The short version

  • Only Microsoft Sentinel has a free tier, so it costs nothing to try first.
  • Each has a real cost: MetricStream implementation typically costs one and a half to two and a half times the first year licence, so a one million dollar licence carries a one and a half to two and a half million dollar rollout that rarely appears in the initial business case.; Microsoft Sentinel billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets
  • They diverge on capability: MetricStream covers Enterprise and operational risk, Microsoft Sentinel covers AI-powered analytics.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MetricStream

  • Implementation typically costs one and a half to two and a half times the first year licence, so a one million dollar licence carries a one and a half to two and a half million dollar rollout that rarely appears in the initial business case.
  • Full deployment takes six to eighteen months, during which the organisation runs old and new processes in parallel and the promised efficiency gain is negative.
  • Per-user pricing in the low thousands per year per seat discourages giving access to the first line of defence, which is precisely where risk data originates, so many deployments end up with data still arriving by spreadsheet.
  • Configuration flexibility comes at the price of specialist skills, and organisations become dependent on MetricStream partners or a small internal team, making later changes slow and expensive.
  • The interface and workflow feel enterprise-heavy next to modern compliance tools, and infrequent business users find it hard, which suppresses the participation the platform is meant to enable.

Microsoft Sentinel

  • Billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets
  • Commitment tier discounts require reserving daily ingestion capacity in advance, and a tier cannot be downgraded until 31 days have passed
  • Commitment tiers start at 100 GB per day, above what smaller estates ingest
  • 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

Six to eighteen months for a full platform deployment, and the services cost usually exceeds the first year licence.

MetricStream: Is it right for a mid-market company?

Usually not. Its depth suits organisations with several regulators and formal three lines of defence structures.

MetricStream: Does it replace SOC 2 automation tools?

It can cover the framework, but it is not designed for the automated evidence collection those tools do cheaply.
