Exposing the secret Office 365 detailed activity logs and forensics tool
I looked at the API calls on the CrowdStrike blog post and I have been using parts of these API's for calls in PowerShell for at least the past year for tracking down issues we have had in Office 365.   I can understand how frustrating it can be if your competitors seem to have "secret knowledge".  However that knowledge may have been gotten by calling up the very helpful people at MS support, laying out the problem and they send you a Powershell script in return.
