Yes, I deployed an XTM25 to a smaller business and the company grew beyond what the device could handle VPN wise. There was a trade in process but the company decided not to go with that since it was within a year and the process was not worth their time or effort.

We have not encountered any scalability issues with these firewall appliances.

I have not been in the position to scale up for my customers.

The scalability is fine. We now have around 567 users utilizing this product, but the numbers of users is increasing.

Yes, in the past you could base on the same appliance, in some cases up to three different models. You could grow your performance and capabilities using a license. Now, you need to replace the appliance.

We had a scalability issue. Sometimes when we have heavy traffic, such as 100 mbp/s, we see a high CPU load.

No issues encountered.

Thus far, we have had no scalability issues. We are a call center running about 200 agents on a 50Mb connection, and have plenty of band-width, memory, and processing power.

Scalability depends on a deeper number network and a different number of requirements. We are using a range of network addresses per person here, for the norm, and expecting to boost further without a problem. 

Currently, we have connected about fifteen hundred users with plans to increase the usage. We are expanding. Right now, there is no next product solution upgrade scheduled. 

Most of the competitors to WatchGuard XTM provide the same kind of setup.

No issues encountered.

No issues encountered.

Some boxes provide cluster configurations with up to 16 boxes, and we've never had a problem.

We do not have experience with the scalability of the solution.

Our appliance has a firewall throughput of 2.5Gb/s but if we need more, we have to move to other models until we get to 3.5Gb/s.

The scalability is good. Sometimes we need to buy a better hard drive to run all of the services, but overall it is good.

Never.

No issues encountered.

No.

No issues encountered.

WatchGuard doesn't have a product that allows them to get into the data center. And that's just because there is no hardware to do the job. The software could do it, but there's no hardware that allows that to happen at the moment. So it doesn't scale as well as some other products, that's for sure.

We had issues and raised a case with WatchGuard.

There aren't issue as long the environment is between 200 to 2000 users.

Yes, fallback needs a lot of tweaking to work.

There were no scalability issues. There is 24/7 support from our provider.

No issues encountered.

No issues encountered.

No issues so far.

No, but it depends on the hardware size.
