get, and I'd like to understand what the company is doing to address that. Zscaler seems like it's just a bit too static.

For how long have I used the solution?

I've been using the solution for four years.

What do I think about the stability of the solution?

Aside from issues I've had accessing time management from time to time, it seems to be a stable solution.

What do I think about the scalability of the solution?

The question of scalability would be best posed to our CSO. However, my whole team uses it. It's been scaled in our organization to a very small extent. In that sense, it was easy to scale. 

I don't know the maximum capacity, however, it's my understanding that the solution is suitable for organizations like us with about 3,000 employees.

How are customer service and technical support?

We have our own technical support. I've never directly contacted Zscaler in order to get assistance.

I purely go to our first level of support. Any issues I've ever had have been solved on the first or second level. It's my understanding, that if the issue exceeds a certain level of support, it would be forwarded to Zscaler. However, I've never had issues of that nature. The only issues I've dealt with have been rather easy to solve.

Which solution did I use previously and why did I switch?

We were previously using Pulse Secure in our organization. I needed to switch it on and off. On top of that, certain applications I could not reach. This was slow and proved to be unstable.

Zscaler, on the other hand, is more stable and also more secure.

How was the initial setup?

The initial setup was straightforward. It wasn't complex at all.

My understanding was that the deployment itself happened pretty quickly.

There was an announcement from our security, and by our CSO. Then it was rolled out and Pulse Secure was turned off. There was a migration phase in the project and that's it. It all happened rather fast.

What's my experience with pricing, setup cost, and licensing?

I don't handle billing or payments and therefore don't know the exact pricing of the solution of what exactly our organization pays.

Which other solutions did I evaluate?

I wasn't involved in the decision-making process when it came to looking for a solution.

What other advice do I have?

We're just a customer.

I would recommend other users also have a glance at other solutions. Options like Prisma Access by Palo Alto or Check Point may be ideal, depending on the needs of the business.

Zscaler seems easy to understand and easy to use, however, there is probably some room for improvements. At my former company, we were using Check Point. This was also pretty good. Zscaler seems more modern, however, I'm referencing an experience from some 10 years ago.

Overall, I would rate the solution seven out of ten.
