We have four or five big clients that use the solution. 

Scalability is decent. We have been using it for a long time and we don't have any issues with the scalability part of it. It is quite scalable.

There's really no limit to scalability if you have the right hardware and right architecture. I wouldn't put it on the product. It's how you deploy the product. Thousands and millions of authentications are done in seconds and milliseconds, so scalability is not an issue at all.

This product is both stable and scalable. I've seen up to 5-6 million users.

I would rate the scalability as an eight or nine.

It’s very scalable horizontally. We deploy multiple policy servers as we see load increase, and we do have 16 million users.

Whether it's easy or complex to scale will depend on how scalable your enterprise is. If you have multiple data centers, located in multiple places, then it becomes complex to scale. However, if you have a straightforward flow, then the scalability is good. 

I've worked with multiple businesses, some small and others large, ranging from one hundred users to one million users. I know companies who have been using Siteminder for 15 years and others who migrated from Siteminder two years back. Whether they will increase their usage depends on their leadership. If they have already invested money into this, in order to migrate, they would have to invest further, which requires a lot of people. If they see it as a benefit and they think that, by migrating, they can cover multiple other use cases that aren't being covered, then they migrate.

In terms of scalability, so far we haven't really had issues with performance, we haven't faced any problems yet.

It's a very scalable product. From our perspective, we aren't much of a high volume customer and I know that based upon other customers that use the same product, they've been able to see a tremendous amount of growth with the product. We feel very comfortable that CA is continuing to improve it and move forward with the product for us in coming future.

I haven’t seen any performance problems with scaling or general performance ability, so maximum points there as well.

The scalability? I think it does well. We've been able to scale horizontally at various times throughout the lifecycle of the product, within our environment, with minimal fuss. It's been good.

We have a highly-redundant system. We haven't had to do anything else to scale it up any more than what we've already got.

Very easy to scale. They have a good sizing guide it vertically scales very easily.

It's very robust and easy to scale. We were able to scale it within 2 weeks.

I think for SiteMinder, we have a business need and we think it is scalable. For 2016, we'll increase our infrastructure. For the others, we are running them on a minimum hardware set.

We have challenges with scalability. We have a environment in which applications during peak enrollment periods can go from 80 users to 8,000 users in a weekend. Scalability is very difficult with SiteMinder. You basically have to roll out new policy servers and so the ability to provision capacity quickly is still a big challenge for us. They talk about it with every presentation. They're containerizing everything and they're doing all the right things, but they could roll them out faster.

We don't have, and have never had, any scalability challenges.

Scalability is pretty good.

The scalability of this tool is very good.

Once we were familiar with the product, we haven't had any problems with its scaling. We had to figure out the factors that need to be increased so that we can scale up and also elements to look for as far as performance is concerned. We continue to use it more and more, along with an increasing number of applications being brought over.

We've had no issues at all with scalability, as it covers everything we do even at thousands of logins per minute.

It is scalable. It depends on where it's running, and on where it's deployed, and how it's configured. In our case, it is scalable. 

Some parts are scalable, not all parts. We do have some customized pieces within the product itself that we paid CA to build for us. Some of those things are not scalable.

It's very scalable as a self service solution and you can add as many servers as you want, and as many locations as you want. There was a time that we had 20 million customers based on this one solution. It can support a variety of ways, but there is a number of applications, number of users. All of these things really provide very good and easy ways to scale without many changes to the environment.

We have deployed it in a very highly resilient and with a very strong PCM component. Ability to fail over within a datacenter and the possibility of failing over between countries and datacenters. It scales well, we have 200,000 users that's not simultaneous or you are all using it at once but certainly it scales events. There are advanced features that would mean that we need to look at scalability so it does authentication, does also authorization. If there is heavy authorization traffic then we really need to also look at how we scale that up. It can’t scale. It’s just a question of putting in more servers, putting in more infrastructure to allow it to scale.

We are able to scale well with the amount of users that we have and the users that we are supporting. So, it is quite scalable. However, it does not scale vertically. It is only scalable horizontally. Therefore, it increases the footprint.

Right now, we have hundreds of policy servers between two datacenters. If it was vertically scaling, the footprint would have been reduced, and we have been looking towards a solution. However, the SiteMinder platform as such, even the 64 bit, is built on a horizontal scaling architecture. I do not think it is built on vertical scaling. Even if it is, for most of the companies like us, where we invest in a lot of infrastructure, vertical scaling would not really help.

We have it built way above what we need. We have more servers than we need so that we're not impacted if one goes down. We've built in redundancies as well so that there's no single point of failure. We have a highly available system.

It’s scaled up as far as we've needed so far. We're a midsize customer with about 2000 users, and it's been totally fine.

So far no issues encountered with stability.

It is immensely scalable. We have 18,000 employees running on six servers right now. They are not even at 10% usage, but to spin up more just to add a server and plug it in, it is ready to go.

It can scale. You could add more infrastructure. It's very manual.

CA was talking about doing a Dockerized solution, or being able to push out and basically configure new instances of the components. I haven't heard much about it recently.

CA SSO can be scalable, but it's not exactly the easiest thing to do. There is a lot of manual work involved.

It scales. You have to pay attention to its dependencies on the rest of the ecosystem, and especially the directory. That's what's bitten us before; make sure that your directory is responsive, near, and is scaled appropriately for CA SSO.

It's very scalable. Right now we're on the 32-bit version. We need to add more servers and more capacity to handle the loads. I hope the next version will be even better than it is now.

We haven't had to scale really far out yet, but that's coming. We're probably going to double our usage in the next 12 months. That remains to be seen, but we don't really foresee any major problems there.

We have challenges, performance issues for which we’re unable to find the root cause as we scale. But we’re working with CA on this.

Very scalable. You just have to have a central database where all servers hook up to the policy store, and all servers can use the database without a problem. You can then add as many servers as you want.

We are applying the solution to a lot of the platforms we are planning for, and we’re pretty confident and positive that it will be the best solution for us.

We serve about 10 million users all over the country in the US. Scaling it is not a problem as we just add more servers at that point. The one good thing about SiteMinder is that to scale you basically just add more servers. You can piggyback, use the same basic architecture, and just add more.

We are changing the architecture to scale it.

Scalability is also good.

I think there are some drawbacks to the scalability. At a recent conference, we heard that it's going to be a lot easier to scale for larger companies. That's going to be good in the future.

The solution has been scalable.

It has been scalable, to us, at this point in time. It's been able to support quite a number of applications for our client. It's scalable to us.

Symantec Siteminder Is both scalable and stable. If you need to add more groups of members, it's just a matter of adding another web agent. It's very scalable.

No scalability issues.

We're using it on thousands and thousands of devices, thousands and thousands of users. So, it's very scalable.

You can scale it very easily. It works exactly the way the product has been documented. We can scale it well and we did not find any issues with it.

It’s scalable from one app to the next, and we already have the infrastructure built out to support it.

Like the stability, we have had some issues with bringing in new integrations or customizing it for our need. It's been a journey figuring out how to scale it.

It is very scalable. We have a very large customer base: 75 million customers. We have about 40 million log in a day. So, the scalability is very good.

Up until now, there were no scalability issues. We are able to manage around 25K users without any issues.

The scalability is good.

Our customer base is not the largest. It's probably about 10,000 right now. It's scaled fine. There's no problems there. I think we have room to grow if we need to. In terms of the number of applications we have thrown on there, it's grown pretty much exponentially since I started. No problems.

Right now, our load is one million customers and about fifteen thousand internal users. We have web services we use and, this maybe looks so silly, but we didn't really have any major issues with SiteMinder. When my company began in 2003, we had two policy cycles up in production. Now we have six policy cycles. And it's scaled for us without problems.

It's very Scalable. We were able to and we're actually continuing a global roll-out for it across the EMEA region in addition to our North American region, so it scales among all of our Active Directories very easily. We have no qualms in terms of adding users up to hundreds of thousands of users if needed. In terms of scalability, it delivers on its promise.

This solution is scalable.

We have more than 100 users who are made up of engineers and administrators.

Scalability is good so far. It is user friendly, so we are not experiencing many complications when using this application.

There have been no issues. The scale is very important for us because we are doing some new applications.

It scales very well. You can scale it horizontally or increase threads or socket configurations within the solutions.

Scalability-wise it's good. It's built into the product.

No issues encountered.

It’s scalable; you can add new servers and away you go. If we add more users or more load, it’s easy to scale up.

Definitely scalable, no problem here.
