What is Zscaler SASE?

For the last 30 years, networks have been connecting users to applications in the data center, which was surrounded by a secure perimeter to keep apps and data safe from the outside. But with applications moving to the cloud, IoT becoming more common, and users connecting from everywhere, network security is no longer able to solve the fundamental challenge of security and is instead adding significant complexity and cost.

Zscaler SASE Pricing Advice

What users are saying about Zscaler SASE pricing:
"It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable."

Easy to deploy, use, and manage, but needs more granularity and control over the interfaces and better licensing and support
Pros and Cons
  • "I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."
  • "It has massive room for improvement. The Zscaler product itself is okay, but it doesn't give enough granularity for us as an organization to stipulate rules or processes, especially for data-driven services. For instance, we can stick on SSL inspection, but it's just a click box. It doesn't allow us to go any further into the detail of the SSL inspection. We also can't pull it out without having an additional logging server. It just doesn't give us enough granularity. They should give us more control over the interfaces because it is all backend. They weren't very open to discussing their backend architecture with us in terms of their own data centers. They can maybe a little bit more open about what components are there and how the backend infrastructure works alongside Zscaler. Its licensing can be better. Some of the additional licensing costs are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Their support should also be improved. I initially had a consultant from Zscaler for its deployment, but the support that I had throughout the deployment of the project wasn't the best."

What is most valuable?

I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. 

It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway.

What needs improvement?

It has massive room for improvement. The Zscaler product itself is okay, but it doesn't give enough granularity for us as an organization to stipulate rules or processes, especially for data-driven services. For instance, we can stick on SSL inspection, but it's just a click box. It doesn't allow us to go any further into the detail of the SSL inspection. We also can't pull it out without having an additional logging server. It just doesn't give us enough granularity. 

They should give us more control over the interfaces because it is all backend. They weren't very open to discussing their backend architecture with us in terms of their own data centers. They can maybe a little bit more open about what components are there and how the backend infrastructure works alongside Zscaler.

Its licensing can be better. Some of the additional licensing costs are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. 

Their support should also be improved. I initially had a consultant from Zscaler for its deployment, but the support that I had throughout the deployment of the project wasn't the best.

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

We weren't using any other solution.

How was the initial setup?

It is very easy. There were some constraints trying to deploy the access gateway and the endpoint client to some of our regions due to processes being blocked. They gave a list of processes that need to be allowed through ADM endpoints and our sort of antivirus products so that they're not scanned, and they're allowed through to function. However, I had some issues in following the guide and trying to get them initially deployed and allowed through. The firewall has to be off regardless of whether the port allocations were opened or not, but this could potentially be a regional issue. Other than that, the deployment was very easy.

What about the implementation team?

I went through a subsidiary company of Zscaler. I initially had a consultant from Zscaler themselves, but the support that I had throughout the deployment of the project wasn't the best. They were very much technical sales as opposed to technical consultants. I myself had to work through and resolve a lot of issues that I faced during the deployment and setup.

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

It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable.

What other advice do I have?

What I would say is that try it, test it, and ensure that it sort of meets the company requirements. We were lucky enough to go through an extensive trial period. Zscaler, unfortunately, only allows a two-week trial regardless of where you are with the setup. They only give you coverage for a very basic setup. You have very limited time for trying anything further or trying the product as if it was in the production environment. Therefore, I would advise scoping out what you want and how you want to achieve it as quickly as possible. After that, you can really hammer home when you go through the initial deployment to ensure that it works and meets all the requirements.

We are now looking at Cisco Umbrella. We are a Cisco house predominantly, and Cisco Umbrella just interlinks with our VPN solution and our overall architecture. We're looking to migrate to a Meraki SD-WAN fabric because it allows us to just use that network overlay underneath the secure access edge and just incorporate it into what we already have.

I would rate Zscaler SASE a seven out of ten.

Excellent scalability, good performance, and very nice private access features
Pros and Cons
  • "The scalability of the solution is great."
  • "There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."

What is our primary use case?

Increase performance, stability and Secure Remote access for Remote Users. 

What is most valuable?

Two great features that we really like on the solution are the Internet Access and Private Access. The path solutions available that help protect the customer's internet access and ensuring B2B secure access are great.

The scalability of the solution is great.

The solution offers very good performance.

What needs improvement?

Due to the fact that it's a multi-tenant hosted environment, it should be noted that other solutions, like Palo Alto, are single-tenant solutions. It's the customer that's hosting it, it's a single tenant. Zscaler hosts a SaaS solution and a multi-tenant, not a single-tenant environment. It would be nice if they offered that as well. This is where probably Zscaler can differentiate itself.

There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors. These things only come up when you're talking to enterprise customers who are really looking at those things. For smaller to mid-sized customers, Zscaler makes more sense. These things make it cheaper and more efficient, as well, for Zscaler. 

For how long have I used the solution?

I am actually a technical field engineer. I make solutions that help customers with different products. I don't use it personally. I sell it to different customers. 

What do I think about the scalability of the solution?

The scalability of the solution is top of the line. It's one of its great selling features. Users can scale easily if and when they need to.

In terms of how many people use it typically, it depends on the company size. If you're like the last one I worked with, which was an enterprise customer, you can have five, 10, even all 5,000 users that, especially here in COVID times, are working remotely. It depends on the size of the organization and depends on the roles of people who need the secure access. 

An enterprise customer who has 5,000, 10,000 users, for example, will find that most of the users who need secure access to it, depending on the data you're hosting, will be at about 50-60%. They may not be on it one time, but that's where the licensing will be. At least 50-60% of the users, or the workforce in the company. This will only increase due to the COVID times when people are working more remotely.

How are customer service and technical support?

I personally have never used technical support. However, I also haven't heard any complaints from customers in relation to the level of support they provide. It must be okay if we haven't heard anything.

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

I also sell Palo Alto as well.

I have been selling Zscaler, however, I only have had hands-on experience in Palo Alto. I don't have answers yet on Zscaler. The last hands-on experience I had on any device was two and a half years ago when I was more involved. I am just technical sales now. 

How was the initial setup?

I haven't deployed the solution yet myself.  I wouldn't be able to comment on the process. I don't know if it's complex or straightforward.

That said, from what I've seen in customers that have deployed it, I've never really heard a bad comment from anyone who is using it.

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

I'm not a direct customer, so I don't know what the exact cost of the solution is, on average. It would depend on the company's size.

What other advice do I have?

We're a Zscaler partner.

When you implement Zscaler, you're actually utilizing the best of what the technology has to offer. 

I've only heard good things about the solution. I'd rate it eight out of ten.

Cloud security, built-in scalability, and professional technical support

What is our primary use case?

Our role is as consultant, architectural, and pre-sales. Rather than purchasing new VPNs and other architecture, our clients use Zscaler SASE to allow their workers to work from home due to COVID. 

How has it helped my organization?

It decreases the overhead that they are running when it comes to licenses for the VPNs and allows them to merge multiple technologies, such as the VPN capabilities, and the CASB solution.

What is most valuable?

The most valuable features of this solution are the CASB solutions, which is protecting their Office 365.

What needs improvement?

The interface needs a bit of work. It could be a little more streamlined and more intuitive.
