The top security challenges organizations face include:

• An increase in the number and sophistication of attacks.
• A talent shortage that is driving the need for automation, integration, and consolidation of security tools.
• Visibility into security, privacy, compliance, and governance.

Organizations need to act quickly to address all the security challenges they face, but working at human speed, even if there weren't a talent shortage, isn't enough. Organizations need to work at machine speed.

Microsoft Copilot for Security is an AI-powered, cloud-based security analysis tool that enables analysts to respond to threats quickly, process signals at machine speed, and assess risk exposure more quickly than may otherwise be possible.

Use cases

Microsoft Copilot for Security focuses on making the following highlighted use cases easy to use.

• Incident summarization - Gain context for incidents and improve communication across your organization by leveraging generative AI to swiftly distill complex security alerts into concise, actionable summaries, which then enable quicker response times and streamlined decision-making.
• Impact analysis - Utilize AI-driven analytics to assess the potential impact of security incidents, offering insights into affected systems and data to prioritize response efforts effectively.
• Reverse engineering of scripts - Eliminate the need to manually reverse engineer malware and enable every analyst to understand the actions executed by attackers. Analyze complex command line scripts and translate them into natural language with clear explanations of actions. Efficiently extract and link indicators found in the script to their respective entities in your environment.
• Guided response - Receive actionable step-by-step guidance for incident response, including directions for triage, investigation, containment, and remediation. Relevant deep links to recommended actions allow for quicker response.

These use cases represent just a few of the capabilities that Copilot delivers and that helps make analysts more productive and also helps up-level them.

Standalone and embedded experience

You can experience Copilot through the dedicated site, also referred to as the standalone experience. Users interact with Copilot through the prompt bar. In the prompt bar, users make requests in natural language and receive response outputs as text, images, or documents.

Additionally, some Microsoft security products embed Copilot capabilities directly within the products’ user interface. This experience is referred to as the embedded experience. Microsoft Defender XDR, for example, enables Copilot capabilities including summarizing incidents, analyzing scripts, generating KQL queries, and more.

More information on both the standalone and embedded experience are covered in subsequent modules. Images shown throughout the rest of this module are based on the standalone experience.

Natural language processing (NLP)

Copilot is built using Azure OpenAI Services and is designed to integrate with existing security tools and processes, making it easier for organizations to improve their overall security posture. Azure OpenAI Services provides REST API access to OpenAI's powerful large language models (LLMs) for natural language processing (NLP), while providing security capabilities of Microsoft Azure.

With access to the powerful LLMs for NLP, Copilot is able to read, decipher, and make sense of human languages, enabling users to securely interact with it using natural language. Although the LLMs are trained on a vast amount of information that endows Copilot with broad general knowledge and problem solving abilities, it’s not enough. Security analysts expect their copilot to be trained on security and that is where the integration with existing security tools and processes comes into play.

Integration with Security-specific sources

Copilot combines powerful LLMs with security-specific sources from Microsoft. These security-specific sources are informed by Microsoft’s unique global threat intelligence, more than 65 trillion daily signals, and incorporates information from a growing set of security solutions using plug-ins and connections to knowledge bases. Through plug-ins, Copilot integrates with Microsoft's own security products, non-Microsoft products, and open-source intelligence feeds. Connections to an organization's knowledge bases gives Copilot more context, resulting in responses that are more relevant, specific, and customized to the user. Through the powerful combination of advanced general models and security specific sources, Copilot is able to learn at machine speed to help analysts identify and respond to emerging threats.

The information you give Copilot will only be accessible to your organization. Your data is your data, and it's protected by comprehensive enterprise compliance and security controls. Your data isn't used to train the foundation AI models.

Microsoft Copilot for Security is the first security product to enable defenders to move at the speed and scale of AI.
