What is ITDR? A Definition for 2025 and Beyond
Identity Threat Detection and Response (ITDR) is a cybersecurity practice that focuses on protecting digital identities - users, credentials, and entitlements - by detecting suspicious behavior, flagging misuse, and enabling fast response to identity-based threats.
Where traditional security tools focus on endpoints or networks, ITDR zeros in on the who, what, and where behind identity activity across your organization. It monitors how accounts and users behave, identifies anomalies based on context and risk, and surfaces threats like lateral movement, privilege escalation, and unauthorized access - especially within cloud and SaaS platforms.
At its core, ITDR answers a critical question: Are the right identities doing the right things, at the right time, for the right reasons?
Modern ITDR platforms integrate identity behavior analytics, access context, and adaptive risk scoring to surface threats that might otherwise go unnoticed. They don’t just detect; they enable security teams to respond - whether that means revoking access, remediating permissions, enforcing step-up authentication, or alerting security or SOC teams for deeper investigation.
As more organizations embrace remote workforces and decentralized SaaS environments, ITDR is becoming a strategic imperative.
ITDR Security: Key Concepts
There are a plethora of identity-centered threats facing companies today. Here are the ones you’re most likely to encounter:
Phishing
- Phishing attacks see cybercriminals use legitimate-looking, convincing messages that trick users into revealing their login credentials.
- These communications could appear to have originated from one of your service or solutions providers, or even from within your company itself.
- Bad actors often use persuasive branding, logos, and other imagery to fool users into believing that what they’re seeing is the real thing.
Social Engineering
- In these sophisticated identity-focused attacks, cybercriminals impersonate a real individual, oftentimes someone that the victim actually knows.
- This could be a senior-level executive at your organization, a trusted colleague, or even a client.
- Once the target is convinced they are communicating with a legitimate person, they may turn over sensitive data, credentials, or other information to the cybercriminal.
Identity Theft
- Aimed at obtaining users’ personal information and login credentials, these attacks can manifest in many different ways.
- Oftentimes, bad actors leverage login info, such as usernames and passwords, that were leaked in previous data breaches.
- Using these credentials, cybercriminals infiltrate organizations while pretending to be a specific employee and using their access to obtain sensitive data for nefarious reasons.
Insider Threats: A Brief Look
Insider threats are a crucial part of understanding ITDR. While we won't dive too deep into them here, you can learn about different type of identity based threats here.
The Three Faces of Insider Threats
Not all insider threats are created equal. In fact, one of the biggest challenges in detecting them is that they don’t follow a single pattern. The motivations and behaviors behind insider risk can vary, but most fall into three key categories:
- Malicious insiders – These are users with intent to harm. They might steal data, sabotage systems, or leak sensitive information for financial or competitive gain. Think of a disgruntled employee that was terminated, and wants to sell proprietary code or roadmaps to a competitor.
- Negligent insiders – Often well-intentioned, these users accidentally expose data through carelessness. Think of a regular, hard-working employee at your organization. They are just trying to do their job, but don’t know the security risks behind miniscule & seemingly harmless actions they take. For example, instead of sharing an asset directly with a user, they set it to 'Public,' meaning anyone with the link can access it. We see this time and time again with extremely sensitive information such as salaries, budget files, and more.
- Compromised insiders – These company accounts have been hijacked by external actors. Think of a stereotypical evil hacker from a movie that is trying to do some serious damage. These threats often manifest via phishing, credential stuffing, or stolen OAuth tokens. Though the activity comes from a trusted account that looks legit (since it’s probably a domain from your company in most cases), the user behind it is not who you think it is.
Each of these types represents a serious risk – but it’s the blending of categories that makes detection especially tricky. A careless employee might fall victim to a phishing email, turning a negligent insider into a compromised one overnight. In SaaS environments, where access is fluid and often over-provisioned, that shift can go undetected for weeks.
Why is ITDR a 2025 Priority?
ITDR isn’t just a buzzword, it’s rapidly becoming a recognized category within enterprise security strategy. Analysts and CISOs alike are sounding the alarm on identity threats, and the market is responding accordingly.
Gartner’s recent insights highlight the growing importance of IDTR in 2025 security budgets.
Gartner recently presented their take on top cybersecurity budget priorities for 2025, where they listed Identity Threat Detection and Response (ITDR) as a critical priority.
This surge in adoption reflects a larger industry trend. Identity has become a key control point in Zero Trust architectures, and security leaders are re-evaluating how to protect it. SaaS platforms are enhancing their APIs to support third-party ITDR integrations. And, CISOs are being held accountable for identity attack surface management now more than ever.
In short: the momentum behind ITDR isn’t just vendor-driven - it’s being pulled forward by operational necessity and large scale market shifts.
How Modern ITDR Solutions Are Built for SaaS
To be effective in today’s SaaS-first world, ITDR tools must do more than monitor login logs or set blanket access policies. They need to be SaaS-native, deeply contextual, and responsive to real-time identity behavior.
Modern ITDR platforms offer:
- Continuous monitoring of identity behavior across multiple SaaS environments
- Contextual detection based on roles, typical access patterns, and risk posture
Dynamic risk scoring that surfaces identities most likely to be compromised or misused - Automated response capabilities - like session revocation or privilege reduction - when risky activity is detected
DoControl’s approach to ITDR reflects these needs. We’ve embedded identity detection and response as a core layer within our SaaS security platform, not as a bolt-on, but as a foundational feature. Our platform ingests and analyzes identity activity across major SaaS apps, scoring risk based on real-world behavior, privilege levels, and environment-specific context.
The result? Security teams gain clarity on which identities pose risk, why they’re risky, and what can be done about it - before a threat turns into an incident.
The Fundamentals of Effective ITDR Security
Let’s break down the basic components of a strong ITDR strategy to protect your business.
Identity Management
- Identity management plays a critical role within ITDR, because it helps prevent breaches before they occur and means that you stay on top of unusual activity.
- Authentication and authorization mechanisms such as multi-factor authentication (MFA) and verification emails are important tools to help ensure that logins are legitimate, as part of a zero-trust approach that ensures credentials aren’t enough to gain access.
- This could look like sending an SMS or other notification to a user’s physical device and requiring them to enter a confirmation code. This way, even if their credentials were stolen, a bad actor can’t log in.
Monitoring Systems
- You should leverage tools and platforms for monitoring identity-related activity and user behavior. These solutions can continuously review login attempts and access controls, informing you when something is out of the ordinary.
- Log analysis and correlation techniques help you quickly recognize strange user behavior, which may be indicative of a bad actor trying to gain access to your organization’s systems and data.
- Consider setting notifications for unusual events, so you can act fast if something is amiss.
Incident Response Tools
- These technologies help you respond to identity threats in real-time, meaning that you can stop a potential breach while it’s in progress.
- Look for tools that offer automation and orchestration capabilities, so that a series of measures are automatically rolled out should a suspicious event occur (e.g. a login attempt from a foreign country automatically triggers an alert and a verification SMS).
- You can usually implement custom settings within these tools, such as tiered prioritization of emerging threats and automated protocols for specific scenarios.
Best Practices for ITDR Security
These best practices can help you ensure an effective ITDR strategy to safeguard your organization.
Proactive Measures
Education and training for employees can be extremely effective in protecting your company from identity-focused attacks. Implementing security awareness programs that teach your teams about classic warning signs of phishing and other attacks are critical for raising awareness.
Continuous Improvement
Conducting regular security assessments and audits is crucial. Integration with threat intelligence feeds can help you stay on top of the latest ITDR risks and ensure you’re aware of emerging threats. Being complacent could mean setting your organization up for disaster.
Collaboration and Communication
Coordination among IT, security, and business teams is key to ensuring the overall cybersecurity of your business, including ITDR. Incident reporting and communication protocols should be laid out clearly, and you should work to take down any information silos: all teams should be forthcoming and honest about any concerns.
ITDR Challenges and Considerations
Scalability may be a challenge for ITDR solutions. For large organizations with hundreds or thousands of employees, this is particularly complex. Adopting a zero-trust approach alongside tools that can grow with your business is paramount. Consider creating a dedicated SOC team that specifically deals with alerts regarding identity threats.
Compliance and Privacy
There are a number of legal requirements related to identity protection, especially in highly regulated industries such as healthcare and finance. You’ll need to ensure that your ITDR tools are in compliance with data protection laws.
Privacy concerns are also a factor. Balancing security needs with privacy considerations may complicate your use of specific monitoring solutions. These tools will also need to safeguard personal information during incident responses.
ITDR Future Trends
AI and Machine Learning are continuing to improve identity threat detection and response solutions. As new threats begin to crop up, these solutions should be able to recognize additional ITDR risks as they occur.
The increasing popularity of blockchain may yet make an impact on ITDR. With blockchain for identity management emerging as an appealing option, this may become a more mainstream choice within an overall identity protection strategy.
Here’s What Your ITDR Solution Should Provide
There are a number of solutions aimed at detecting and resolving ITDR risks, both stand-alone and those within overall SaaS tools. However, these solutions aren’t all created equal and may not provide what you need for effective ITDR security.
Your ITDR solution should include the following:
Smart Identity Security Posture Discovery
Ever hear of alert fatigue? This term is used to describe solutions without the ability to distinguish between normal business activity and behavior that should raise a red flag.
Oftentimes, these tools end up bombarding security teams with so many notifications about potential threats that teams simply stop paying attention.
Even worse, this means that actual pressing security issues end up getting lost in the mix, and may never be mitigated.
Your ITDR solution should use aggregated data visibility for true risk prioritization. That means each identity within your business should be risk-assessed, based on comprehensive data collection including data access patterns, user permissions and relevant business context from HRIS.
Whether it’s in reference to a long-time employee or third-party contractor, your ITDR solution should be able to determine high-risk scenarios and users and flag them, notifying you about the threats that really matter.
Advanced User Behavior Anomaly Detection
Your ITDR solution needs to monitor activity anomalies based on user and department benchmarks. That means it should be able to establish a baseline of normal behavior, so that sudden changes from that standard become a cause for concern and action.
A strong ITDR solution must alert security teams regarding deviations from normal identity activity patterns. For example, this could look like when a finance employee shares an unusual number of files with an external account.
The same goes for other unusual behaviors that could be a sign of something nefarious. Without an understanding of what’s normal and what’s a potential risk, your solution can’t detect or notify you in the event of suspicious activity.
Robust User-level Response
With the average businesses granting hundreds or even thousands of access permissions to individual users, managing all your exposures across many user identities and resources is more challenging than ever before.
Whether you want to remove access for an employee who’s recently departed from your company or a third-party collaborator, manual management of access controls is timestaking and oftentimes simply not effective in today’s reality.
You need a system that both enables you to perform bulk and automated removals, along with the option to remove exposure per user and manage data access across identities.
Your ITDR solution should enable on-demand permission changes per user across SaaS applications and assets, as well as internal and third-party user suspension or deactivation.
