We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
"F5 technical support is really good."
"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."
"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."
"Compared to other web application firewalls in the market, Imperva does things in the most accurate way."
"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
"Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."
"The most important feature I have found to be the ease in how to do the backup and restores."
"The solution has been quite stable. I have not seen any bugs at all."
"The solution can scale."
"The solution is stable."
"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."
"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."
"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
"I think that better bot protection is needed in this solution."
"The user interface could be better."
"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"Sometimes our web application firewall will slow down."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"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."
"The cost of this solution depends on the platform."
"The price of this solution is a little bit high compared to competitors."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
"There is a license for this solution and we purchase the license annually with no additional fees."
"There are a couple of different licensing models."
