It's scalable.

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.

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.

It's scalable.

The solution can scale very well. 

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. 

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

Scalability-wise, I rate the solution an eight out of ten.

My company has 200 users using 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.

It is easy to scale. Additional sites and licenses can be added quickly and easily.

It certainly scales to what we have asked it to do so far. We have over 50,000 users on it without a single problem.

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

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. 

The scalability is perfect. I would give it a ten out of ten.

Zscaler Internet Access is scalable.

It is a scalable solution. It is easy to scale and secure remote users. If a company hires 100 more people, I don't think it would be a problem.

The largest environment, which I reviewed, had 2000 employees.

It's scalable and easy to expand. 

We have multiple clients that use the solution. We have between 8,000 and 50,000 clients. 

The solution is scalable, we have around 70,000 total users across various environments.

Zscaler is a cloud-based solution, so it's scalable. 

Zscaler Internet Access is scalable but it depends on the licensing model you choose. It can scale very easily.

We have approximately 1,800 users using the solution in my company. Everyone in the company is using the solution, from receptionist to corporate employees.

Zscaler Internet Access is scalable. 

I have not had any issues with the scalability of Zscaler Internet Access. I have not encountered scalability issues, but my company has not scaled up that much to encounter problems with scalability, so I can't really comment on how scalable the solution is.

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.

We have more than 1,000 people using the solution. 

The scalability is really good. We've had no issues with the scalability. We even don't know when the performance tuning is happening in the back end. The user is not experiencing any problems, even if all thousand-plus users have started using it at the same time. There's no slowness or lag which is experienced.

We use it on a daily basis and plan to increase usage in the future. 

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. 

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. 

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.

The scalability of Zscaler Internet Access is good.

One of the primary features of Zscaler is that it's obviously infinitely scalable. That's one of the reasons we like it. It takes away the bottlenecks that we've seen in appliances historically. You can typically grow quite fast.

As long as the platform that they have, that we're connected to, is scaled property, which is their responsibility, then it should be very good. We did hit a problem a while back where they didn't scale properly and we had some major issues. We just hope that it'll never be repeated. It's all about how they manage it, however.

We have about 80,000 users right now. We're selling to more customers, so we're trying to double that number in the next 18 months.

We have around 1,000 users on the solution. 

We do not have plans to increase usage. 

This is a very scalable solution. 

Zscaler Internet Access is very scalable, and requests for scalable solutions are met quickly.

The question of scalability would be best posed to our CSO. However, my whole team uses it. It's been scaled in our organization to a very small extent. In that sense, it was easy to scale. 

I don't know the maximum capacity, however, it's my understanding that the solution is suitable for organizations like us with about 3,000 employees.

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.

The scalability of the tool is pretty good. I rate the scalability a nine and a half or ten out of ten.

Scalability-wise, everything is good. We have approximately 3,000 users and we do plan to increase usage. Ultimately, we want to include everyone, which is about 10,000 users.

Its scalability is fine.

The solution is very scalable. If a company needs to expand it, it can do so. It's on the cloud, which makes scaling easy.

There are no issues there. The number of users doesn't matter, whether you have 100 users or 2,000 users. The only impact you'll have is on financial side. For 100 users you will pay differently than 10,000 users, so I don't think you have an issue on this side.

All our users have libraries on their computers. So if they have a device from the company, they have Zscaler on it. I think we have about 3,000 users in my company.

We have one or two people on maintenance from the global networking team. You don't need to do something special, it just works. The only thing we need to do is check daily if there are any threats, as well as to verify the US dollar and stuff like that. In terms of maintaining it, doing something to make it work, you don't have to worry about that. It's a cloud provided solution. The only thing that you have to concentrate upon is the business side. You have to see how your business is affected, what type of traffic you have in there, and check security threats on your site. That's it. The product by itself is run by the Zscaler team and they do a good job. We do not have maintenance debts. The only incidence that I remember is last month they were blocking our site or something , but that was solved quickly with support from Zscaler.

For Zscaler, it is scalable for anywhere from five users up to 5,000 or 10,000 users, because of the MSS model when at telco providers. For an individual company, it is still quite easy for them to scale, based on how much hardware or cloud services they want to deploy. It's pretty easy to scale, as the organization scales.

In general, if you want to look at the number of users, this solution can deploy anywhere from five users up to 10,000 users quite easily from an MSS model, managed services model. When you talk about an on-prem model, however, scaling needs to be deployed at phases. It cannot be deployed in one go for anywhere from 1,000 to 3,000 users. It has to go through a deployment phase.

I think it scaled quite well. We are currently using it in a small organization with about 250 users, and I would say it will scale as our company grows. 

Zscaler is very easy to scale.

In my company, we have around five thousand users, but just the main account would be around three thousand. 

It works every day and it's protecting against the attacks and so we are using on a daily basis.
