Identity Threat Detection and Response (ITDR) refers to a set of security practices and technologies designed to detect, investigate, and respond to threats targeting digital identities within an organization. These threats often involve compromised credentials, privilege escalation, or unauthorized access to sensitive systems. ITDR solutions work by continuously monitoring identity-related activities, analyzing behavior patterns, and identifying anomalies that may indicate malicious intent. Once a threat is detected, ITDR tools help security teams respond quickly by isolating affected accounts, enforcing multi-factor authentication, or initiating automated remediation workflows. As identity becomes a primary attack vector in modern cyber threats, ITDR plays a crucial role in strengthening an organization’s overall security posture.
Gartner defines user authentication as the journey-time process that provides credence in a claim to an identity established for a person for access to digital assets. User authentication is delivered by some combination of (a) an authenticator, (b) signals evaluation and (c) an authentication decision point, which may be from different vendors.
