Microsoft Sentinel costs $2.46-$5.20 per GB ingested depending on commitment level. Pay-as-you-go is $5.20/GB. A 100 GB/day commitment reduces cost to $2.96/GB (43% savings). The first 10 GB/day is free for 31 days, making it ideal for trials and small deployments.

02 Does Microsoft Sentinel have a free tier?

Yes, Microsoft Sentinel offers 10 GB/day free for the first 31 days. After the trial, pricing switches to pay-as-you-go or commitment tiers. Organizations already using Microsoft 365 E5 get some security data included, reducing additional Sentinel costs.

03 What are the hidden costs of Microsoft Sentinel?

Hidden costs include Log Analytics storage ($0.12-$0.15/GB/month), data egress fees ($0.01-$0.09/GB), Azure Monitor charges, professional services ($10K-$50K+), training ($1K-$3K per admin), and potential costs for premium data connectors.

04 Can I save money with commitment tiers?

Yes, commitment tiers offer 43-52% savings. Committing to 100 GB/day reduces cost from $5.20/GB to $2.96/GB. A 1,000 GB/day commitment drops to $2.46/GB. Calculate your average daily ingestion and commit at 80% of typical usage for optimal savings.

05 Is Microsoft Sentinel included with Microsoft 365?

No, but Microsoft 365 E5 licenses include Microsoft Defender data at no additional cost, which can reduce Sentinel ingestion charges. Core Sentinel pricing still applies for all other security data sources. Integration between Defender and Sentinel is seamless for E5 customers.

06 Microsoft Sentinel vs Splunk: Which is cheaper?

Microsoft Sentinel is typically 50-70% cheaper than Splunk for similar workloads. Sentinel at 100 GB/day with commitment costs ~$9K/month ($2.96/GB) vs Splunk's ~$5,750/month for 100 GB/day plus infrastructure. Sentinel's cloud-native model eliminates hardware costs.

07 Are there hidden costs beyond the per-GB pricing?

Yes. Users report several hidden costs: (1) Premium support costs approximately €99/month for meaningful technical assistance, (2) Azure Log Analytics workspace storage and retention fees (15-30% additional), and (3) data egress charges when moving data out of Azure. One user noted encountering unexpected fees that 'blindsided' them beyond the advertised pricing.

08 What happens if I don't pay for premium support?

Without paying approximately €99/month for priority support, users report being redirected to support staff who may not adequately understand or resolve technical queries. Multiple reviewers describe this as a significant barrier to getting help with the platform.

09 Can I cancel Microsoft Sentinel easily?

Users report difficulty canceling Azure services and removing payment methods, describing complex multi-step processes that can take up to a month. Additionally, Microsoft Azure has a policy where accounts with invoices overdue by 90+ days are automatically deleted, including all stored data.
