The point: ITDR monitors identities directly for threats where classical IAM is blind — particularly in decentralized SaaS services purchased by business units without IT control.
Identity Threat Detection and Response (ITDR) closes a critical monitoring gap for unmanaged SaaS applications that escape classical IAM. This standalone security category detects behavioral anomalies and identity misuse in real time, even without central system integration.
The core problem: Decentralized SaaS and loss of control
The decentralization of software procurement has led to a flood of unmanaged SaaS services that elude central IT control. Business units register directly with cloud platforms, project management tools, and AI services — using business or personal identities, via corporate credit cards or open OAuth interfaces. Classical Identity and Access Management (IAM) such as Microsoft Entra ID or Okta works only with centrally integrated applications. For unknown SaaS instances, central controls are absent: there is no visibility over secure passwords, multi-factor authentication, or whether access for former employees still exists.
Identity as a primary attack vector
The CrowdStrike Global Threat Report shows that the overwhelming majority of cyberattacks abuse legitimate credentials rather than exploiting technical vulnerabilities. The Verizon Data Breach Investigations Report confirms that identity theft via phishing and infostealer malware is the most effective tool for attackers. Criminals compromise simple accounts at unmanaged SaaS platforms to extract sensitive corporate data from there. Traditional identity governance systems do not document these decentralized accounts and therefore cannot protect them.
ITDR as a specialized security function
The analyst firm Gartner has defined Identity Threat Detection and Response as a standalone security category. ITDR fundamentally differs from IAM: while IAM manages legitimate access, ITDR monitors the integrity of the identities themselves and searches for patterns of malicious activity in real time. ITDR solutions combine telemetry data from directory services, endpoints, and network traffic to analyze behavioral anomalies — even without direct integration into SaaS applications. This approach closes the monitoring gap that classical access controls leave behind at unmanaged platforms.
