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.

YOUR CHALLENGES

Attackers don’t
break in.
They log in.

Identity remains one of the top access vectors for ransomware. In the past year, Sophos X-Ops has observed the number of stolen credentials offered for sale on one of the dark web’s largest marketplaces has more than doubled.

Increasing attack surface

Identities now extend far beyond the network perimeter, encompassing cloud users, automation, and AI agents. Weak non-human identity management is linked to 41% of identity breaches.

Complex IAM tools

Identity and access management systems are difficult 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 take advantage of compromised identities to gain unauthorized access to sensitive data and systems.

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.

Sophos ITDR uses AI-driven risk scoring to continuously evaluate every identity — human and non-human — and surfaces the highest-risk findings with contextual reasoning that explains why each finding matters, based on that user’s history, role, and behavior. It connects to identity sources including Microsoft Entra ID or Microsoft on-premises Active Directory to continuously monitor the environment. Sophos ITDR also analyzes the behavior of Microsoft AI agents in your environment, extending identity security to your agentic environment. In the background, it performs more than 160+ posture checks and identifies issues like exposed credentials, misconfigurations, and risky authentication activity.

Yes. Sophos ITDR includes AI-driven identity risk scoring, which continuously evaluates every identity and surfaces the highest-risk users and accounts. It also leverages AI infrastructure to analyze posture findings in context — explaining why a finding represents a risk based on that user’s history, role, and behavior. Sophos ITDR also monitors the behavior of Microsoft AI agents, extending identity protection to your agentic environment.
Non-human identities include service accounts, automation scripts, and AI agents that operate with user-level or elevated privileges. They are increasingly targeted by attackers because they often have broad access, are less actively monitored than human user accounts, and may not be subject to the same access policies. Sophos ITDR provides visibility into non-human identities alongside human users, helping you identify misconfigurations and risky access patterns across your full identity estate.

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.
Sophos threat intelligence also reports that the number of stolen credentials offered on dark web marketplaces have increased sharply over the past year. This steady rise highlights how identity has become one of the most reliable and cost‑effective attack paths for adversaries.
Sophos ITDR delivers ROI 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

By detecting and containing identity threats early, organizations can prevent high‑impact breaches that often lead to multimillion‑dollar remediation costs, business disruption, and long‑term reputational damage.
ITDR protects against the full spectrum of identity attacks, including:
1. Compromised credentials and account takeover.
2. Privilege escalation and lateral movement.
3. MFA fatigue and token theft.
4. Password spraying, brute-force, and kerberoasting attacks.
