I would rate the scalability of the solution an eight out of ten. 

We have around six to seven customers using this solution. 

The solution is scalable.

The solution scales quite well. 

The appliance can grow only in the stack, but it's not an upgradable design, it is a closed appliance. 

It is unadjustable in performance, in growing or increasing.

It is a scalable product. In my company, we have been able to scale up from level one to level five using Barracuda Web Application Firewall.

My company deals with five or six customers of the product. One customer of my company who uses the product may have around 1,000 users in their environment.

I find this solution scalable.

It is pretty scalable. Because it is a cloud feature, the elasticity comes from the elastic cloud capability, If you make the wrong configurations it is not going to work. We can be working with anywhere between one thousand to twenty-five thousand.

Barracuda Web Application Firewall is a scalable product. Scaling it up isn't an issue.

In our organization, there are around 1,200 to 1,800 users of this solution. 

I rate the product's scalability nine out of ten. It is suitable for enterprise businesses.

I give Barracuda Web Application Firewall nine out of ten for scalability.

I have not tested out the scalability. 

The software is running 24/7.

The product has low scalability, and it is three out of ten. It could be improved.

The solution is scalable.

While the solution may be scalable, I don't have enough background to really comment. I haven't been involved in scaling. 

Scalability with the solution is good. It just requires more licenses, like every other product. If you only apply for the environment, it's scalable with the licenses you have. If you're on the physical appliance, you just have to scale it up by pressing the appliance. It probably won't be just deployed on Azure, because we would need to add more licenses.

We've been adding to our system for a while ago, and we haven't run into any issues with continuing to scale.

I read that you can scale this system by building redundant schemes and using special appliances to manage certificates, but I didn't try it. Therefore, as a manager I don't know, because I didn't try to make a redundant scheme.

Only a few users at our company implement this, but all visitors to our site are affected by this implementation.

This physical appliance is not a solution that scales because once I use it at capacity, I have to buy a new one. The virtual appliance is scalable because if I am at capacity then I can increase my license to another plan.

For the WAF, capacity is not a function of the number of users. Rather, it is based on the servers that it is protecting. Two of my current clients and one hundred and fifty, and two hundred and fifty users, respectively.

The scalability may be okay. However, we have only one Barracuda gateway. We don't really need to scale the solution fight now.

We might have about 500 users within our company using the solution right now.

I'm not sure about the scalability. I would need to explore it more. The most scalable products are likely VMware's NSX, as it is a company that's bit on cloud migration cloud transformation strategies. They'd like to ensure their workloads are safe and secure. I don't see this in traditional RAFs or even firewalls. 

It's difficult to found how many users are on the solution at this time as we use multiple web application firewalls on different applications. It is not every application however, there would be certain applications that would have a WAF. Likely, it's around 10,000 users across applications.

We do plan to continue to use the solution into the future.

The solution is scalable. 

Scalability is good but could be improved. 

Barracuda Web Application Firewall has been scalable in my experience.

I have only the single web application firewall running on-premises, so I cannot comment on scalability other than to say that I haven't had any problems.

We have 18 people who are being protected by this firewall and we do have plans to increase to approximately 100.

We have had scalability issues. However, since we do not have that many applications, it is not an issue for us.

There are no scalability issues.

I encountered issues with scalability.

No issues with scalability.

The scalability has been fine. It's been quite good for us. We don't have complaints in that regard.

We don't really scale it. We have around 500 users. 

We have four clients using the solution.
