This is the question. If you’re looking for APM well you’ve got great options but for those using Splunk in the security space (SIEM & SOAR) you’re screwed.
There’s no better SIEM alternative that deals with logs at scale.
Splunk recently screwed a friends Fortune 50 company. They didn't pay a bill on time (renewal negotiations) and Splunk without even contacting them just left all the logs from one of their instances on the floor. They lost everything for literally an entire country.
I mean EVERYTHING.
