  • Charges for Log Analytics, Logic Apps and Machine Learning are billed separately on top of Sentinel itself
  • The free allowance is only up to 5 MB per user per day for selected Microsoft 365 security logs
  • Promotional commitment pricing is time limited and locks in only until a stated end date

Octopus Deploy

  • Free tier caps at 10 projects, 10 tenants, 10 machines, 10 users, 5 concurrent tasks and 1 space
