Microsoft Security Copilot Review 2026: Features, Pricing, Pros & Cons
Microsoft Security Copilot brings generative assistance and specialized agents across Defender, Sentinel, Entra, Purview, Intune and related Microsoft security products. Analysts can summarize incidents, investigate identities, create queries and use agents for recurring security and compliance work. In 2026, qualifying Microsoft 365 E5 and E7 packaging can make adoption more accessible than the original standalone capacity model.
Open official website01Current product and version
Version checkedSecurity Copilot agents and Microsoft 365 E5/E7 inclusion, 2026
Microsoft-centric organizations that want one AI layer across security operations, identity, data protection and device management.
Security Copilot ranks third because few competitors cover as many security domains inside one widely deployed enterprise ecosystem. It is strongest when Microsoft already holds the relevant telemetry and permissions.
Included capacity and agent availability vary by agreement and region. Broad permissions create broad risk, so role design, logging and data boundaries are essential.
How this review was researched: This is a research-based review, not a claim of a private laboratory test. We checked current official product pages, documentation, release notes and pricing or plan information where available, then assessed workflow fit, maturity, access, control and implementation risk.
02Where it performs well
Works within familiar Microsoft security consoles and workflows.
Specialized agents can assist with high-volume repeatable tasks.
Security, identity, compliance and endpoint context can be combined.
Microsoft 365 packaging may improve economics for qualifying customers.
03Limitations and risks
Less attractive when core telemetry sits outside Microsoft products.
Licensing and capacity rules remain complex.
Generated KQL, summaries and recommendations can be wrong.
Tenant permissions and data residency need close governance.
04Pricing and access
Pricing depends on Microsoft agreements, Security Compute Units and included Microsoft 365 entitlements. Confirm which agents and workloads are included, how capacity is pooled and what happens after the allowance is exhausted.
05Who should choose it
Choose it when Defender, Sentinel, Entra and Purview already form the security backbone. Evaluate each agent with least privilege, representative multilingual data and a documented human-approval path.

07Frequently asked questions
Is Security Copilot included with Microsoft 365?
Microsoft has announced inclusion for qualifying E5 and E7 customers, but capacity, timing and exact entitlements must be checked in the organization’s agreement.
Can Security Copilot take response actions?
Some workflows and agents can support actions, subject to product integration and permissions. Organizations should require least privilege and human approval for consequential steps.
