Thanks to the #Derbycon organizers for their time and patience on answering the questions posed.
Missing event issues:
Some issues with missing events… Everyone is affected by this!
WEF & PowerBI is good for small installations.
Any GPOs involved?
Can it be done on a server by server basis?
Can an attacker simply disable the service once initial access is achieved?
Pros and Cons of feeding the WEF output to a MapReduce system?
Not sure if they've used it, but WEF vs. winlogbeat vs. NxLog?
Need a config? Get some examples here for nxlog, winlogbeat, filebeat, Windows Logging Service and other stuff...
