The Imperva WAF acts as our go-between (proxy) for our public-facing websites. They intercept known bad actor IPs, and we can also block certain countries that have shown to be problematic and we don't do business in. More dynamic attacks are also detected and blocked, making this largely a "fire and forget" tool. We rarely even need to log into the tool, except to pull our weekly reports.
  • Block some dynamic attacks such as SQL injection.
  • Block unfriendly accesses based on geographic source.
  • Helps us implement SSL in cases where the original server can't (yet).
  • The UI can use a little work (but is largely decent)
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.
  • Our on-prem firewall has less work to do, allowing it more cycles for other tasks.
  • We have better web traffic visibility and control over what actors are doing outside our network.
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.
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.
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).

SecureSphere has been purchased mostly due to either a major concern around protecting web applications or adhering to PCI compliance. It provides great insight into web applications outside alerts and can be used not only by the security unit but the applications teams as well.
  • 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.
  • 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.
If you are looking for a cheap product to meet the bare minimum requirements for PCI or any other compliance regulations, this is not the product. Also, the WAF portion only inspects on HTTP/HTTPS traffic which can be very limiting into other forms of web apps that utilize other protocols.

The HTTP/HTTPS inspection that it does do is very in depth and well worth the investment.
  • 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.
