Identity threat detection and response, or ITDR, is a security approach focused on detecting, investigating, and responding to attacks against identities, authentication flows, and identity infrastructure. It matters because modern attackers often target identity systems to gain broad access without needing traditional malware on every device.
What is Identity Threat Detection and Response (ITDR)?
ITDR focuses on suspicious identity behavior such as account takeover, impossible travel, token theft, privilege abuse, MFA bypass, identity-provider compromise, and unusual use of administrative roles. It helps defenders monitor one of the most important control planes in modern environments.
Because cloud apps, SSO, MFA, and federation are central to business access, identity attacks can create an outsized blast radius if they go undetected.
What ITDR Commonly Covers
Common areas include user accounts, service accounts, authentication events, privileged identities, MFA signals, identity providers, directory systems, and risky session behavior.
ITDR vs. EDR
EDR focuses on endpoint activity. ITDR focuses on identity abuse, authentication anomalies, and attacks against access systems and trust relationships. Many organizations need both.
Frequently Asked Questions
Why has ITDR become more important?
Because attackers increasingly steal tokens, abuse SSO, target MFA flows, and move through cloud environments by compromising identity rather than only exploiting endpoints.
Can SIEM handle identity threats without ITDR?
Some identity detection can be built in SIEM, but dedicated ITDR capabilities often improve visibility, context, and response for identity-specific attack patterns.
