Microsoft Security Copilot lists at USD 4 per Security Compute Unit per hour. Sizing the SCU pool against incident volume, threat hunting workflow, and analyst seat counts is the buyer side moves on the next Defender renewal cycle.
Microsoft Security Copilot pricing rests on the Security Compute Unit consumption metric at USD 4 per SCU per hour. The buyer side guide covers SCU sizing, Defender integration, analyst workflow shape, and the commercial moves across the next renewal cycle.
Microsoft Security Copilot is Microsoft's generative AI assistant for the security operations centre. The product sits across Defender, Sentinel, Intune, Entra, and Purview and runs natural language queries against the Microsoft security graph.
Pricing rests on the Security Compute Unit, abbreviated SCU. Each SCU is one hour of Security Copilot compute capacity. Customers commit to a monthly SCU pool that supports the expected workload across all integrated security tools.
This spoke is the buyer side pricing and sizing guide. The audience is the procurement, security operations, and platform team evaluating the Security Copilot commitment inside the next Microsoft Enterprise Agreement renewal cycle.
The SCU is a consumption unit, not a seat license. The unit sits at the centre of every Security Copilot pricing decision.
One SCU is one hour of Security Copilot compute capacity. Microsoft reserves the SCU pool at the tenant level and consumption draws against the pool through analyst queries and automated investigations.
SCU consumption scales with prompt complexity and query depth. Simple queries against the security graph consume less than complex investigations across multiple data sources. Automated investigations triggered by Defender XDR also draw from the SCU pool.
Pool overage runs at the same USD 4 per SCU rate without a discount tier. Microsoft does not throttle Security Copilot at the pool ceiling, so overage consumption flows through the tenant without explicit consent.
Microsoft initially considered a per user Security Copilot license but landed on the SCU consumption model. The SCU model rewards estates with disciplined analyst workflows and penalises estates with diffused or experimental usage patterns.
Pool sizing rests on the analyst workflow, the integration scope, and the automation pattern. Three inputs anchor the right pool.
Count the active SOC analysts, threat hunters, and incident responders who will use Security Copilot in daily workflow. Multiply by expected daily SCU draw per analyst. Typical SOC analyst draws 2 to 5 SCUs per shift across an eight hour window.
Count the expected automated investigations triggered by Defender XDR, Sentinel, and Intune. Each automated investigation typically draws 0.5 to 2 SCUs depending on the complexity and the integration scope.
Run a ninety day pilot across the target analyst pool and the planned integration scope. The pilot telemetry anchors the actual SCU consumption pattern and removes guesswork from the production commitment.
Add a ten to fifteen percent headroom buffer above the documented pilot consumption. The headroom absorbs seasonal incident spikes, new analyst onboarding, and integration expansion across the contract term.
Security Copilot consumption by analyst workflow
| Workflow | Daily SCU draw | Monthly SCU per analyst | Best fit |
|---|---|---|---|
| Routine triage | 6 to 20 SCU | 120 to 400 SCU | Tier one SOC analyst |
| Threat hunting | 10 to 60 SCU | 200 to 1200 SCU | Threat hunter, tier three |
| Incident response | 8 to 40 SCU | 160 to 800 SCU | Incident responder |
| Experimental | Variable | Variable | Pilot users, ad hoc |
| Automated investigations | Per incident | Per volume | Background workflow |
Security Copilot integrates across the Microsoft security graph. The integration surface shapes the SCU consumption pattern.
Defender for Endpoint, Defender for Identity, Defender for Cloud, and Defender for Office combine into Defender XDR. Security Copilot queries the XDR data lake and runs guided investigations through the XDR workflow.
Sentinel SIEM integrates with Security Copilot at the workspace level. Analysts run KQL queries through natural language and Security Copilot translates the intent into the actual query syntax.
Intune integrates with Security Copilot for device compliance investigation and remediation workflows. The integration covers device configuration, compliance posture, and remediation recommendations.
Purview compliance management and Entra identity governance integrate with Security Copilot for compliance investigation and identity threat hunting. The integration covers DLP incidents, sensitive data classification, and identity risk assessment.
Security Copilot use cases concentrate in four workflows. Each carries a typical SCU consumption envelope.
Security Copilot summarises Defender XDR incidents into natural language reports. The use case draws 0.3 to 0.5 SCUs per incident summary and supports faster analyst triage workflows.
Threat hunters use Security Copilot to translate natural language intent into KQL queries across Sentinel and Defender data. The use case draws 1 to 3 SCUs per multi step hunt depending on the data scope.
Security Copilot analyses suspicious file behaviour, script content, and command line activity. The use case draws 0.5 to 2 SCUs per analysis depending on the file complexity and the integration scope.
Security Copilot explains complex Intune, Entra, and Defender policies in natural language. The use case draws 0.2 to 0.5 SCUs per query and supports faster onboarding of new security team members.
The Security Copilot sizing decision is not how many analysts you have. It is how many incidents and hunts they run, and how disciplined the workflow is. The estates that pilot before committing avoid the largest sizing mistakes.
Analyst workflow drives SCU consumption more than the headcount or the licensed scope. Three workflow patterns dominate.
Routine analysts run twenty to forty incident summaries per shift. The workflow consumes 6 to 20 SCUs per analyst per shift depending on the incident volume.
Threat hunters run ten to twenty multi step hunts per shift. The workflow consumes 10 to 60 SCUs per hunter per shift depending on the hunt complexity and the data scope.
Experimental users run ad hoc queries without disciplined workflow patterns. The workflow consumes unpredictable SCU volumes and produces the largest variance in pool consumption.
Security Copilot sits inside the broader Microsoft commercial relationship. Three commercial moves shape the contract.
Run a ninety day pilot before the production commitment. Microsoft offers structured pilot programs that document the actual SCU consumption pattern. The pilot prevents the over commit pattern Microsoft sales motion often delivers.
Negotiate Security Copilot as part of the broader EA renewal rather than a standalone purchase. The renewal context provides leverage that a standalone Security Copilot negotiation does not deliver.
Negotiate burn protection clauses on the SCU pool. Rollover language, swap rights across business units, and downgrade rights for material business changes convert the commitment into a defensive contract.
Security Copilot lists at USD 4 per Security Compute Unit per hour. The pool is committed monthly at the tenant level. Most enterprise estates land in the range of USD 50 thousand to USD 500 thousand per year depending on analyst pool size and workflow shape.
No. Security Copilot is a consumption metric based on the Security Compute Unit. Microsoft initially considered a per user license but landed on the SCU model that rewards disciplined workflows and penalises diffused experimental usage.
Defender for Endpoint, Defender XDR, Sentinel SIEM, Intune device management, Entra identity, and Purview compliance all integrate with Security Copilot. The integration surface drives the SCU consumption pattern across the security estate.
Count active analysts by workflow shape, estimate daily SCU draw per analyst, add automated investigation consumption, and add a ten to fifteen percent headroom buffer. Run a ninety day pilot to validate the sizing assumption before the production commitment.
By default no. Unused SCUs forfeit at the end of each monthly pool period. Negotiate rollover language inside the EA renewal to protect the commitment value across uneven workload patterns and seasonal incident variance.
The product technically runs without Defender or Sentinel, but the integration surface is where the value lives. Estates without Defender XDR or Sentinel typically pilot Security Copilot in parallel with Defender adoption rather than as a standalone purchase.
Negotiate Security Copilot as part of the EA renewal rather than a standalone purchase. The renewal context provides leverage that standalone Security Copilot negotiation does not deliver. Bundle pricing also unlocks broader commitment concessions on Defender and Sentinel.
