When it comes to scalability it's flexible, absolutely.

The largest network deployment that I've been involved with - we're not a very large company - had about 10 ASAs on the data center side and there were 29 other locations. There were less than 50, as far as the firewall devices go. At the largest deployment, the user count is somewhere a little over 1,000.

Scalability isn't an issue. We had some opportunities we didn't close, a university campus where the deployments were for about 15,000. We scoped it and scaled it out. The licensing gets a little different on some of the products when you go over 10,000 users. Sometimes the product line changes too in terms of design and scope.

It has performed flawlessly in terms of scalability. It has dealt with everything that we've put out there. I have the feeling that it would expand beyond the 30 firewalls we currently have. It does what we need to do with no problems.

If a person has knowledge of how switches and routers work, and that could be a Cisco technician, that would be enough to for scalability using this platform.

I don't see any limitations on the number of firewalls it can handle. We have, on average, about 100 running on it. We have five users.

In terms of features, we're not using the VPN section or the templates so there's room to grow and keep learning the platform.

We haven't hit any limits. We haven't overtaxed it.

We have about 250 firewalls in it, and we're getting ready to add another 250. We'll see how it handles that. That's going to be in the next six months. As we put them in, we'll put them into CDO. Hopefully, we don't come into a point where it says, "Oh, I can't do any more of this," and then we have to reach out to Cisco. I don't even know if there's a limitation on it, as far as how many devices you can have into it. They just added the ability to put Meraki into it. We don't have Meraki but, obviously, you can put more than just firewalls into it.

The only thing that would make me use it more would be if there were an easier way to do changes or upgrades. Right now, there's no benefit to doing changes through CDO; it doesn't save me time.

The scalability is pretty good, with all the features that keep getting added. They're constantly improving it.

We're a fairly small company. We have over six sites, and some of them have multiple ASAs. I probably have about 14 or 15 ASAs on it. There are three guys managing the ASAs. We have about 700 users globally. The biggest site is in San Jose, then Fort Wayne, then Bangalor. The other sites are small sites. And, of course, we have a couple of them in our data center as well.

We never pushed the limits. We put about 15 or 20 firewalls on it, and it seemed to take that just fine.

There are about five or six people who can log into it, look at it, and explore the capabilities of it. To my knowledge, no one is currently using it. If they do, they'll log in there to look at the rule base or for general usage. It was good for getting reports out.

We're on the small end of the scale in terms of environment size. We have four production firewalls and one test firewall, and there are no plans to expand on that. We could use it to manage more firewalls, but those other firewalls are managed by a different team which doesn't want to use the same products that our team uses to manage firewalls. We have the potential, the switches and other networking products, for even bigger savings or integration, but our internal structure prevents it from happening.

Since I only have the four devices I really haven't done anything on a mass scale. I can see us possibly increasing usage in the future.

Scalability is pretty good for a company. We do not have immediate plans to scale much, though we probably will in the future. We work with three firewalls currently. One external firewall and two for the circuits. We have about 800 employees using the system across our organization and scaling from here will be incremental. When we need to we are confident we can scale easily. For example, firewall configuration in the cloud seems like a good idea, so we may take advantage of that — though that may be flexibility rather than scalability.

The scalability of this solution is good.

There are three people who use this solution. We have an administrator, and engineering architect, and a software engineer.

Because it's on the cloud, Cisco Defense Orchestrator can scale up very well.

Cisco Defense Orchestrator is scalable.

We have 1,000 users but we don't plan to increase our usage.
