Overview
Identity Threat Detection and Response (ITDR) is the fastest-growing IAM category, focused on detecting and responding to identity-based attacks: credential theft, privilege escalation, lateral movement, and account takeover. Gartner named ITDR a top security trend in 2025, recognizing that 80% of breaches involve identity compromise. ITDR combines identity-specific telemetry (authentication logs, directory changes, privilege usage) with behavioral analytics, threat intelligence, and automated response. Unlike traditional security tools, ITDR understands the identity context of attacks.
Why It Matters
Traditional security tools (firewalls, EDR, SIEM) miss identity-based attacks because they lack identity context. When an attacker uses valid credentials, it looks like legitimate access. ITDR detects the subtle anomalies: impossible travel, unusual access patterns, privilege escalation sequences, and credential theft indicators. Organizations with ITDR detect breaches 85% faster and reduce dwell time from 277 days (industry average) to under 30 days. With identity attacks in 80% of breaches, ITDR has become essential.
Key Concepts
1Identity Attack Path Analysis
Mapping the sequence of identity compromises (initial access → privilege escalation → lateral movement → objective) attackers use. ITDR identifies vulnerable paths and monitors them in real-time.
2Impossible Travel Detection
Behavioral detection rule alerting when a user authenticates from geographically distant locations faster than physically possible, indicating credential theft or sharing.
3Credential Theft Detection
Detecting compromised credentials through dark web monitoring, password spray detection, leaked credential databases, and authentication anomaly analysis—often before malicious use.
4Privilege Escalation Monitoring
Detecting unauthorized privilege elevation including AD attacks (DCSync, DCShadow, Golden Ticket, Silver Ticket, Kerberoasting) and cloud IAM privilege changes.
5ISPM (Identity Security Posture Management)
Proactive assessment of identity infrastructure vulnerabilities: weak passwords, stale accounts, excessive privileges, misconfigurations, and attack surface exposure.
6Lateral Movement Detection
Identifying attackers moving between systems using compromised credentials, including Pass-the-Hash, Pass-the-Ticket, and RDP pivoting.
7Account Takeover (ATO) Detection
Detecting when attackers gain control of legitimate user accounts through credential stuffing, phishing, SIM swapping, or session hijacking.
