How to Use Microsoft Security Copilot in 2026: Step-by-Step Guide

Microsoft Security Copilot is an AI-powered security platform that combines GPT-4 with Microsoft's threat intelligence to help security teams investigate incidents, understand vulnerabilities, and respond faster. It integrates with Microsoft Sentinel, Defender, and Entra.

Microsoft Security Copilot is one of the most significant AI deployments in enterprise security — an LLM-powered assistant built on GPT-4 and trained on Microsoft's threat intelligence, which covers 65 trillion signals per day from Microsoft's global footprint.

What Security Copilot Does

Security Copilot acts as an AI analyst in natural language: investigate incidents, summarize alerts, explain what a script does, and recommend response steps. Unlike generic LLMs, it's grounded in Microsoft's real-time threat intelligence and integrated with your actual security tools.

Integration with Microsoft Security Stack

Security Copilot integrates natively with:

  • Microsoft Sentinel (SIEM/SOAR) — investigate incidents, run KQL queries in natural language
  • Microsoft Defender (endpoint/identity/cloud) — triage alerts, understand attack chains
  • Microsoft Entra (identity) — investigate suspicious sign-ins and permissions issues
  • Intune, Purview, Defender for Cloud — unified security posture questions

This native integration means Security Copilot has actual context about your environment — not just generic threat knowledge.

Threat Intelligence Grounding

Security Copilot is grounded in Microsoft Threat Intelligence, which tracks 300+ threat actors, monitors 50+ ransomware groups, and processes 65 trillion security signals daily. When investigating an incident, it can identify which known threat actor a technique matches and what their known objectives are.

Skill-Based AI

Beyond natural language, Security Copilot includes Promptbooks — pre-built investigation workflows that run in sequence. Common use cases: vulnerability impact assessment, reverse engineering malicious scripts, phishing email analysis, and incident post-mortems.

Pricing

Security Copilot uses a compute-unit pricing model (Security Compute Units, SCUs). Provisioned through Azure at approximately $4/SCU/hour. Enterprise deployments typically provision 1-5 SCUs for analyst teams.

What You'll Need

  • A Microsoft Security Copilot account (starting from $4 (usage-based))
  • A modern web browser or the Microsoft Security Copilot app
  • Payment method for paid features

Getting Started

1

Create Your Account

Visit https://www.microsoft.com/en-us/security/business/ai-machine-learning/microsoft-security-copilot and sign up for a usage-based account. You'll need an email address to register.

2

Start Your First Conversation

Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. Microsoft Security Copilot supports incident-investigation, threat-intelligence, kql-natural-language, alert-triage, vulnerability-analysis, script-analysis — start with a simple text prompt to get familiar.

Pro Tips

  • Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
  • Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
  • Use examples: Show Microsoft Security Copilot what format you want by including an example in your prompt.
  • Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.

Troubleshooting

Responses seem generic or unhelpful
Add more context to your prompt. Specify the audience, tone, length, and format you need. Try starting over with a clearer description of your goal.
The tool isn't responding or is slow
AI chatbots can experience high traffic. Refresh the page and try again. Check the service's status page if issues persist.
Output is too long or too short
Explicitly specify the length: "in 100 words," "as a brief summary," or "in detail with examples."
