F5 BIG-IP vs. Imperva Web Application Firewall (WAF)

I really do think it's well suited for any placement on the edge, especially with the WAF portion. APM is a whole different module unto itself that allows for VPN Connect connectivity, web top access. So it really is for these modules anyway, an edge appliance for us and not really usable in the interior of the network.

Imperva web application firewall does a great job in giving us control over access to our public web servers. With our regular hosting provider, we couldn't block access based on geography, or really anything. So we had to rely on traditional access controls to protect the data. But with the WAF, we can block countries such as North Korea, or we could stop any SQL Injection attempts, or even do a temporary block of IP in the case of detected brute-forcing.

• Easy connection: you can connect to your corporate network with two clicks.
• IP restriction: F5 has a list of possible insecure IP numbers, if someone tries to connect using one of these numbers, F5 BIG-IP won't connect.
• Always on feature: Very handy feature, if you install always on, you won't need to click connect.

• Alert Aggregation - Correlates different violations into perceived correlated attacks.
• Ease of deployment - as one of the only WAFs that allow bridge mode deployment, this can be deployed with without downtime and no Network Architecture modifications. If the need for proxy is required at a later time, Transparent Reverse Proxy can be deployed within seconds and minimal configuration.
• Custom Policies - Custom security policies are easy to configure.
• Reporting - There are a good amount of pre-configured reports available by default.

• I think the policy configuration that had some improvements on the ASM word things, improvements may be on the signatures that would be good because it's a little bit confusing on the ASL, how they are updated and deployed, and this staging. So that's something that could be.

• The UI can use a little work (but is largely decent)

There are just a couple of points that are hard to find, that probably could be elsewhere. But these are minor; everything else is right where you'd expect it to be.

On the occasions when we've had to engage f5 support, they have been great. They have always resolved our issues quickly and been easy to work with and professional. The reason I give them a 10 out of 10, however, is because when we've had issues that have crossed over between the f5 BIG-IP, our Cisco switches, and our Microsoft IIS server the f5 support representatives have been extremely knowledgeable about every product and device involved and have been able to troubleshoot end-to-end without having to engage other vendors.

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).

implementation is fine

F5 BIG-IP is my first F5 product that I have stared to work, and it brings me more experience doing a lot of migration upgrades from old code version to new code. The way F5 has all configuration help us to develop scrips to improve our process.

Ultimately, it was the easiest to work with that was still a "known" company (we've been burned too many times by up-and-comers). We needed something that gave us a lot of control but then didn't need its handheld on a daily basis. Imperva gives us a lot of that and we are still able to navigate it with ease.

• Having a load balancer of F5 helps to address large traffic limit on organisation's application
• This means that organisation gets a lot of revenue due to the usage of their application
• Hence provide a very positive impact onthe inverment or ROl of the organisation

• Meet compliance requirements - Check.
• 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.
