When it comes to scalability, Imperva Web Application Firewall could use some improvement. I would rate the scalability as a seven out of ten. Three people use the solution at our company.

I would rate the scalability an eight out of ten. 

Scalability-wise, there is one issue we encountered that I want to mention. At some point, Imperva, moved their account takeover prevention features from the on-premises edition to the cloud-based edition, and we discovered that this step would take yet another integration, seeing that we were using Imperva on-premises. These account takeover prevention features, however, were already part of our subscription, but since the features moved to the cloud, we missed out on them. So, in this sense, I would say the scalability strategy isn't as solid as it should be, and for this reason I would rate the scalability a 3.5/5.

On the other hand, when it comes to how many users we were able to scale up to, we actually had the whole organization using it, including around 3,500 clients in total.

It scales very well. I would rate it a nine out of ten for scalability.

In terms of traffic volumes, being a distributor, we do not face the issue of many customers flooding our website. It is not like an e-commerce company. At peak hours, there is almost 500 Mbps of network traffic. That is it.

Scalability-wise, it is not so scalable as the solution is quite straightforward. There's not much you can scale with the solution.

Mainly, the IT department uses the solution and there are ten to 20 of them.

In terms of scaling, Imperva Web Application Firewall is amazing. The product is really good so far.

We have very few users with direct usage - 10 users approximately.

There is zero maintenance.

I would rate the solution's scalability a nine out of ten. We have more than eight to nine sites that are covered by the tool. 

Scalability is very good.

The solution is scalable. We have 20 applications hosted on its on-premises version and around five applications on mobile infrastructure. A team of three administrators manages the operations.

Right now, it depends on the company and its needs. I can't speak to if there are plans to increase usage.

The scalability of the Imperva Web Application Firewall is good.

Imperva is scalable.

The solution is best suited for enterprise-sized businesses. It is a scalable solution.

The solution in my experience has been scalable. In my organization we have approximately 10,000 users using the solution, the whole company uses it.

Scalability is affordable. There are no issues with the process of scaling.

They have centralized management, in terms of scalability. They have centralized policy control, they have centralized application profile information. On the dashboard they have Signature Update, Monitoring, Reporting. They clearly thought about the large-scale when they made this product.

It is a scalable solution. I would rate it a nine out of ten. 

The stability of the Imperva Web Application Firewall is good.

We have approximately three or four clients using this solution.

I rate Imperva Web Application Firewall's scalability an eight to nine out of ten. 

I rate the tool’s scalability a ten out of ten. Imperva allows only clean traffic. The scalability is based on the clean traffic and not the overall bandwidth of the client. Our clients are mostly enterprise businesses. I have some SMB customers.

I think Imperva Web Application Firewall is scalable. 

The cloud version of Imperva Web Application Firewall is very scalable.

If you build this solution properly then you have scalability.

The solution is very scalable, but of course, the scalability comes with a cost.

The product is scalable, and my company has 20,000 users. One administrator manages the tool. 

We typically deal with medium-sized organizations.

The licensing model makes the solution very simple to scale. If a company wants to expand, it's not a problem.

Imperva is a Gartner leader, so its scalability, performance, and features are excellent.

Cloud-based deployments offer easy scalability. On-premises scaling is more complex because it depends on our hardware; we have to mount some servers and specific requirements.

We have around 10 to 15 customers. 

We implemented the SA solution and have not tried to scale it beyond our client's 10,000 users. 

It is for large-scale enterprises where the traffic is huge, and there are many internet-facing applications, which is a plus point of Imperva.

We don't have the HA mode for the respective solution in Imperva, which has to be there when we have the DC and DR locations. We can activate only one solution at DC, but while we are conducting the drills between DC and DR, it is quite difficult to import all the configurations at the DR location in Imperva. It takes time.

Scalability capabilities are well thought through by product development. Installation of additional MX servers and gateways on remote networks ensures coverage of scanning and data usage monitoring/data protection capabilities.

The tool is scalable. 

The solution is scalable.

I had no issues with scalability.

The solution can scale.

We typically deal with medium-sized enterprises as clients. Typically, these companies have around 500,000 or so employees. They aren't massive, however, they are quite sizeable. 

Imperva WAF is scalable.

The solution is scalable and is currently being met with high demand on the clients side.

It is easy to scale. The scalability is fine. You can add gateways and scale, which is a good feature in Imperva.

This device is suitable for everyone.

No issues with scalability.

It’s an ongoing process day to day, working alongside systems and application engineers to adapt the WAF to better meet the applications characteristics. I guess it depends a lot on the application features and software implementation.

It is easy to scale up.

Scalability of this solution is based on the design. If you get your design right, then you shouldn't have a problem with the scalability.

I have not faced any trouble with scalability because you can easily upgrade the appliance. 

Scalability is good especially compared to IBM. It's not so easy to integrate with another solution from another vendor. 

The solution is scalable, however, in terms of scalability, you're required to change the appliance, as it's not like a cloud, which is easier to scale. I would not rate it very well when it comes to scalability, because a model of license-based upgrades would be better. They could give you a bigger box to make it easier to grow if you needed to.

We haven’t had any scalability issues.

The solution is very scalable. It is one of the most important features. You can also expand resources and features as well.
