Overall Satisfaction with Imperva SecureSphere

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.
  • 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.
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.
