As a cloud-native SIEM, Azure Sentinel offers significant cost benefits. We have seen Azure Sentinel and the promise of cloud-native SIEM result in cost savings, both direct and indirect, for many of our customers. The 2020 commissioned Forrester Consulting Total Economic Impact™ of Microsoft Azure Sentinel study, for example, found that Azure Sentinel delivered a 48% reduction in costs compared to legacy SIEMs, saving on expenses like licensing, storage, and infrastructure costs.
Today, we are pleased to announce changes to the pricing of Azure Sentinel and Azure Monitor Log Analytics that will offer you additional cost savings. These changes take effect on 2nd June 2021.
The changes include:
New Capacity Reservation Naming
Capacity reservations are now called commitment tiers. You will see this change reflected in your user interface, in documentation, as well as on Azure Sentinel and Azure Monitor pricing pages and in the pricing calculator.
New, Higher Commitment Tiers
We are introducing new commitment tiers for both Azure Sentinel and Azure Monitor Log Analytics for higher data ingestion: 1 TB/Day, 2 TB/Day, and 5 TB/Day.
Changes for How We Bill For Data Ingestion Over Your Commitment Tiers
We are also changing the way we bill for overage. Data ingested beyond your selected commitment tier will now be billed using the effective commitment tier rate, instead of the Pay-as-you-go rate, resulting in a lower bill.
For example, for Azure Sentinel in the East US region, if you are on a 500 GB/day commitment tier, you will now be billed for overage at $0.80/GB (i.e. the effective rate for that tier) instead of the $2/GB pay-as-you-go rate.
Simplification of Commitment Tiers
We are simplifying commitment tiers to make them easier to manage. You can now select from eight distinct commitment tiers, per your needs, and no longer need to manage tiers due to minor changes in data ingestion patterns.
As part of this change, any workspaces with commitment tiers greater than 500 GB/day will be reset to the lowest available commitment tier – 500 GB/day, 1 TB/day, 2 TB/day, or 5 TB/day. This change should lower your costs due to the lowered cost of overage.
For example, if you were previously on a 600 GB/day commitment tier, your commitment tier would now be to 500 GB/day. Due to the change in overage billing, on days when you ingest more than 600GB, you would get billed at the 500GB effective tier rate, and on days you ingest less than 600GB, you save money because you are at a lower commitment tier – saving you costs overall.
