This query visualises bad traffic (% of emails with threats) compared to total inbound emails over time summarising the data daily.
This query helps in reviewing group Quarantine released messages by detection type. Useful to see what is leading to the largest number of messages being released.
This query visualises the amount of emails subject to an admin policy with action of block, summarizing the data daily
One of the challenges in making an AppLocker policy is knowing where applications
launch from. This query normalizes process launch paths through aliasing, then
counts the number of processes launched from that path, how many distinct machines it
was launched on, and how many distinct file names \ hashes these processes had. The
path is broken into subfolders to help simplify analysis.

This query looks for events that are near in time to a detected event.
It shows how you could avoid typing exact timestamps, and replace it with a simple query to get the timestamp of your pivot event (e.g. a detected event).
This is useful when you have queries that you run often - e.g. as part of your regular investigation of an alert.
Original query: filter for network logon events right before some timestamp.
