Quotes From Members

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

Pros
"The most important feature is that they have seven firewall protection, to protect our web servers.""The most valuable feature is flexibility.""F5 technical support is really good.""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."

"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well.""The most valuable features for us are the DDoS and Bot.""The solution's most valuable aspect is that it is easy to configure.""It is an effective threat mitigation tool.""The technical support is excellent.""It blocks all types of attacks.""Simplifies putting everything in code.""DDoS protection and WAF are the most valuable features. It is easy to deploy a service. It is easy and quick to deploy to a new website."

Cons
"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.""In terms of the scalability, this part is always so confusing because they are checking for packet count. Also, after an attack, they said that the throughput must be from gigabits but then I check my bandwidth and it is already done in gigabits. So it is a little bit confusing.""We need to have support for cloud protection, which is not offered by this solution.""I just hope the price can be cheaper."

"I would like to have support for SSL management and secure DNS.""Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers.""The rules surrounding the making of web applications could be improved.""Imperva should have more points of presence in Africa.""A limited tool if you're looking to customize.""It's quite expensive.""Its price could be improved. It is quite expensive. It will be good if we could export the configuration. Currently, to control the configuration, we need to go to each website, which is not very convenient.""The log analytics interface within Incapsula isn't really good. For example, if you have to get all logs from there, it's a very cumbersome process."

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."

"It is not expensive compared to the other similar solutions in this category.""It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic.""It is expensive.""The cost is on par with other solutions such as Cloudflare and Akamai.""The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."

Questions from the Community
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. 
Top Answer: I highly recommend Cloudflare. We switched from Akamai Prolexic to Cloudflare and couldn't be happier. We also got the worlds fastest DNS and speeded up our site load times with the 200+ edge… more »
Top Answer: Simplifies putting everything in code.
Top Answer: This is a very limited tool if you're looking to customize. It would be helpful if Imperva would provide additional resources for Terraform that can easily be deployed. There are some cases where… more »
