Introducing TITAN-Powered Recommendations in Security Copilot Guided Response
In the ever-evolving landscape of cybersecurity, speed and accuracy are paramount. At Microsoft, we’re continuously investing in ways to help analysts make informed decisions under pressure. One of the most powerful of these is Guided Response: a Security Copilot-powered capability in Microsoft Defender that walks analysts through step-by-step investigation and response flows. It provides context-aware recommendations tailored to each incident, enabling teams at all levels to respond with precision and scale. Now, with the integration of Threat Intelligence Tracking via Adaptive Networks (TITAN) recommendations, Guided Response is taking a leap forward. By bringing in real-time threat intelligence (TI) to prioritize and explain suggested actions, it enables analysts to surface, prioritize, and act on the most relevant threats with clarity and efficiency. What is TITAN? TITAN represents a new wave of innovation built on Microsoft Defender Threat Intelligence capabilities, introducing a real-time, adaptive threat intelligence (TI) graph that integrates first and third-party telemetry from the unified security operations platform, Microsoft Defender for Threat Intelligence, Microsoft Defender for Experts, and customer feedback. This graph employs guilt-by-association techniques to propagate known TI labels to unknown neighboring entities (e.g., IP, file, email) at machine scale. By analyzing relationships between entities, TITAN can identify attacker infrastructure before it's leveraged in attacks, giving defenders a critical window to proactively disrupt threats. One of TITAN’s greatest strengths is its ability to learn from indicators of compromise (IOCs) observed throughout the global threat landscape. Microsoft Defender analyzes over 24 trillion security signals every day, across identities, endpoints, apps, and beyond. When a new IOC (such as an IP address, an IP range or an email sender) is identified in one environment, Microsoft Defender rapidly leverages that intelligence to protect other environments. These live, TI-based Guided Response recommendations help identify, manage and block threats before they impact your organization, turning every detection into a defense signal for the entire Microsoft ecosystem. Why bring TITAN into Security Copilot Guided Response? Security Copilot Guided Response already provides analysts with a curated set of recommendations. TITAN enhances this by introducing a new dimension: real-time, threat-intel-driven recommendations that are grounded in global telemetry and threat actor behavior. The integration improves Guided Response by: Expanding coverage to incidents that previously lacked actionable context. Prioritizing recommendations with higher confidence. Surfacing targeted triage and remediation actions based on live threat infrastructure. How it works TITAN suggestions are now integrated into Guided Response as both triage and containment recommendations. When an incident involves an entity with known malicious threat intelligence flagged by TITAN, Security Copilot automatically generates a Guided Response recommendation. Analysts receive prioritized, natural language guidance on how to triage the incident and contain specific threat entities, including: IP addresses IP ranges Internet Message-ID Email senders Real-world impact In early testing, TITAN-powered triage recommendations have shown promising results: Increased model accuracy: TITAN’s integration has helped improve the precision of Guided Response triage recommendations. Improved analyst trust: explainable, threat-intel-backed recommendations, have helped analysts gain more confidence in their response actions. Faster decision-making: TITAN’s real-time scoring and threat attribution have accelerated incident investigation and response times. Evolving Guided Response with threat intelligence TITAN recommendations mark a significant leap in our mission to empower defenders. By combining the scale of Microsoft’s Defender Threat Intelligence with the precision of Security Copilot’s Guided Response, we’re helping analysts move from reactive to proactive— responding faster, working smarter, and acting with greater confidence. Stay tuned for more updates as we continue to evolve this capability. And if you’re already using TITAN recommendations in your environment, we’d love to hear your feedback.

AI-powered insights to accelerate investigation and response When SOC analysts investigate and respond to incidents, Security Copilot offers a comprehensive description of the attack, affected systems, and event timelines, paired with clear, actionable steps for swift remediation and mitigation. Some of our recent innovations include: Enhancement! The Microsoft Sentinel Incident Summary, available in the Copilot standalone experience has been enhanced and now aligns with the Defender incident summaries, offering detailed, step-by-step descriptions of the attack. The summary includes key information such as the attack's start time, timelines, involved assets, indicators of compromise (IOCs), kill chain steps, and a direct link to the incident page. These improvements enable you to request a summary of a Microsoft Sentinel incident from either the standalone or the unified security operations platform embedded experience. Microsoft Sentinel incident summary in standalone experience Enhancement! Users can request Copilot to list incidents in Defender and/or Microsoft Sentinel through a prompt in the standalone portal, filtering by assignment, classification, creation time, determination, last update time, severity, and status. List of incidents In addition, users can also retrieve a list of entities for a specified incident. Figure 3: List of entities for an incident These enhancements allow analysts to efficiently retrieve incidents and entities on demand and apply additional filters for more targeted actions. Enhancement! A recent enhancement to Guided Response enables security analysts to easily communicate with end users, a common activity in the SOC that is particularly helpful for incident triage. Copilot now dynamically generates text for analysts to use, describing the observed user activity under investigation. Analysts can contact the user directly via Teams using the readily available Guided Response recommendation button or copy the generated text to their preferred communication tool. Dynamicallygenerated text for analysts to use This allows for quick and efficient communication with end users, accelerating the incident investigation process and saving the analyst from the tedious task of crafting the message with all the necessary information about the incident. New! During incident investigations, analysts commonly review details about participating assets and entities. In addition to the already available insightful Device Summary, the new Identity Summary provides a comprehensive overview of user identities, highlighting behavioral anomalies and potential misconfigurations. This feature is crucial for SOC analysts as it offers clear, contextual insights into identity-related activities, enabling quicker identification and resolution of security issues. By summarizing key information such as login locations, role changes, and authentication methods, the Identity Summary helps analysts understand the full scope of identity behaviors and risks Figure 5: Identity Summary Enhancement! The script and file analysis features in Security Copilot simplify complex investigations by translating what a script does into natural language and streamlining the analysis of multiple executable files. With the new addition of relevant MITRE ATT&CK techniques to the analysis, SOC analysts can quickly understand the attack tactics and techniques used by adversaries and provide faster and better response. Figure 6: MITRE techniques used Enhancement! The Security Copilot incident report compiles all response activities into a detailed report of the security incident. It includes what happened, the actions taken, by whom and when, and the reason for classification. Initially, the incident report gathered its data from Defender and Microsoft Sentinel, including incident management actions like status changes and assignments, comments from the activity log, actions and playbooks performed on entities within the incident, and more. To further streamline report sharing and provide a more holistic view, the incident report now also integrates with the third-party case management system ServiceNow to include in the report incident investigation and remediation steps logged in ServiceNow tickets. This integration requires the bidirectional connector between Microsoft Sentinel and ServiceNow to be installed.
