Imperva Web Application Firewall (WAF) vs. SAP NetWeaver BPM

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.

It is well suited when we need to integrate business processes with SAP ERP and SAP CRM - the solution can be integrated with business rules/procedures defined in SAP ERP/CRM and NetWeaver can be used to monitor the rules and flag off exceptions. When there are multiple workflows running, it tends to slow down running of these processes. Also, it entirely depends on SAP portal for it to run efficiently.

• 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).

• Virtual paper trail. Iterations of process and current documentation are all stored as "artifacts", leaving a great trail.
• Configuration of users. BPM somewhat magically determines which users will be impacted and automates rules.
• A pro (that is also a con) is the design interface. If you know what you are doing, it is incredibly powerful and malleable.

• 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.

• Live readings would be nice.
• Easier to maneuver
• Work with all systems with the press of one keystroke

As a big fan of SAP in general, the BPM solution fits right in with all the other things SAP does well, and does it with incredible efficiency

It's easy and works great. The onboarding process, although easy, can sometimes take too long for SSL and domain validation, but its not a big deal.

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).

We have our own tech support for systems, I would say they probably could use more training on it, I don't really think it's anything regarding the SAP system, but more the knowledge they have on the system itself. It seems to take longer for them to fix any issues we may come across.

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.

I found the initial setup of NetWeaver is much simpler than other products especially in an SAP environment where we have SAP ERP/HRM/CRM as it can be well integrated with other SAP products. The only drawback is the need/dependency on SAP Portal. It is better suited in an environment where SAP ERP is running.

• 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.

• Helped us harness integrated benefit from having SAP ERP/CRM by leveraging NetWeaver to define business processes/rules and monitor exceptions
• Did not have any negative experience except for the fact that at times when multiple rules run, it can be somewhat slow
