Microsoft Security Copilot in Microsoft Defender Threat Intelligence

Microsoft Security Copilot is a cloud-based AI platform that provides natural language copilot experience. It can help support security professionals in different scenarios, like incident response, threat hunting, and intelligence gathering. For more information about what it can do, read What is Microsoft Security Copilot?.

Security Copilot customers gain for each of their authenticated Copilot users access to Microsoft Defender Threat Intelligence (Defender TI). To ensure that you have access to Copilot, see the Security Copilot purchase and licensing information.

Once you have access to Security Copilot, the key features discussed in this article become accessible in either the Security Copilot portal or the Microsoft Defender portal.

Security Copilot integration in Defender TI

Security Copilot delivers information about threat actors, indicators of compromise (IOCs), tools, and vulnerabilities, as well as contextual threat intelligence from Defender TI. You can use the prompts and promptbooks to investigate incidents, enrich your hunting flows with threat intelligence information, or gain more knowledge about your organization's or the global threat landscape.

• Be clear and specific with your prompts. You might get better results if you include specific threat actor names or IOCs in your prompts. It might also help if you add threat intelligence to your prompt, like:

  • Show me threat intelligence data for Aqua Blizzard.
  • Summarize threat intelligence data for "malicious.com."

• Be specific when referencing an incident (for example, "incident ID 15324").

• Experiment with different prompts and variations to see what works best for your use case. Chat AI models vary, so iterate and refine your prompts based on the results you receive.

• Copilot saves your prompt sessions. To see the previous sessions, from the Security Copilot Home menu, go to My sessions.
