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 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."
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?

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?

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."

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.
