We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

More Cloudflare Pros »

"It's a good front end for public infrastructure""Attack prevention is the most valuable feature of this solution.""The most important feature is that they have seven firewall protection, to protect our web servers.""The most valuable feature is flexibility.""Its flexibility is the most valuable because it is a managed service. The good part is that you don't need to set it up. It just needs DNS routing, which is the easiest thing. Our client had Akamai for certain websites because they were using CDN features. They had NetScaler on the internal zone, F5 AWAFs on the data centers, and no WAF at all in the cloud. One of the main activities of the project was to move all these policies into a single WAF so that we could control and use that as a choke point. That exercise itself was very easy because it was a managed service and F5 Silverline Web Application Firewall does that for you. That's the best thing about F5 Silverline Web Application Firewall. It is easy to apply policies on-premises. If you have AWAF on-premises and you want to replicate some policies on F5 Silverline Web Application Firewall, other than the policies that it applies by itself, it is easy because you have a team that supports it. F5 Silverline Web Application Firewall works perfectly fine. It pretty much does everything that an Advanced WAF on-premises should do."

Cons
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration.""There should be a specific price list for enterprise-level customers.""The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful.""Technical support is lacking.""There are some issues with the CDN services.""The solution could work at being less expensive. It costs a lot to use it.""Latencies are always a problem.""Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."

"The price is high in comparison to other products.""Pricing needs improvement.""I just hope the price can be cheaper.""We need to have support for cloud protection, which is not offered by this solution.""F5 Silverline Web Application Firewall, being a new product in the market or comparatively related to a new product, currently supports less number of PoPs. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."

Pricing and Cost Advice
"The cost primarily depends on the size of the organization.""We don't have any issues with the price.""The price is reasonable."

More Cloudflare Pricing and Cost Advice »

"F5 Silverline Web Application Firewall works based on your bandwidth. They look at the clean bandwidth and do the pricing. 20% of a total pipe would be a clean bandwidth. The list price or a non-negotiated price for F5 Silverline Web Application Firewall would be around $2,200 per application per year for everything that you need. When you get into an enterprise kind of a setup, they negotiate this to the last bit. I would easily take 20% on that, which would be the cost, but it should cover all your Advance WAF features, bot protection, tech campaign, etc. It is built as a package and gives you most of the capability. You don't get the mobile SDK, which is an additional license. Mobile SDK is required only if you're buying or if you have a mobile application, and you are going to instrument F5 or Imperva into your mobile appliance. This anyways would be an additional module. It doesn't come within the WAF, but it is a WAF feature."

Top Answer: For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.
