Zscaler Internet Access Scalability

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. View full review »

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.

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. View full review »

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. View full review »

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. View full review »

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. View full review »

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. View full review »
