I assessed SAP, Sybase, Db2, AIX, and MDM before switching to ArcSight Analytics.

We did not evaluate other solutions as through research we could tell the product was well accepted and had the solutions we needed.

We looked at Splunk and HelpSystems. There were a few more vendors but I don't recollect all their names. Because of the number of integrations that ArcSight has, it was more applicable to our use case.
