Commitment Tiers in Microsoft Sentinel are well named: if you commit to a certain amount of ingestion capacity every day then there are different tiers of discounted pricing. Historically, the lowest tier has been a commitment of 100 GB a day, but there’s a new 50 GB tier in public preview with promotional pricing until March 31, 2026. Customers who sign up during this period will lock in promotional pricing until March 31, 2027.
