F5 Distributed Cloud WAF (Web Application Firewall) vs. Imperva Web Application Firewall (WAF)

It is doing its job effectively, and its scalability is superb. So, if you have a mixed environment with cloud and on-premise systems to protect this product, provide a solution to the challenge. However, its management is more suited to DevOps teams rather than to the ones responsible for on-premise systems, making the management a bit more complex.

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.

• Layer seven attacks are becoming far more common. Traditionally it was always layered three, layer four, where you get an additional firewall, but with the application layer attacks become more frequent, more popular, et cetera. So having the web application firewall protecting us, and then with the recent Log4j, that's the most recent use case when it gave us that instant level of protection whilst we remediated the Log4j that we had that and the F5 Distributed Cloud WAF was protecting us.
• I have a great relationship with the account manager, my account manager, and I think he drives the best price possible, um, for me, and I'm happy with that price.
• F5 Distributed Cloud WAF is always innovating and evolving.
• We run a very competitive proof value where we run numerous competitors against each other, and then we evaluate from that and then make the selection, and F5 Distributed Cloud WAF was the winner.

• 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.

Incentivized

• Lack of warnings, currently the console does not provide a warning when deleting key-value entry.
• The web GUI could use some tweaking, currently no undo option when removing exclusion rules.
• Configuration complexity, currently menus and options are hidden, making it hard to configure vs on prem.

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

We gave it an 8 because it protects our web apps well and is reliable. The WAF is flexible and meets most of our needs. It could improve in user interface and make integrations easier, but overall, it’s a solid and effective security tool for us.

I believe is a solution that was designed from the start to be simple and easy to use. Coming from Imperva, it simply eased the burden and complexity of managing and securing our apps on different environments (cloud and on-prem). It easy to scale and very quick to deploy (as a cloud waf should be), provide us with DevOps integrations, visibility and automatic insights from multiple events that guarantee peace of mind for us analysts and opp managers.

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.

Seems no issue

Unnoticed slowness

I never contacted support for this product.

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).

Online training saves me lots of time

Just make sure you origin servers have F5 IPs allowed.

The other one that I've used in the past, they're very similar and I haven't used it recently, so I can't do a side-by-side comparison today. But I can say that F5 does everything we want it to do consistent with what this other product did do and it's got enhanced features and of course we have a long history with F5 as a product set in general.

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.

Dont see any issue so far

• The biggest gain for us was speed. Before F5 Distributed Cloud WAF, onboarding a new app to our WAF stack meant manual rule tuning, traffic sampling and regression testing. Right now, we spin up a service, tag it with the right policy and its ready (production ready) within hours

Incentivized

• 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.
