Microsoft Brings TITAN Intelligence System to Security Copilot Guided Response

Microsoft is tightening up cybersecurity triage inside its Defender suite. The company just rolled out a major improvement to Security Copilot’s Guided Response feature—now powered by TITAN, a real-time threat intelligence system built on global telemetry.

TITAN uses machine learning and reputation propagation to flag suspicious infrastructure before it’s used in attacks. In short, it sees bad actors coming.

The system draws on Microsoft’s vast pool of first- and third-party telemetry. Then, it uses guilt-by-association methods to label new entities—IP addresses, emails, files—based on their connections to known threats.

Smarter triage with real-time data

Security Copilot’s Guided Response already walks analysts through response flows. Now with TITAN, those suggestions are far more precise. The tool can suggest when to contain a malicious email sender or block a suspicious IP, based on current global threat behavior.

Here’s what changes:

• TITAN gives coverage to incidents that lacked context before.
• Analysts now get real-time containment suggestions for malicious entities.
• Recommendations are scored, explained, and are easier to act on quickly.

Early results show it’s working

Initial testing shows an 8% jump in triage accuracy, bumping ML performance from 55% to 76%. Analysts also say they trust the insights more, thanks to the clear scoring and threat intelligence backing each recommendation.

Microsoft says this marks a shift from reactive defense to proactive disruption. TITAN-backed recommendations now help teams make faster, more confident decisions in the middle of an attack. As the tool evolves, Microsoft is inviting feedback from analysts already using it.
