The web proxy feature blocks malicious sites so that end users don't inadvertently get compromised
Pros and Cons
  • "All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
  • "It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work."

What is our primary use case?

We leverage it for web proxy and web security.

How has it helped my organization?

All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none.

What is most valuable?

Generally, the web proxy feature blocks malicious sites so that my end users don't inadvertently get compromised.

What needs improvement?

It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work.

The logs that are consumed by our security solution could be a bit more definitive, from an audit perspective. It's sometimes difficult to determine which end user a particular generated alert is associated with.

For how long have I used the solution?

One to three years.

What do I think about the stability of the solution?

Stability is good. We have a presence around the globe, it's very localized and that minimizes any kind of latency. Even though they still complain about it.

What do I think about the scalability of the solution?

Scalability is good. Right now our internal workforce is around 120. I have no plans to increase the usage for now. They do have some features we don't use currently.

How are customer service and support?

Technical support is effective.

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

In the past, we did use some other products. We used OpenDNS which subsequently became Umbrella. Zscaler is easier to manage than OpenDNS but now I think that product is even.

How was the initial setup?

There is a short learning curve on the setup, so it's not complex, but it's not necessarily trivial either. The entire deployment took two to three hours. 

We have about 1.5 persons who manage all of our internal IT apps.

What about the implementation team?

We did the implementation ourselves. 

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

There aren't any additional costs to the standard licensing fees.

What other advice do I have?

Pay attention to the Zscaler recommended best practices. Don't try to figure it out on your own. Go with what they say to do.

I would rate it an eight out of ten.

It is a perfect solution for organizations that have a lot of road warriors.
Pros and Cons
  • "Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
  • "Tech support is good."
  • "The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."

What is our primary use case?

The primary use case is for organizations that have a lot of road warriors or very highly distributed small offices. It provides protection anywhere you are...whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere.

How has it helped my organization?

This solution helps you establish a secure connection from your laptop to the closest Zscaler point of presence. So, you have protection anywhere in the world. That's the advantage of it. You don't have to VPN all the way to your home office if you're half-the-world away. You go to the closest Zscaler connection and get your policies applied there. Its very powerful. Its great for anybody who has a lot of distributed work force, a lot of work from home people, or a lot of road warriors, that is where Zscaler shines.

What is most valuable?

The most valuable feature is the Zscaler protection from external threats. It scrubs everything, email, worms and root problems from websites. It is protection, particularly for distributors users and road warriors. Its very good. They're rated highest in secure web-data wise.

For how long have I used the solution?

One to three years.

What do I think about the stability of the solution?

I do not have a problem with the stability of the product.

What do I think about the scalability of the solution?

It is scalable. You can easily put new users and offices on it. It is cloud-based, so you do not run into a hardware limitation like you would with other products.

How is customer service and technical support?

We used tech support when we first set up the solution. It was good.

How was the initial setup?

It was very straightforward. Anyone with firewall familiarity will find it a simple process to download this solution.

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

The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market.

Which other solutions did I evaluate?

We have made comparisons to Palo Alto and Cisco Miraki.

What other advice do I have?

The solution's great, but you have to put it into context because of the pricing and the way it basically protects the device from anywhere. It is really more meant from highly distributed organizations, for organizations that have a lot of work from home and those with road warrior workers. That's what it is designed for.

There is a single panel where you can configure the policies for your entire organisation worldwide
Pros and Cons
  • "Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality."
  • "One on the main benefits is protection all time from anywhere."
  • "In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
  • "​After a proper implementation, the maintenance is very low.​"
  • "​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
  • "Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."

What is our primary use case?

Zscaler provides web security on the cloud for any device at any place all the time. If you use local appliances, users are not protected when they are connecting from outside the corporate network (e.g., home office, hotspots, airports, etc.).

We use Zscaler from all our locations, and for our roaming users too. In order to integrate our users to Zscaler, we use Okta (ADFS) for authentication, cloud security connectors for traffic redirection from locations (tunnels to the Zscaler cloud), and the Zscaler app for roaming users. 

How has it helped my organization?

One on the main benefits is protection all time from anywhere. 

Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality. 

In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide and the reporting tools are brilliant.  

What is most valuable?

Zscaler provides a lot of features in terms of control (URL filtering, cloud app control, etc.), which can be found in other solutions as well, but in terms of security, it is quite unique. SSL inspection, Advanced Threat Security, and Cloud Sandbox are probably the most valuable. 

  • SSL inspection is easy to implement and the performance is great (it is the responsibility of Zscaler to provide it). 
  • Advanced Threat Security protects you from most threats that can bypass the classic anti-malware solution.
  • Cloud Sandbox completes the stack of security requirements stopping zero-day malware.

What needs improvement?

Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful.

For how long have I used the solution?

More than five years.

What do I think about the stability of the solution?

When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. 

How was the initial setup?

After a proper implementation, the maintenance is very low.

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

Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).

No need to maintain multiple devices on the data center and secure entire traffic.

Valuable Features

Zscaler is securing entire cooperate traffic using its different modules. This includes URL & aapplication filtering, malware & threat protection, bandwidth control, sand boxing and advanced fire-walling etc. Specifically, I like the URL filtering/user authentication. DLP and firewall features are also an added advantages. Also, there are various traffic forwarding mechanisms such GRE, pac file, VPN etc.

Improvements to My Organization

Since this is a cloud based product, we don't have to bother about the hardware/physical status and space. No need to monitor and manage the hardware. If there's an issue, Zscaler will switchover to another node to process the customer traffic.

Room for Improvement

Using location admin users should be better so we can merge any centralized authentication servers like AD, Radius, and any other server. This would help centralize the server management. v5.2 is being released shortly, and will have a lot of new features for TLS and HTTPS transactions.

So the SSL inspection is done at the IP level and not at the application level (with a transparent Web proxy for instance) with ZScaller. Do you have any information regarding the pros and cons of doing SSL inspection at the IP or HTTP level? What about the necessity to deploy a CA certificate at the client side? Is it mandatory?
