It is flexible and lets you easily apply policies, but it needs to support more PoPs

What is our primary use case?

We are using this product for a major airline whose traffic is routed via F5 Silverline Web Application Firewall. All B2C sites are behind F5 Silverline Web Application Firewall. The data part is basically to Akamai for CDNs and to F5 Silverline Web Application Firewall for WAF capability. The resources are hosted on AWS or Azure. For parameters, we have another F5 AWAS module, which intercepts the traffic once it is inside the cloud parameters, and then the data goes to the backend application pool. Every B2C traffic gets inspected on F5 Silverline Web Application Firewall. Every HTTP profile… more »

Pros and Cons

  • "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."
  • "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."

What other advice do I have?

You should know what you're actually blocking. A lot of customers move to WAF or AWAF because they were told to do that, but they need to identify what they're actually looking to inspect. For example, one of the clients I worked with did not understand the differences in capabilities between a next-generation firewall and a WAF. When I say WAF, I am talking about AWAF, not the previous generation WAF. No one considers that anymore. People who try to put WAF and think that they are secure are not really secure. There is still a fine grain of security that you need on a next-generation…
