AI decision-making on quarantined documents reduces manual work
Pros and Cons
  • "For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
  • "The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."

What is our primary use case?

It's primarily for end-user access to the public internet. We use the proxy functionality and the URL Filtering.

We have a global policy for all our users. While there are a few categories of URLs that we are not allowed to do SSL inspection on, the primary function for us is to do SSL inspection so that we can make use of the built-in anti-malware and antivirus—the advanced-threat features—within the platform. We do SSL inspection of some 80 percent of all the traffic and we can evaluate if it's malicious or not.

It is a cloud solution where pretty much everything is handled by Zscaler.

How has it helped my organization?

Zscaler has helped to reduce the time we spend managing security policies. That is very important to us. A lot of the features it has are AI-based decision-making. For instance, if we implement a sandboxing rule for how files of a certain type should be inspected, we also can activate the AI decision-making process. That way, even if a file is new to the sandboxing environment, it can still see that it is a PDF and has these and these characteristics. Based on that, the AI says that "No, this file is not malicious," even though it normally would have been quarantined and sandboxed and have gone through the whole analysis process. The AI helps out in minimizing the time to do that analysis. And that also helps in reducing the burden of someone actually having to do things manually.

If you count everything that was involved in managing the appliances, the lifecycle management, and support contracts, in our old environment, we have reduced the number of FTEs managing the environment from five or six to about two.

It has also definitely helped reduce the number of infected devices in our organization by proactively preventing attacks. Since we scan almost all of the traffic, we now see how much of the traffic is "malicious." In our environment, we block about 1.6 million threats every quarter, but we don't know the severity of those threats. Maybe 1 million of them are malicious content in some way, while half a million are adware. But there are real threats that are being blocked, like botnet callbacks, cross-site scripting, and browser exploits. On average, we are blocking about 500,000 threats per month. 

What is most valuable?

There are a bunch of different capabilities that are valuable within the platform. We use quite a lot of them, but not everything. The ones that are most important to us are the URL Filtering and the application control. 

For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway. But there are parts of it that we don't use yet, like the DLP functions. Instead, we are using the Zscaler Cloud Sandbox feature for content that is downloaded as files. We detonate the document in a sandbox and see if it's malicious or not.

It's a very easy-to-learn and easy-to-use platform, even for me as a more non-technical person. I'm still able to do a lot of work in this platform.

What needs improvement?

The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments. It's quite hard to get a good report. 

Another issue is that the API documentation could be a bit more up-to-date. They're implementing stuff, but not updating the documentation all the time.

Zscaler Internet Access
August 2025
Learn what your peers think about Zscaler Internet Access. Get advice and tips from experienced pros sharing their opinions. Updated: August 2025.
866,561 professionals have used our research since 2012.

For how long have I used the solution?

We have been using Zscaler Internet Access for the last five years.

What do I think about the stability of the solution?

Since we have global reach, we are seeing a bit more instability in Asia, primarily in China, but I'm not sure that it's related to Zscaler. I think it's more due to how China does things in terms of internet access.

What do I think about the scalability of the solution?

It scales very well, if you go for the cloud-based solution alone. In certain regions in the world, we have started to implement local appliances, like a VEN node, where we don't have good coverage from Zscaler's public data centers. But if you only use the public data centers, it's getting a lot better. A while back, there were 35 or 40 data centers that we could use globally, but now there are over 80. So the scalability is quite good for us.

How are customer service and support?

Zscaler's technical support team is good at what they do, and they help us fix our problems quite fast. I would rate them eight on a scale of one to 10. There's always room for improvement.

We have had issues from time to time where they don't really see our problem as a problem, but we, as a customer, are being affected. They have a few different ISPs that take care of traffic to and from their data centers, and when their ISP is not performing, we, as customers, are suffering. There have been occasions when we have seen that our traffic is being routed very strangely within the Zscaler network, but they don't see that as a problem. We do, because all of a sudden, all of our Swedish users are going to the data center in Norway instead of Sweden. For Zscaler that is not a problem because they are still doing their job. But for our users, it's complicated because Norway is not part of the European Union, whereas Sweden is. If they go through the VEN node in Oslo, Norway, we cannot reach stuff that is EU-regulated, such as export and import functions within the EU. That is a big part of what we do. At times, it has been hard to get the Zscaler TAC team to understand that this is a problem for us, as a company.

How would you rate customer service and support?

Positive

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

We used to have an on-prem solution doing pretty much the same thing as Zscaler, but as our strategy is cloud-first and internet-first, we thought that we should also use a cloud-based solution. We started to look at the alternatives, five or six years ago. What we saw was that there was only one, at the time, that was mature enough for our needs.

Since then, Zscaler has evolved quite a lot. In the beginning, there was no Zscaler Client Connector, an agent on your computer. It was all cloud-based, but that changed about a half a year after we started to use Zscaler. We assessed whether Zscaler fit our needs or not and we saw that for 75 or 80 percent of our needs, it was a good fit. Some aspects were not mature back then but they have matured over time.

How was the initial setup?

The initial deployment was quite straightforward. I wasn't really on board at the time the implementation of Zscaler took place, but overall, when new features and functionalities are added to the product, it's quite straightforward to implement them and to roll them out to large user groups, or globally. From a rollout perspective, it's quite easy to use.

Initially, one of our demands was that everything should be cloud-based, meaning we shouldn't have any agents on each computer. We learned the hard way that such an approach doesn't work well, because you need something to control the path from the user's computer to the Zscaler cloud. You need to be able to steer how the traffic goes. You can do that with PAC files. But ultimately, together with Zscaler, we figured out that a client was needed, at least for our needs.

What was our ROI?

Zscaler has helped us save costs by enabling us to decommission all of our legacy proxies. We had at least nine locations with appliances, and we had multiple appliances per location. It has helped us save money.

We have also seen ROI in terms of the cost of both the lifecycle management and the service and support contract that we previously needed. We have saved quite a lot there. I don't know the exact numbers, because I'm not in charge of the finances, but if you count the resources needed to manage the platform, we have saved up to 45 or 50 percent of the cost we used to have.

Which other solutions did I evaluate?

Back then, there weren't many other cloud-based solutions available. There were hybrid models, but we wanted a completely cloud-based solution. 

At the time, Symantec had the beginning of a cloud-based solution, but it was very immature and it didn't work as well as Zscaler. Zscaler had been around since around 2010 and was five years into their journey, while Symantec was only a year or two into their journey. We opted for the most mature at that time.

Since then, we have looked at other solutions, including Netskope and a few others. They are similar in their design, but Zscaler has features in its design that make it stand out from the competitors. For instance, their scanning methodology is something like, "Scan once, analyze many times." That means there is a one-time scan of the traffic, but with multiple different threat engines, for antivirus and anti-malware, et cetera. And they do it only in the RAM memory of their cloud solution machines, which makes it super-fast. They can scan a lot of traffic in a very short amount of time. That part is something that a lot of other vendors are not doing. They're scanning in sequence, not in parallel.

What other advice do I have?

Make use of the Zscaler Client Connector as much as you can, with all of the functionality that comes with it. Also, do not allow the users to disable the Zscaler Client Connector, because then you don't know if traffic is actually going through Zscaler or not. If it's always on, you know that if something is not working, it's your policies that are doing something to the traffic. We used to make it possible for a user to disable the Zscaler Client Connector, which then made it impossible for us, as the team that troubleshoots problems, to know if the traffic was actually going through Zscaler or not. If you don't have that control, you don't know where the problem is. Now, at least we know that it's either on the client or it's on Zscaler or it's on the destination that they're trying to reach.

As for saving time with this system versus deploying and managing traditional network security hardware, it depends on how you build your management of the solution. We have opted for a solution where we manage everything centrally. We have one IT team that manages all of the Zscaler Internet Access policies and settings. But there is an option, and it's one of the strengths of Zscaler, to delegate control of parts or all of the solution to other teams. For instance, you could have URL Filtering policies that are managed by a local IT team in a given country. We don't do that. We manage everything from one team and we control everything, for our whole organization, from this management platform. We control the forwarding policies, the application access policies, the URL Filtering policies—pretty much everything.

Configuring policies is user-friendly but challenges with stability
Pros and Cons
  • "The policies are very intuitive and easy to configure, with very little possibility of messing things up."
  • "One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."

What is our primary use case?

Primarily, it was to replace our existing on-premises box infrastructure. That's what it started with. And lately, we've been using it more for secure web gateway purposes.

How has it helped my organization?

It's primarily meant for perimeter security and the ability to securely access the internet and SaaS applications. So that has definitely helped us get rid of our bulky firewall hardware firewalls, at least for internet access. So that's a cost optimization. And performance. It definitely helps us boost performance.

What is most valuable?

The ease of deployment is the most valuable feature. All it takes is building a few QRE or ITC tunnels and installing agents. It's a piece of cake. 

And the policies are very intuitive and easy to configure, with very little possibility of messing things up. I also like the great analytics and good visibility into the traffic that goes out of my organization. 

Shadow ID Discovery is also great for finding out what SaaS applications people in my organization are trying to access.

What needs improvement?

One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China.

This concern is a common one for vendors across the board when dealing with the Chinese market. So, currently, there is the Great Firewall of China. This firewall can significantly impact internet performance for users in China. A better presence in China from Zscaler could mean more breakout points between China and the rest of the world. 

This would help to improve internet performance for users in China and make Zscaler a more viable solution for organizations with a presence in China.

For how long have I used the solution?

I started using it in 2015, but then I used it intermittently for the next couple of years. But lately, I've been using it quite a lot. So I've been working with it for about seven years now.

What do I think about the stability of the solution?

Occasionally, I've faced challenges with applications going down, but these incidents don't usually result in disconnections. 

If I were to rate its stability on a scale of one to ten, with ten being the most stable, I would place it around a seven, I suppose.

What do I think about the scalability of the solution?

I've never encountered challenges where a client exceeded the bandwidth or processing limits of Zscaler. When you reach your peak, the solution is flexible enough to handle it. 

If necessary, you can provision another circuit to increase your Internet bandwidth and set up an additional enforcement point, which is essentially a Zscaler reinforcement point. So, it's highly elastic and scalable.

I would give scalability a perfect ten out of ten rating.

How are customer service and support?

The customer service and support are fairly good. 

In terms of their technical capabilities, response times, and issue resolution, we've had positive interactions with their support.

How would you rate customer service and support?

Positive

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

The primary alternative for Zscaler is Prisma Access. It stands out as the strongest contender. Additionally, there's NetScope in the mix, although it's not a direct comparison. Another player is Blue Coat, or rather Symantec, now Broadcom. They also compete in this space. However, from what I've observed, most clients transitioning from traditional proxy setups tend to gravitate towards either Zscaler or Prisma.

Prisma Access extends beyond mere web security. This puts it in a separate category, making a direct comparison with Zscaler Internet Access somewhat challenging. Prisma offers a broader array of features, including threat profiling, threat intelligence, diverse integrations, endpoint security evaluations, and deep packet inspection. These are areas where Zscaler Internet Access falls short. Zscaler, essentially a cloud proxy, serves a specific purpose. 

On the other hand, Palo Alto Networks not only operates as a proxy but also incorporates firewall functionality. It functions as a service, includes VPN replacement capabilities, and encompasses features like antivirus, anti-spyware, and IPS for threat filtering. Palo Alto holds an advantage in these aspects. However, if your primary aim is to replace an on-premises proxy, Zscaler is the way to go. Opting for Prisma Access exclusively for proxy functionalities might prove cost-prohibitive.

How was the initial setup?

I would rate my experience with the initial setup an eight out of ten, where one being difficult and ten being easy to setup.

With regard to complexity, it largely depends on the number of redundancies that you require. For example, if you just have a standby setup with maybe two or three Zscaler enforcement nodes that your tunnels need to terminate on, it's fairly simple. 

However, the more redundancy and higher availability requirements that the company has, the more complex it gets. So it can get pretty complicated if you have some crazy requirements with regard to high availability and redundancy.

You just need one person to deploy the solution. One person can mostly do it. A lot of parts as well. 

You would require an endpoint specialist; someone who manages the endpoints. Additionally, you might need someone from your SOC to ensure that you're able to ingest all the logs and security alerts that are being dumped into the same solution. Perhaps one or two individuals for testing purposes. The policy installation process is quite straightforward and shouldn't take a lot of time. One person should be sufficient for that.

What about the implementation team?

We deployed the solution ourselves. We have a team of in-house experts who can troubleshoot any issues that may arise. We have also used Zscaler's professional services team on occasion, for example, to help us with sizing and design, or when there are complex requirements from our clients. But for the most part, we're able to handle the ZIA deployment ourselves.

Most standard deployments take around two weeks. For example, I deployed Zscaler Internet Access (ZIA) for my previous organization, with 20,000 users in two weeks. However, I've also seen deployments for 50,000 to 60,000 users that took at least three to four months. 

The exact deployment time will vary depending on the size of the deployment, the complexity of the environment, and the specific requirements of the organization.

In a typical deployment process, the first step is to procure licenses. You can either do this yourself, or Zscaler can do it for you. Once the licenses are procured, Zscaler will create a tenant for your organization. This tenant will include the enforcement nodes that will be used to process traffic for your users.

Following this, the installation of Zscaler tunnels transpires, along with the deployment of the Zscaler Client Connector (ZCC) on user machines. Configuration of policies is then carried out, encompassing aspects such as policy definitions and potential additional inspection of HTTPS traffic. 

Moreover, ancillary facets are incorporated. These entail the establishment of compatible streaming services and TLS inspection. Integration with the corporate identity provider (IdP) is also a crucial step. 

Furthermore, if automation is a consideration, additional automation or orchestration components can be implemented to facilitate automatic policy enforcement. While integration with Extended Detection and Response (XDR) systems is conceivable, this is an aspect I have not personally done. This more or less encapsulates the overall process.

What other advice do I have?

I would suggest knowing the use cases beforehand. Many customers I've seen aren't entirely clear about their specific use cases. They often dive into the product first and then work backward to identify whether Zscaler Internet Access aligns with their needs. Understanding your use cases is essential; it serves as a foundation for determining if Zscaler Internet Access is the right solution. If the required capabilities are already available, or if a few API integrations or lines of code can sustain the existing solution, that's worth considering. This advice isn't exclusive to Zscaler, but I've witnessed clients who become uncertain because they lack the necessary set of use cases that would justify their investment.

Overall, I would rate the solution a seven out of ten for two reasons, namely, the China issue for the improvement section and the pricing is expensive. I am not sure about the exact price, but it is expensive.

Minimal latency and easy to implement
Pros and Cons
  • "One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
  • "There are some performance issues when we add on additional controls."

What is our primary use case?

The main use cases that our clients typically have and why we propose and implement the solution is for a proxy solution. It's designed to create a proxy site-to-site tunnel between the computer trying to access any resources on the Internet or within the offices. Most organizations have a significant number of remote workers - around 30 to 40 percent of their workforce is remote - and they log in from different locations globally, such as Japan, the US, Europe, and Asia. So they need one solution to cover these remote locations and provide a proxy solution.

In addition, we need to have minimum bandwidth latency, and Zscaler is the most suitable product we see. Whenever a customer comes to us with a large geographical spread in terms of their workforce, we propose and implement this solution across the cloud, as required.

What is most valuable?

One feature that is valuable to me from an implementation point of view is that it's very easy to implement. We just had to route in some IPs, and it automatically hops into the nearest Zscaler nodes, which they call it. They have more than 150 nodes across the globe. Essentially, if I'm trying to access a server in India at this point in time, and the server I'm trying to access is somewhere in Singapore or Tokyo, it creates a lot of internet latency. But with Zscaler, it's not the case because they have a server in almost every major hotspot in the world. In India, if you're connecting, they will automatically route to their nearest server. Since they have servers in so many places in the world, we can easily configure them to the nearest server. 

The end-user who's using it doesn't feel the latency, and it's really minimal, less than three milliseconds, six milliseconds, whereas the competition has more than ten milliseconds and eleven milliseconds as latency.

What needs improvement?

There are a couple of areas of improvement in the solution. Firstly, there are some performance issues when we add on additional controls. Zscaler Internet Access is a plain vanilla solution that allows you to add CSV or DLP on top of it. However, once you add these modules, the performance degrades for a bit, and the latency increases significantly. We're talking about a two-fold or three-fold increase in latency. They need to work on this. So the performance goes down when using a lot of features simultaneously.

Moreover, the implementation interface is not very good. It has some minor bugs, and it's not properly streamlined. However, these are not software issues that cannot be resolved. A simple reboot or a call to the reseller personnel can guide you in resolving these issues. But the experience can be more seamless if the interface is improved.

For how long have I used the solution?

I have hands-on experience with Zscaler Internet Access, a cloud proxy solution similar to Cisco's proxy solution.

We've been working with Zscaler Internet Access for almost three years now. We use the basic Zscaler Internet Access with add-ons like CASB and DLP. This is the solution we sell and implement the most.

What do I think about the stability of the solution?

I would rate the stability an eight out of ten. 

What do I think about the scalability of the solution?

It is a scalable solution. I would rate it a ten out of ten. There are more than 15,000 users under different organizations. They are small and medium-sized businesses. The largest organization that deployed Zscaler had 8,000 users. 

How are customer service and support?

The customer service and support team is good. 

How would you rate customer service and support?

Positive

How was the initial setup?

I would rate the initial setup an eight out of ten, where one is difficult and ten is easy. The deployment process is quick, around 6 to 8 weeks. But that depends on the geographical locations we need to cover. If we only need to cover two to three locations, it's good enough.

What about the implementation team?

The deployment process involves building the Zscaler package, which can be vanilla or vanilla plus bundle, and then remotely pushing it to the client machine using Microsoft Intune or whatever it is. Meanwhile, we have to build the configuration and policy based on the client's requirements.

First, what we do is we build the ZScaler package. The package includes the features that will be going through the solution. Once the package is built, it is pushed into the endpoints or machines, such as computers, laptops, and desktops, through Microsoft Intune or SCCM, or any other patching solution that they have. Meanwhile, we configure Zscaler to the nearest hub that the reseller has. They have more than 150 nodes across the globe, so we configure the nearest hub for them. Once that configuration is done, we have established a connection, and the systems have gone online, then you can actually use the solution.

So, it's basically a two-step process. Rolling out the package, rolling out the agent, and configuring the reseller to the nearest hub. That's it. It's a smooth process.

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

Zscaler is transparent about its pricing model. However, it is not a cheap solution. I would rate the licensing model a seven out of ten. 

What other advice do I have?

My advice, generally, is that if a client has a growth prospect with an increasing number of employees moving across the globe, then Zscaler advises having a product that is scalable and fast. By fast, I mean it has low latency, making it very scalable. Zscaler Internet Access is a completely cloud-based product and is highly scalable. It is a reliable solution to have in your IT stack. 

Overall, I would rate Zscaler an eight out of ten. Zscaler Internet Access is highly scalable and has low latency, making it one of the most reliable products with good market support and presence. I rated it an eight and not a ten because there are a couple of constraints in scaling certain things. For example, some customers, such as federal institutions of the US, state of clutter, or some banks, want an on-premise solution. They want more control because Cloud will always have a security issue somewhere or the other, and Zscaler Internet Access does not have an on-prem solution. Also, when you increase the features, it does lag a bit, which should not happen.

Helps with outbound internet connectivity but needs to improve multi-cloud management
Pros and Cons
  • "We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."
  • "Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."

What is our primary use case?

We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering. 

What needs improvement?

Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal. 

For how long have I used the solution?

I have been working with the product for a couple of years. 

What do I think about the stability of the solution?

The product's stability is fine. 

What do I think about the scalability of the solution?

ZIA is not scalable due to the limitation of bandwidth. My company has over 100 users for the product. 

How are customer service and support?

ZIA's support is good. 

How would you rate customer service and support?

Positive

How was the initial setup?

ZIA's setup is not easy because of the multiple clouds. 

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

ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good. 

What other advice do I have?

I would rate the product a seven out of ten. I haven't seen any unique competitive advantage for ZIA over its competitors. ZIA's offerings are offered by competitors as well. However, the product has good security features. However, I wouldn't recommend this product to organizations that require high-security features. I would recommend Palo Alto in those cases. 

Which deployment model are you using for this solution?

Private Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

An excellent solution for web traffic, but the UI cannot be understood easily
Pros and Cons
  • "The most valuable feature of the solution is SWG traffic."
  • "Cloud App’s database should be improved."

What is our primary use case?

Our customer already had the product, which they got from another vendor. They were facing some issues with their existing policies. Our role was to optimize the policy. So we optimized Threat Protection, DLP, and CASB policies per the customer’s requirements. In their environment, G Suite was completely allowed for some users, but they wanted only to allow a specific corporate domain. As per the recommendation, CASB policy must have been in place, but it wasn’t. So we optimized the tool as per their requirement and delivered it.

What is most valuable?

The product has different modules like SWG, CASB, DLP, and Threat Protection. The most valuable feature of the solution is SWG traffic. The product is very good in web traffic.

What needs improvement?

Cloud App’s database should be improved. Currently, they only support and provide granular controls to around 1000 cloud applications. In Netskope, it is more than 3000. Around 65,000 applications are visible to the users in Netskope, but Zscaler only supports around 3000 to 4000. Cloud App is not good. UI is not as easily understandable as Netskope. Netskope has a source, destination, and action policy. In Zscaler, we have to click multiple tabs to get it. It's a bit tricky compared to Netskope. Once we understand it, it's simple.

For how long have I used the solution?

I have been using the solution for four to five months.

What do I think about the stability of the solution?

I rate the solution’s stability an eight out of ten.

What do I think about the scalability of the solution?

I rate the product’s scalability an eight out of ten. Currently, the product is facing major issues in scalability because the company is over ten years old. The data center they have in India goes down frequently. VLANs also go down frequently. Due to this, the product gets turned off completely, and sometimes, the users go to different traffic. If it’s an on-prem user, they go via a firewall, which increases the pain for the customers. They have a problem with DC. VLANs go down sometimes. That's why the user faces complete disconnection issues for the proxy. Two people in the organization are using the solution.

How was the initial setup?

The initial setup is straightforward. It is just a plug-and-play process. When the Zscaler client is installed on the machine, it works like a normal proxy. They're connected to the cloud. The solution is deployed on all the users’ machines, and the management and policy creation is done at the cloud level. It's a cloud proxy.

What about the implementation team?

The deployment is just a plug-and-play process. The policy is very simple.

What other advice do I have?

We acquired a customer for optimization. Overall, I rate the product a seven out of ten.

Simple to use with easy access and good reliability
Pros and Cons
  • "The solution is stable."
  • "We'd like for them to include some sort of antivirus tool."

What is our primary use case?

We can use the solution for users that are working from home. It allows us to manage control over security. We install an agent and can set the domains that are allowed on the network. It helps ensure security.

What is most valuable?

It can be easily accessed by the cloud. Users can easily work from home while maintaining company security.

The servers are hosted in the cloud, and it maintains security for Azure. It's like having double security - one for the cloud and one for the user.

It is simple to use. We can create multiple tunnels with ease. It's simpler to use than a VPN.

The solution is stable.

What needs improvement?

We'd like for them to include some sort of antivirus tool. It would help if that came bundled with this product from a security standpoint. 

We'd like to have a server connector without ht need for multiple micro tunnels. 

For how long have I used the solution?

We just completed a POC. I just started with the company.

What do I think about the stability of the solution?

The stability is good. The solution is reliable. We've had no issues with stability. I'd rate the stability eight out of ten.

What do I think about the scalability of the solution?

We have almost 300 users.

I'd rate the scalability six out of ten. The policy creation is difficult. It's complicated to add them, and therefore scaling may take a while. 

How are customer service and support?

I don't really deal with technical support. We get support from a third-party vendor, not Zscaler directly.

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

We have used a different solution in the past. Zscaler, we can deploy on VM servers.

How was the initial setup?

We've only completed a POC and plan to roll out a full implementation soon. In the past, I have implemented it completely as well. We are planning to deploy for the sales users first. 

It's not a difficult process. Once the agent is installed, it needs to be verified with the console. The deployment takes between 30 to 45 days, depending on the level of support needed to complete the task. The issue is our sales team are work from home users. That can make the process longer. 

We also need to create user policies before the full deployment happens. Different policies are needed for different users. We may need to create three to four different policies for different user sets. 

What about the implementation team?

We have a third party that we get the solution. 

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

We have yet to receive the cost from Zscaler. We've only done a POC. My understanding is the solution is reasonably priced. I'd rate the pricing eight out of ten.

What other advice do I have?

We are an end-user. We may be a future partner.

It is good for a small environment of 80 to 100 users. I'm not sure if it works for very large organizations. This solution requires less maintenance and makes server access easy - instead of, for example, standalone VPN access.

I'd rate the solution ten out of ten.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Microsoft Azure

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.

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?
