Quotes From Members

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

Pros
"The most valuable feature is the DDoS protection, which is the main reason we got it.""The CDN and the WAF features are the best.""The solution can scale extremely well.""The features are powerful and better than F5.""I like that the charges are all based on usage and labor costs. For the time that we spend onboarding almost 252020 FQDN, Akamai charges us only for the traffic usage, but it's only charging us for the labor costs for onboarding."

"Attack prevention is the most valuable feature of this solution.""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."

Cons
"The interface is a little bit clunky and can be improved.""Could integrate more features for each security.""The pricing could be reduced a bit.""Support and the pricing need to improve.""It would be better if there weren't any issues with latency. We had latency issues, but I think they are all solved now."

"Pricing needs improvement.""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."

Pricing and Cost Advice
"Akamai is very expensive.""There is no license at all for Akamai. They are going to charge us only for the usage."

More Akamai Kona Site Defender 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: We primarily use the solution as an application firewall.
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 »
