F5 states that the "brain" of the BIG-IP platform, Local Traffic Manager (LTM) intelligently manages network traffic so applications are always fast, available, and secure.

The Imperva Web Application Firewall (WAF) is based on technology acquired with Incapsula and the former WebSphere WAF.
I mean the only reason we changed away from it was price and it just simply had to do with the licensing that Citrix was offering on the NetScalers. They had basically an all you can eat consumption license that we were easily inside of with all of our VDI usage, whereas with F5 we had to buy the hardware and we had to license the software. Any place you need to actually do traffic balancing at scale, it's a fantastic product. I couldn't recommend it highly enough. There's just some things that hardware SSL offload and hardware load balancing just simply can't be equal that I don't know if there's a better product on the market for that.

I recommend Imperva specially if you have a big environment with thousand of websites because of its ease to use and availability. Imperva delivers a reliable solution with great capability to contain cyber attacks and even fraud preventions in some cases. The only scenario it's less appropriate is if your focus is anti fraud instead of a solution to block cyber attacks.

Sure. It does load balancing fantastically. I mean, it's an industry standard product for that. We also use it for TLS offload for applications. Those are the two main use cases for that. We do also use some of the I rules for traffic filtering. We've used that in some of the external facing services. It does a really nice job with that. It's a little bit complicated sometimes and some of the Cipher Suite stuff is interesting.

Some of the stuff you have to dive into the CLI to really use, I'm going to reach back to the previous employer for this. So I had a much greater degree of involvement with it at that point in time for, I was the crypto guy at the company and I had to design all the cipher suites that we actually implemented on our front end banking products. So in order to do that, I had to dive into it, download all the Cipher suites, figure out the actual order of operation for them, how they were selected because I wanted to design the Cipher Suites to actually provide a specific customer experience for the types of connections that our customers were likely to initiate. Getting at that information was a giant PITA. It was poorly documented at the time. I'm not sure if it's documented any better now. Every time the software changed or got upgraded, made your version, I'd have to do it all over again because the upgrades to the stack, which looked like it was based on open SSL, but it was heavily modified with a different syntax. Oh yay. That's fun too. So I had to write giant documents describing all of the ciphers that I was designing for this because it just kept changing all the time. So I didn't care for that aspect of it. Traffic management does a great job for that.

Attack Correlation Validation - This specific policy produces a lot of false positives as well as the SQL injection policies. Of course it is difficult to tell what a legitimate query is on a public facing web app.
Profiling - I tend to spend more time than any other feature tuning the Web App Profiles. Plugins are used to help cope with this, but on extremely large web apps we are forced to turn off the profiling feature.

F5 has always been one of the best products we have in the data center. We had few issues with the BUG and Code upgrades but the main use cases for F5 was always top notch. From High availability to Globally load balancing applications across multiple data centers and muti cloud environments.

I am very comfortable with this product not only configuring it but automating it as well. There are not many configurations or situations where I do not know how to implement it on the device. I find it straightforward and easy to use.

We haven't needed support from Imperva since implementation. But during that time, their personnel were very quick to respond to questions. Since then, it's been largely doing its thing for us (which is exactly what we'd hoped).

F5 is doing its specialized function. There is no other product that can beat them. We are extremely happy with the product. Especially on load balancing, traffic redirecting TLS encryption, and SNI modification. We will continue to explore F5's product, especially on the public cloud side. e.g. NGINX.

I believe there's no comparison as Imperva is a much more reliable and powerfull WAF. AWS WAF lacks of several features Imperva have and is not that simple to configure neither have a clean web console. I consider Imperva WAF a whole superior level of cyber security solution and it's consider to be one of the leader in this segment.

It has allowed us to let application developers know that the issues are with their application and not due to the network, because of where it sits. This has been invaluable when troubleshooting issues when they arise. Knowing whether or not traffic is even hitting the F5 BIG-IP Local Traffic Manager (LTM), either ingress or outgoing. If the Dev's information is not even making it to the F5 BIG-IP Local Traffic Manager (LTM), we can quickly tell them and let them figure the issue out on their own, saving the rest of the Network Team from getting that 2am call.

Better Insight into web application - Absolutely great, checks all the traffic against RFC standards and will alert on common development mistakes that duplicate application traffic or provide attack vectors for potential attackers.
Have had several issues blocking a customer without producing alerts, while it happened only one week out of 2 years of working with the devices, it did produce a lot of headaches.
