Database auditing has become simple and easy, releasing storage previously used for native database audit processes. We found new patterns of database users' behaviour and corrected some user authorisations.
Mainframe mappings/agents/optimization for CPU usage are areas with room for improvement.
Agent on z/OS does not have a limit for CPU usage like on other platforms. If
you specify filter too "wide", the agent would consume too much cpu so that
could cause more cost for your mainframe. Agents are a bit special for
configuration because the logic is different than the one on other
platforms.
That is because mainframe agents were originally from Tomium company that
was acquired by Imperva some time ago. They still run the same code, just
little improved.
At this point, my configuration does not collect what I expected, but that
could be due to bugs, that is expected to be solved in version 12 of the
SecureSphere.
You can say for sure that security audit costs money - in this case, your
mainframe CPU money.
I have been using it for 18 months.
We had a problem with mainframe DB2 mappings; incorrect results due to bug. A fix is expected in DAM (Database Activity Monitoring) version 12 in March 2017.
I have not encountered any stability issues. Only, you need to optimize the data/events you are receiving. If you have too much input, you will have a stability problem (in that case, lower event throughput and increase manager memory).
I have not encountered any scalability issues. It's flexible.
Customer service is excellent, 5/5.
We did not previously use a different solution. We had some pilot projects and chose this solution.
Initial setup was straightforward and it was simple/easy to install and customize.
A combination of in-house and local support teams implemented it. We are satisfied with their level of expertise.
ROI is good. We needed this system for getting ISO 27001.
Be careful if you have a mainframe. Calculate well...
Before choosing this product, we evaluated IBM InfoSphere Guardium.
We are very satisfied with this product. It's simple to use, customize and administer. Installation is simple and easy, even on mainframe.
Hi Sudarshan, I am no longer at Imperva, but I agree with you that the legacy console works well, but the UI is dated by today's standard. When I left in the Spring of 2017 there was an R&D project for a new centralized server that would take over some of the legacy console's functionality and add some of the modern elements teams are looking for. It might be worth asking your account manager for a roadmap presentation.
