Introduction to ITDR
Identity threat detection and response (ITDR) is a cybersecurity discipline focused on detecting, investigating, and responding to threats targeting identity systems like Active Directory (AD) and Entra ID, identity providers (IdPs), and authentication mechanisms. It enhances traditional identity and access management (IAM) by introducing threat intelligence, behavioral analysis, and automated response capabilities to mitigate identity-based attacks.
Why Identity Security Is Now a Top Priority
With extensive cloud adoption, remote work, and the explosion of SaaS applications, attackers are increasingly targeting user credentials and identity systems rather than networks or endpoints. In fact, research reveals the following key facts:
- Credential theft is now the primary attack vector in breaches.
- Compromised identities are used to escalate privileges and move laterally.
- Attackers regularly exploit misconfigured or unsecured components of the identity infrastructure.
The Emergence of ITDR as a Cybersecurity Category
Organizations often have a variety of traditional security tools in place, including security information and event management (SIEM), endpoint detection and response (EDR), and extended detection and response (XDR) solutions. However, these tools struggle to detect identity-based threats in real time.
ITDR has emerged as a distinct and critical cybersecurity category that fills a vital gap by:
- Providing context-aware visibility into identity misuse and anomalies
- Detecting misconfigurations, privilege escalation and unusual access behavior
- Automating threat response workflows (disabling accounts, alerting security teams, etc.)
- Integrating with other security tools to enrich threat detection and response
Gartner’s Recognition and Definition of ITDR
Gartner formally recognized ITDR as a distinct cybersecurity discipline in 2022 and now highlights ITDR as a critical component of a modern security strategy.
Gartner defines ITDR as a collection of tools and best practices to defend identity systems from threats such as credential misuse, privilege escalation and lateral movement.
Common Misconceptions about ITDR
| Misconception | Reality Check |
| ITDR stands for IT disaster recovery. | ITDR stands for identity threat detection and response. |
| ITDR is just another IAM tool. | ITDR is not a replacement for IAM. While IAM tools control and secure access, ITDR is about detecting when identities are misused or compromised. |
| Traditional security tools already cover identity threats. | SIEMs, EDRs and related tools lack deep visibility into identity threats (such as suspicious changes in Active Directory or abnormal token usage), making ITDR essential to fill the gap. |
| ITDR is only for large enterprises. | Identity-related attacks affect organizations of all sizes. Every entity uses an identity infrastructure like Active Directory, Microsoft Entra ID or Okta, and therefore requires an ITDR solution. |
| If multifactor authentication (MFA) is enabled, identity is secure. | MFA is not foolproof. Attackers have developed techniques like token theft, MFA fatigue attacks and session hijacking that can circumvent MFA. ITDR helps detect these tactics. |
The Role of Identity in Modern Cybersecurity
Identity is now the linchpin of cybersecurity. Defending digital identities with robust identity detection and response tools is essential for reducing risk and strengthening organizational resilience.
Digital Identities: The New Perimeter
In the traditional security model, the network perimeter was the primary boundary to defend. However, with the rise of cloud infrastructures and remote access, that boundary has dissolved. Today, digital identities — such as user accounts, service accounts and machine identities — have become the primary control point for access to systems, data and applications.
Every interaction with enterprise systems now starts with an identity and involves authentication, authorization and access provisioning. As a result, protecting identity infrastructure is not optional — it is foundational.
Key Trends Driving Identity’s Critical Role
| Trend | Description |
| Cloud adoption | As organizations migrate workloads to public cloud platforms (such as AWS, Microsoft Entra and Google Cloud) and adopt SaaS tools, identities become the central means of access. Misconfigurations, excessive permissions and lack of visibility into cloud identities open attack vectors. |
| Remote and hybrid work | The shift to remote work has led to a huge expansion in endpoint and access diversity. Employees connect from unmanaged devices and personal networks, further elevating the importance of secure and monitored authentication. |
| Identity sprawl | Organizations today manage thousands to millions of identities across different platforms — users, admins, third-party vendors, IoT devices and services. This sprawl often introduces: Inconsistent policy enforcementOrphaned accounts and stale credentialsGreater attack surface for credential-based threats |
Key Statistics on Identity-Based Attacks and Breaches
- 80% of security breaches involve compromised credentials or identity misuse, according to Verizon’s 2024 Data Breach Investigations Report (DBIR).
- Microsoft reports 1,287 password attacks per second as of 2022, and their data for 2023 shows that this trend is continuing.
- Gartner predicts that by 2026, 90% of organizations will experience an identity-related breach — yet only a fraction of companies currently monitor identity behavior in real time.
- In a 2024 IBM study, stolen or compromised credentials were the most common initial attack vector, and the average breach cost exceeded $4.6 million.
ITDR Explained: Core Purpose and Benefits
ITDR is dedicated to safeguarding digital identities by monitoring and defending identity systems, rather than focusing on network or endpoint activity. Its core purpose is to:
- Protect critical identity infrastructure
- Detect misuse or compromise of identities, such as credential theft and privilege escalation
- Spot anomalies in identity behavior, such as login attempts from unusual locations and excessive access requests
- Enable swift response to identity-based threats, thereby limiting attacker dwell time and damage
Proactive vs. Reactive Identity Protection
There are two critical layers of defense in securing digital identities.
Proactive protection focuses on hardening identity environments before an attack occurs. It includes practices like:
- Enforcing least privilege access
- Implementing MFA and conditional access
- Routine credential hygiene (for example, rotation, vaulting)
- Continuous identity posture assessments
Reactive protection (enabled by ITDR) focuses on detecting and responding to active threats targeting identities. For instance, it includes:
- Alerting when service accounts are abused
- Identifying lateral movement via credential theft
- Automatically revoking tokens during suspicious activity
Together, they form a comprehensive identity security posture.
ITDR as a Complement to IAM, SIEM, EDR and XDR
ITDR fills a gap by focusing on identity systems that are often under-monitored by traditional tools.
| Role of Traditional Tools | Role of ITDR |
| IAM manages and controls user access. | ITDR adds real-time threat detection and response to IAM policies. |
| SIEMs aggregate and analyze logs. | ITDR can feed identity-related events into SIEM for correlation. |
| EDR focuses on endpoint threats | ITDR monitors identity abuse that may originate or propagate via endpoints. |
| XDR correlates data across multiple security layers. | ITDR strengthens the identity signal in XDR platforms. |
How ITDR Fits into a Zero Trust Strategy
Zero Trust principles dictate that no user or device is trusted by default, even inside the corporate network. ITDR reinforces this model by:
- Validating identity behavior continuously, not just at the point of login
- Detecting trust violations, such as lateral movement or abnormal privilege usage
- Supporting micro-segmentation and least privilege enforcement by identifying over-privileged accounts
- Enabling dynamic response to threats (for example, quarantine or re-authentication triggers)
In essence, ITDR operationalizes Zero Trust for identity systems, providing both visibility and control.
How ITDR Works
ITDR-relevant attacks often begin with tactics like phishing, credential theft or exploitation of misconfigured identity systems. Once attackers gain access, they may escalate their privileges, move laterally using legitimate credentials and target identity infrastructure (such as Active Directory) to maintain persistence. These identity-based attacks are stealthy, often blending in with normal user behavior — making dedicated ITDR tools essential for early detection and response.
Stages of ITDR
ITDR involves the following four key elements:
- Detect — ITDR solutions continuously monitor identity systems in real time for suspicious behavior, such as unusual access attempts or abnormal usage patterns.
- Analyze — When a potential threat is detected, the system evaluates contextual identity signals (such as time, location, device and access patterns) to determine severity and legitimacy.
- Respond — Based on the threat level, ITDR can trigger automated responses, such as forcing reauthentication, revoking tokens, disabling accounts or alerting security teams.
- Improve — Post-incident, ITDR tools feed findings back into the system to refine detection models and strengthen future responses, contributing to continuous security posture improvement.
Real-Time Monitoring and Behavioral Analytics
At the heart of ITDR is real-time monitoring of identity infrastructure. This includes tracking user login behavior, privilege changes, lateral movements and unusual access to resources. ITDR establishes baselines of normal user behavior and flags deviations that may indicate compromise or insider threats. This capability allows ITDR to identify subtle and sophisticated attacks that static rule-based systems might miss.
AI and Machine Learning in Identity Signal Processing
Modern ITDR tools employ artificial intelligence (AI) and machine learning (ML) algorithms to process vast volumes of identity-related data. These technologies enable the system to:
- Detect patterns and anomalies that suggest malicious intent
- Predict potential compromise paths based on user behavior trends
- Continuously refine detection capabilities using feedback loops
By automating threat correlation and risk scoring, AI enhances the speed and accuracy of threat detection, significantly reduce response time, and help security teams prioritize actions more effectively.
Key Components of an ITDR Strategy
An effective ITDR strategy relies on several integrated components that enhance visibility, detection accuracy and response efficiency across identity systems in hybrid and cloud environments:
- Threat intelligence — ITDR solutions ingest external threat intelligence feeds and correlate them with internal identity data to detect known indicators of compromise (IOCs). Aligning currently observed behaviors with established threat actor patterns enables faster identification of tactics like credential stuffing, password spraying and use of stolen tokens.
- User and entity behavior analytics (UEBA) — UEBA establishes baselines for normal user and system login times, access locations, resource usage and so on. Any deviation from these baselines, like an access request from an unusual IP or attempts to modify data in an unusual way, merits further analysis and may trigger a response action, such as an MFA challenge or security team alert. This behavior-based approach helps detect stealthy insider attacks and advanced persistent threats (APTs), which traditional rule-based systems may miss.
- Adaptive access policies — An advanced ITDR strategy includes adaptive, risk-based access controls. These policies dynamically adjust authentication requirements based on real-time risk assessments. For instance, a login attempt from a new device in a high-risk region may trigger additional verification steps or temporary access restrictions.
- Integration with SOC and other security tools — For seamless incident response, ITDR must integrate with the Security Operations Center (SOC) and tools like SIEM, EDR and XDR platforms. This ensures identity-related alerts are part of the broader security ecosystem, enabling faster triage, automated playbooks and coordinated defense against multi-vector attacks.
Identity-Based Threats Addressed by ITDR
ITDR solutions can address a wide range of identity-based threats, including the following.
Credential Theft (Account Takeover)
Attackers steal usernames and passwords through methods such as brute-force attacks, credential stuffing and data breaches. They then use those legitimate credentials to enter the network and advance their attacks while avoiding detection.
How ITDR Helps
- Detects abnormal login behavior, such as impossible travel or use of a new device
- Flags the use of stolen or leaked credentials via integration with threat intelligence feeds
- Monitors for suspicious access patterns that deviate from normal user behavior
Session Hijacking
By hijacking active sessions using stolen tokens or session IDs, adversaries can bypass authentication mechanisms.
How ITDR Helps
- Monitors for irregular session behavior, like session reuse or geographic anomalies
- Detects simultaneous session activity from multiple IPs or locations
- Employs session fingerprints and behavioral baselines to identify hijacked sessions
Insider Misuse and Privilege Escalation
Malicious insiders or compromised accounts attempt to access or manipulate resources beyond their intended scope, often by escalating privileges.
How ITDR Helps
- Flags attempts to access sensitive systems or data outside of regular responsibilities
- Detects unauthorized privilege elevation or lateral movement in identity systems
- Integrates with privileged access management (PAM) tools to monitor and control the actions of accounts with elevated permissions
Phishing and Social Engineering
Attackers deceive users into revealing sensitive information (such as login credentials and MFA codes) via emails, text messages or fake login portals.
How ITDR Helps
- Analyzes anomalies post-authentication, such as unusual MFA usage or login patterns
- Identifies successful phishing attempts through behavior deviations
- Integrates with email security and SIEM tools to correlate phishing campaigns with identity threats
Identity Infrastructure Exploitation
Attackers exploit misconfigurations or vulnerabilities in identity systems like Active Directory, Entra ID or identity providers.
How ITDR Helps
- Monitors for anomalous changes to identity infrastructure, such as the creation of new trust relationships or service accounts
- Alerts on high-risk configurations, unauthorized schema modifications and disabled security settings
- Detects signs of domain dominance, Golden Ticket attacks and other advanced tactics
Building an Effective ITDR Program
Building a successful ITDR program requires:
- Clear visibility and control across identity systems
- Environment-specific threat awareness to close configuration and visibility gaps
- Integrated automation and orchestration to enable fast and scalable responses
Assess Your Identity Security Maturity
To begin building a robust ITDR strategy, organizations must evaluate their current identity security posture.
| Practice | Description |
| Understand your identity environment. | Conduct an inventory of all identity systems, such as Active Directory, Entra ID, Okta and IAM tools.Identify all identity types, both human (employees, contractors) and non-human (service accounts, APIs). |
| Evaluate existing controls. | Check coverage of MFA, single sign-on (SSO), PAM and identity governance.Assess logging and monitoring capabilities for identity systems.Review incident response readiness for identity-based attacks. |
| Assess the maturity of your current setup. | Use a maturity model to determine your starting state: Initial — Manual identity management, limited visibilityDeveloping — Partial monitoring, basic identity hygieneDefined — Centralized IAM, identity policies in placeManaged — Continuous monitoring, SIEM/SOAR integrationOptimized — Proactive threat hunting, adaptive risk-based access control |
Identify Gaps Across Environments
Next, look for gaps in your various IT environments:
| Environment | Potential Gaps |
| On-premises | Lack of visibility into legacy systems like Active DirectoryLimited detection of attacks like Kerberoasting, Pass-the-Hash and Golden Ticket Misconfigured GPOs Infrequent auditing |
| Hybrid | Inconsistent security policies between cloud and on-premLimited correlation of identity activity across environmentsChallenges in enforcing conditional access policies |
| Multi-cloud | Identity sprawl across environmentsSiloed identity data and policiesMisconfigured federationLack of unified visibility into access behavior |
Address the issues you find. Mitigation tactics could include:
- Implement centralized identity governance.
- Normalize and correlate identity telemetry from all platforms.
- Rigorously enforce the least privilege principle.
Importance of Security Orchestration and Automation (SOAR)
ITDR’s effectiveness hinges on rapid detection and response, which is feasible only through security orchestration and automation. SOAR integration:
- Automates triage of identity threats using playbooks
- Coordinates responses across SIEM, EDR, IAM, and ticketing systems
- Reduces alert fatigue through correlation and prioritization
- Automates response actions to threats, such as locking accounts or triggering an MFA challenge
- Enables adaptive access control based on risk level (device, location, behavior)

Real-World Applications and Use Cases
Here’s an in-depth look at real-world applications of ITDR, illustrating how it functions in live environments to detect, mitigate and respond to identity-based threats.
Incident Detection
Lateral Movement Detection
| Use case | An attacker gains access to a low-privileged user account and begins moving laterally within the network to escalate privileges and reach critical assets. |
| How ITDR helps | Monitors for abnormal authentication patterns between systemsFlags unusual access to high-value targets, such as domain controllers, finance systemsDetects tools commonly used in lateral movement, such as PsExec |
| Example scenario | An attacker compromises a contractor account and then uses those valid credentials to RDP into a series of machines, eventually accessing an executive’s system. ITDR triggers alerts based on anomalous behavior and identity access paths. |
Credential Misuse and Abuse
| Use case | Stolen or misused credentials are used to access systems at odd hours or from untrusted locations. |
| How ITDR helps | Correlates login metadata: time, device, location, behaviorIdentifies anomalous logins based on the user’s historical patternsIntegrates with threat intelligence to detect logins from known malicious IPs |
| Example scenario | A user’s credentials are phished and used in a midnight login from an offshore IP. ITDR detects “impossible travel” and tags it as high-risk behavior, triggering response workflows such as account lockout. |
Adaptive Controls and Automated Response
Auto-Locking High-Risk Accounts
| Use case | ITDR detects risky behavior that signals compromise, such as sudden privilege escalation or use of dormant admin accounts. |
| How ITDR helps | Automatically disables or locks affected user accountsSends alerts and initiates password reset workflowsOptionally requires identity re-verification via MFA or identity proofing |
| Example scenario | An inactive account suddenly attempts to access a privileged system. ITDR automatically locks the account and notifies the SOC team, preventing further access while triage is conducted. |
Conditional Access Enforcement
| Use case | Implement context-aware access decisions based on real-time risk evaluation. |
| How ITDR helps | Requires step-up authentication (for example, MFA challenge) when identity risk score is highAdjusts access rights dynamically based on the user’s behavior, device posture or locationWorks with IAM platforms to block, restrict or allow access |
| Example scenario | An employee attempts to access sensitive HR data from a personal device on a public network. ITDR evaluates the risk and enforces a policy that denies access until the user switches to a corporate VPN. |
ITDR vs. Other Cybersecurity Acronyms
ITDR vs. EDR
While endpoint detection and response focuses on the device, ITDR zeroes in on the identity, detecting threats that bypass endpoint defenses, especially in cloud or SaaS-heavy environments.
| Feature | ITDR | EDR |
| Focus | Identity-based threats (such as account takeover, privilege abuse) | Endpoint-based threats (such as malware, exploit activity) |
| Scope | Identity infrastructure (Active Directory, Entra ID, IAM) | Endpoints (laptops, servers, mobile devices) |
| Detection | Abnormal access, credential misuse, lateral movement via identities | Malicious binaries, process injection, fileless malware |
| Response | Account locking, privilege revocation, session termination | Process kill, endpoint isolation, forensic capture |
ITDR vs. XDR
Extended detection and response provides a holistic security view, and ITDR can feed identity-centric telemetry into an XDR system. However, XDR platforms without strong ITDR capabilities may miss identity-layer blind spots, especially in lateral movement or post-auth compromise.
| Feature | ITDR | XDR |
| Focus | Identity-specific activity and threats | Cross-layer correlation: endpoint, network, cloud, email, and identity |
| Scope | Limited to identity systems | Expansive: integrates EDR, NDR, email security and more |
| Detection | Detects anomalies in authentication patterns, privilege escalation, credential misuse | Correlates telemetry from multiple sources to detect complex, multi-vector attacks |
| Response | Focused on identity-related incidents (e.g., disabling compromised accounts, revoking access) | Centralized incident response across different security domains |
| Strength | Deep identity analytics and risk scoring | Broad telemetry aggregation and incident correlation |
ITDR vs. MDR
Managed detection and response (MDR) can include ITDR, meaning it is included as a component to cover identity-related threats.
| Feature | ITDR | MDR |
| Nature | Technology or solution | Service that provides 24/7 monitoring and incident response |
| Detection domain | Identity threats | Varies: endpoint, network, cloud and identity |
| Management | Usually in-house or integrated with IAM or SIEM | Delivered by an external security team |
Why ITDR Is Not Just Another Buzzword
- ITDR fills a real gap. Modern attacks almost always involve identity compromise. According to Microsoft, 98% of cyberattacks involve identity compromise at some stage of the kill chain. Traditional EDR and SIEM tools often miss these indicators, especially if no malware is involved.
- It is purpose-built for identity systems. ITDR solutions are designed to monitor identity systems such as Active Directory, Entra ID, Okta and IAM platforms. They detect subtle forms of identity abuse, including Golden Ticket attacks, credential stuffing, misuse of dormant accounts and violations of conditional access policies. Additionally, ITDR tools integrate natively with IAM, SIEM and SOAR platforms to enable adaptive, automated responses.
- It is critical in Zero Trust and cloud-first strategies. In a Zero Trust world, identity is the new perimeter and every access request is a potential threat vector. ITDR ensures that identity activity is continuously verified and monitored — which is especially vital in hybrid and multi-cloud environments.
- It is recognized by industry leaders. Gartner and Forrester recognize ITDR as a core component of identity fabric architectures, with emphasis on ITDR as a must-have capability in modern security stacks. Moreover, ITDR is considered critical for achieving compliance in highly regulated sectors such as finance and healthcare.
Future of Identity Threat Detection
Emerging Trends
Decentralized Identity (DID)
Decentralized identity models, in which individuals control their identity credentials without relying on centralized providers, are gaining traction. To keep up, future ITDR tools will:
- Monitor and validate decentralized identifiers and verifiable credentials.
- Detect anomalies in decentralized authentication workflows.
- Integrate with blockchain-based identity systems and self-sovereign identity (SSI) frameworks.
Machine and Non-Human Identities
APIs, IoT and non-human identities are proliferating across environments, which will necessitate the following changes:
- ITDR will expand to monitor machine identities, service accounts, containers, bots and workload identities.
- Behavior-based baselining will be applied to non-human identity activity.
- Protection will expand to include certificate rotation, secret misuse detection and API abuse prevention.
DevOps and Developer Environment Security
Identity risks are becoming more pronounced in DevOps pipelines, with attackers targeting CI/CD systems, developer credentials and build tools. We can expect the following response:
- ITDR will be extended to monitor access to developer tools like GitHub, Jenkins and Terraform.
- Identity risk signals will be embedded into DevSecOps workflows to enable secure-by-design engineering.
Predictions for ITDR’s Role in Enterprise Cybersecurity
- Core pillar of Zero Trust architectures — As enterprises implement Zero Trust, ITDR will serve as a real-time enforcement layer, continuously evaluating identity risk and dynamically adjusting access. Identity will no longer be a static gatekeeper but a context-aware signal across every access decision.
- Deep integration with cyber mesh and unified security platforms — ITDR will integrate into broader cybersecurity mesh architectures, feeding identity telemetry into SIEM, SOAR and XDR platforms. Expect native support across ecosystems like Microsoft Entra, Google BeyondCorp and Okta Identity Engine.
- AI-driven identity analytics — Artificial intelligence and machine learning will drive predictive identity threat detection, enabling detection of unknown attack patterns, early warning of identity anomalies before compromise, and automated risk scoring and policy tuning based on behavioral intelligence.
- Regulatory and compliance catalyst — As data privacy regulations expand, ITDR will play a vital role in proving access control integrity, auditing privileged identity use, and supporting compliance with standards like HIPAA, PCI DSS and GDPR.
Conclusion: Why ITDR Matters

FAQs
What does ITDR mean?
ITDR stands for “identity threat detection and response”.
What is ITDR in cybersecurity?
A good ITDR definition is as follows: a set of tools and processes designed to detect, investigate and respond to identity-based threats. Examples of identity-based threats include logon requests from unusual locations and attempts to download significant amounts of data.
What is the difference between ITDR and XDR?
ITDR and XDR are both cybersecurity solutions focused on threat detection and response, but they differ in scope and specialization:
- ITDR is focused on enhancing security around user identities and access.
- XDR helps organizations detect and respond to threats across the entire IT environment.
They are complementary, not mutually exclusive — organizations can benefit from using both together.
See the section “ITDR vs. XDR” for additional information.
What is the difference between ITDR and UEBA?
ITDR and UEBA are complementary security technologies. Both focus on user-related threats, but they differ in the following ways:
| ITDR | UEBA | |
| Focus | Detecting and responding to identity-based threats | Analyzing user behavior to detect anomalies |
| Functionality | Monitors identity systems and access patterns to detect suspicious activity like credential abuse, privilege escalation and identity misuse | Uses machine learning and analytics to create baselines of normal user behavior and detect deviations that may indicate insider threats or compromised accounts |
| Scope | Broader, action-oriented: includes detection, investigation, and response tailored to identity systems | Analytical: focuses on behavioral patterns and insights, often used as an input into larger detection systems |
| Threat types addressed | Credential theft, privilege abuse, identity-based lateral movement | Insider threats, data exfiltration, abnormal access behavior |
| Integration | Often integrates with IAM, Active Directory and SSO systems | Integrates with SIEMs, DLPs and other analytics platforms |
Is ITDR the same as IAM?
No, ITDR is not the same as identity and access management. They work best when integrated — IAM provides control while ITDR adds visibility and security intelligence to that control. Here is a summary of their different but complementary purposes in cybersecurity:
| ITDR | IAM | |
| Purpose | Detection and response to identity-related threats | Identity management, authentication and authorization |
| Functionality | Identifies threats like suspicious login activity, privilege escalation and credential misuse | Grants/revokes access, enforces least privilege, manages roles and policies |
| Tools | Integrates with IAM, Active Directory, SSO, etc., for real-time threat detection and response | Solutions like Okta, Microsoft Entra ID, Ping Identity for access provisioning and control |
How is ITDR implemented in hybrid cloud environments?
Implementing ITDR in hybrid cloud environments involves integrating identity security tools and threat detection capabilities across both on-premises and cloud infrastructures. Here are the key steps involved:
- Integrate with identity providers. ITDR solutions connect to identity systems such as Active Directory and Entra ID to enable visibility into authentication patterns and access behaviors across all environments.
- Centralize identity telemetry. Gather and normalize identity-related data (logins, failed access attempts, etc.) from cloud and on-prem systems into a centralized platform or SIEM for unified monitoring and threat correlation.
- Enable continuous monitoring. Use ITDR tools to continuously analyze user behavior across the hybrid environment. Machine learning and behavior analytics help identify threats like unusual access times, location shifts or privilege abuse.
- Automate threat detection and response. Deploy automated detection rules and response playbooks to defend against identity threats by locking compromised accounts, requiring MFA, alerting security teams for manual investigation, and so on.
- Ensure policy consistency. Align access controls, authentication standards, and related policies across cloud and on-prem environments to avoid identity gaps and reduce the attack surface.
- Integrate with the broader security stack. ITDR should work with other security tools (XDR, SIEM, SOAR) to enhance correlation, investigation, and incident response across hybrid environments.
Who needs ITDR and why?
Organizations of all sizes and across all sectors need ITDR to protect against identity-based threats. As cyberattacks increasingly target user credentials and access points, ITDR helps detect suspicious identity activity and enable quick response to threats in progress.
