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.

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?

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.

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.

Provides another layer of protection when a user goes to the Internet to browse or download something
Pros and Cons
  • "Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."
  • "They could provide more time for the onboarding the training of an IT person."

What is our primary use case?

We have Windows 10 laptops. We wanted help securing our laptops for remote work, but we don't have the server for this infrastructure. Whereas, with this solution, the cloud server is managed by Zscaler. 

It is a pretty lean solution. We only need to manage the agent and some very small tools on the laptops.

How has it helped my organization?

Currently, we have an on-premise firewall. However, most of the time, users are not working in the office. Therefore, we need to use something, like a Secure Access Service Edge (SASE), to help users. So, we are trying to protect users without a corporate firewall.

We just wanted laptops to have more secure features to help users and protect the company's data. There are two major things deployed on our laptops: Zscaler Internet Access and endpoint detection response (EDR).

Zscaler Internet Access has helped enable our digital transformation.

What is most valuable?

When you try to access suspicious websites, they will give you a warning. This helps us with user access without our office network.

Its cyberthreat protection is important for our needs. We use it for Internet access control, e.g., accessing web pages. We also use it when a user downloads or uploads files from the Internet.

When a user goes to the Internet to browse or download something, it is secured by this tool. This is important to us because it is another layer of protection.

What needs improvement?

They could provide more time for the onboarding the training of an IT person.

We did run into some compatibility issues. We just needed to test its configurations on the web portal and that detected the issues.

For how long have I used the solution?

I have been using it for half a year.

What do I think about the stability of the solution?

We haven't had any issues with stability.

No maintenance is required.

What do I think about the scalability of the solution?

We have 120 users. We have never tested it to go above 1,000 users. It shouldn't have problems because it is an agent working on the laptops using a centralized online server. 

How are customer service and support?

The technical support is very good. We create a ticket every week or two.

How would you rate customer service and support?

Positive

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

We didn't have an Internet access control solution previously, only anti-malware for endpoint protection.

Our legacy systems only protected our on-premise network.

How was the initial setup?

The initial setup was straightforward. It took about three days to set up.

What was our ROI?

Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team.

Versus deploying and managing traditional network security hardware, the solution has saved us about four hours a week.

The solution has helped us reduce the number of infected devices in our organization by proactively preventing attacks because some users were unaware of some malware sites.

Which other solutions did I evaluate?

We evaluated two or three different vendors, but finally selected Zscaler Internet Access due to its reputation. Also, the GUI for Zscaler Internet Access was very clear when we tested it.

What other advice do I have?

We are not using the solution for data loss prevention.

When you select this product, test it with other tools running on your machine to ensure there are no compatibility issues between different products.

I would rate it as nine out of 10.

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.

Its most valuable feature is the well-structured functioning of services and helping us monitor them in the best possible way
Pros and Cons
  • "The solution’s customer service is good."
  • "They should enhance the audit reporting feature."

What is our primary use case?

We use the solution for web security services such as DLP, VPN, BPA, ZIA, and CASB.

 

How has it helped my organization?

We needed a solution to control the user traffic on the internet earlier. But now, with Zscaler's help, we can adequately handle the data using CASB. Also, we can control URLs and Web accesses with the help of its web security gateway feature. Along with this, we are controlling the data leak assessment on the internet with DLP's help.

What is most valuable?

The solution's most valuable feature is the well-structured functioning of services. It allows us to monitor things in the best possible way. It has all the features separated well from each other. For instance, they have a separate portal in case one wants to control anything on the internet. The other valuable feature is its ability to audit the reports well.

What needs improvement?

They recently improved a few things with the new version. They should enhance the audit reporting feature. They are providing a very basic DLP solution, but it needs improvement. If they improve the DLP solution, it will be a better solution in the future. They should work on the bandwidth of the CASB solution as well. 

For how long have I used the solution?

We started the solution's POC in October but it is not yet fully deployed.

How are customer service and support?

The solution’s customer service is good.

How would you rate customer service and support?

Positive

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

I have done the POC for Cisco Umbrella and Netskope before. Netskope is a user-friendly solution. But Zscaler is better than other solutions regarding its monitoring services.

How was the initial setup?

The solution’s setup is pretty straightforward, but it depends on your experience with Zscaler. It would get a bit difficult for a new buyer owing to multiple profile setups and configurations during the process. I rate the solution’s initial setup as a nine.

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

I rate the solution's pricing as seven. It is costlier than other solutions. They have multiple standard licenses, but there is no additional cost included.

What other advice do I have?

If you want to establish the right controls from a web security perspective, it's one of the best products in the market. Again, opting for the solution depends on the particular requirement. If you are looking for a solution for banking services, then, you should go with Symantec Blue Coat for a better DLP solution. But if you need a mix of VPN, CASB, and Web Security Gateway, then Zscaler is the better solution.

I rate the solution as an eight out of ten.

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.

Is stable, easy to scale and set up, and helps to put central security controls on roaming users
Pros and Cons
  • "The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
  • "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?

The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users.

What needs improvement?

The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again.

For how long have I used the solution?

I've been using this solution for one and a half years.

It's on Zscaler cloud.

What do I think about the stability of the solution?

I find Zscaler to be very stable.

What do I think about the scalability of the solution?

It's very scalable because it's the cloud version. We have 100,000 users across all levels.

How are customer service and support?

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.
