What is Identity Threat Detection and Response (ITDR)?

Identity Threat Detection and Response (ITDR) protects organizations from attacks that target user identities instead of specific hardware or software. Today's attackers don't need to break in - they log in using stolen credentials, misused privileges, or compromised sessions.

Why is ITDR critical in modern cybersecurity?

Identity has become the primary attack vector in cloud-first environments. Sophos Incident Response found that 95% of Entra ID environments contain critical misconfigurations, creating opportunities for privilege escalation and account compromise. Traditional controls such as identity access management (IAM), multi-factor authentication (MFA), and periodic audits aren't enough. ITDR delivers continuous visibility into identity posture and risk, closing gaps before attackers can exploit them.

How does Sophos ITDR work?

Sophos ITDR is an add-on for Sophos Extended Detection and Response (XDR) for higher fidelity detection and enables rapid containment or Sophos Managed Detection and Response (MDR) providing optional analyst led investigation and remediation, including actions such as disabling accounts, forcing password resets, and revoking active sessions. It connects to identity sources such as Microsoft Entra ID to continuously monitor the environment. In the background, it performs more than 80 posture checks and identifies issues like exposed credentials, misconfigurations, and risky authentication activity. Sophos ITDR then correlates this identity telemetry with the broader security signals already gathered in Sophos XDR. This improves detection accuracy and helps teams investigate threats faster.

What differentiates Sophos ITDR from other ITDR vendors?

Sophos ITDR combines continuous identity posture management, dark web credential intelligence, and behavioral detections in one AI powered platform. It provides detection coverage mapped to 100% of MITRE ATT&CK Credential Access techniques and integrates natively with Sophos XDR and the world's most trusted MDR service. Most vendors detect. Sophos detects, correlates across your environment, and enables rapid response, with optional 24/7 analyst led containment through Sophos MDR.

How is ITDR different from IAM, MFA, or traditional audits?

IAM and MFA control who can access systems, but they don't detect misuse after someone has already authenticated. Traditional audits only provide point-in-time snapshots that quickly become outdated. Sophos ITDR continuously monitors identity posture, detects subtle misconfigurations, exposed credentials, and session abuse, and enables immediate containment through built-in actions or MDR intervention. It closes gaps that static tools leave behind.

What is the ROI of ITDR?

A significant portion of modern cyber incidents originate from identity compromise. Sophos Incident Response and Managed Detection and Response investigations consistently show attackers using stolen credentials, privilege escalation, and identity misuse to gain initial access and move laterally inside environments. ITDR improves return on investment by reducing ransomware entry points tied to credential abuse, lowering incident response and recovery costs, minimizing operational downtime, continuously reducing identity misconfigurations before they can be exploited, and offloading investigation and response to 24/7 Sophos MDR experts when enabled.

Increasing attack surface

Identities are no longer confined to the traditional network perimeter. The shift to cloud and remote work has increased the complexity of monitoring and securing the identity attack surface.

Advanced IAM tools

Identity and access management systems are challenging to manage, with numerous and constantly evolving settings, policies, and configurations that threat actors target to gain access and elevate privileges.

Prevalence of stolen credentials

Cybercriminals exploit compromised identities to gain unauthorised access to sensitive data and systems.

Frequently asked questions

Sophos ITDR is fully integrated with Sophos Extended Detection and Response (XDR) and Sophos Managed Detection and Response (MDR), the world’s largest Agentic SOC. Identity threat detections are automatically escalated to Sophos security analysts, who investigate and execute response actions on your behalf — locking accounts, forcing password resets, and revoking active sessions.
Identity Threat Detection and Response (ITDR) protects organizations from attacks that target user identities instead of specific hardware or software. Today’s attackers don’t need to break in — they log in using stolen credentials, misused privileges, or compromised sessions. ITDR also covers non-human identities such as service accounts and AI agents, which increasingly operate with user-level privileges and can be exploited as attack vectors. It helps organizations reduce their identity attack surface and respond to threats with speed and precision, with full coverage of MITRE ATT&CK Credential Access techniques.
