EDR, MDR, XDR…oh my. The number of acronyms in the cybersecurity industry could make for a nicely seasoned alphabet soup. The last thing we need is another one, right? Wrong! As I read once in a Reddit thread: “An acronym a day keeps hackers away.” Yes, poster, well put.��

Call it a security solution, a product category, a cybersecurity approach, or an analyst buzzphrase—identity threat detection and response (ITDR) is the latest acronym you can’t escape. And you won’t want to.��

First introduced by and later featured in its , ITDR was developed “to describe the collection of tools and best practices to defend identity systems.” Since then, digital identities have become even more ubiquitous in our everyday lives. The ITDR market, , has appropriately followed suit. Today, ITDR as a cybersecurity category has evolved to more broadly describe solutions focused on protecting identities and credentials and responding to identity-related attacks.��

But, WTF (..and that’s frick, folks. Get your mind out of the gutter) is ITDR? Imagine a watchtower constantly scanning for unauthorized access, misuse of credentials, and any sneaky behavior that could put your business at risk. ITDR doesn’t just monitor—it identifies threats in real-time and takes swift action to neutralize them.

Think of it this way: while traditional security solutions focus on keeping the bad guys out, ITDR ensures that even if they manage to sneak in, they don’t get far. It’s about protecting what matters most—your people, their access, and, ultimately, your bottom line.

Why ITDR Matters

As businesses continue to move to the cloud, they’re juggling a complicated mix of on-prem infrastructure, cloud apps, and remote workspaces, creating a tangled web of interconnected systems. The result? A bigger attack surface and more entry points for bad actors. According to the , stolen credentials—a common identity vector—have appeared in almost one-third (31%) of breaches over the past 10 years. The �Ӱɴ�ý Security Operations Center (SOC) alone detects more than 2,000 suspected credential attacks every week.

All it takes is one set of valid employee credentials for an attacker to waltz into your business, snoop around, escalate their access, and cause havoc. Whether they're locking you out, shutting down services, wiping out data, or nuking resources—it’s game over.��

How ITDR Works

ITDR involves monitoring, identifying, and mitigating threats related to unauthorized access and misuse of identity credentials within an organization. This includes using both human and technological measures to detect anomalies and respond effectively to potential security incidents, ensuring the protection and integrity of identity systems and data.

While there can be different flavors of ITDR (pre-compromise vs. post-compromise), ITDR solutions usually have the following key aspects:

• Proactive Identity Protection: Aggressive pre-compromise capabilities to reduce threats and fix vulnerabilities before attackers get a chance to strike.
• Real-Time Threat Detection: Immediate identification and alerting of suspicious or malicious activities as they occur.
• Monitoring of Attack Techniques: Coverage of adversary tactics and techniques throughout the attacker kill chain.��
• Automated and Customizable Incident Response: Automatic application of controls to isolate and stop identity attacks.�� 

Who Needs ITDR?

In short, everyone.

No organization is safe from identity-based attacks. With attack surfaces spread across multiple locations, accounts, and devices, all it takes is one person, one compromised credential, or one weak app for hackers to bust through the doors and wreak havoc on your entire digital infrastructure.

That’s why ITDR has become a must-have in any solid cybersecurity game plan for all organizations—regardless of size or industry. Because identities have become the primary targets of attackers looking to gain unauthorized access to sensitive systems and information, organizations can employ an ITDR solution to protect themselves from identity-related threat vectors like session hijacking, credential theft, account takeover, and business email compromise (BEC).��

Choosing the Right ITDR Solution

ITDR solutions come in many flavors—and finding the right flavor depends largely on the security maturity of your organization. Some factors to consider:

• Where are your organization’s identity threats most likely to occur (on-prem, cloud, remote workforce)?
• Do you have the in-house resources and security expertise to maintain an ITDR solution or would you be better off with a managed solution? 
• Are you a managed service provider (MSP) or a small business? How scalable is the solution as your organization grows? 
• Does the solution offer real-time detection and automated response capabilities? Are human experts involved?
• How does the solution integrate with your existing systems (EDR, IAM, SIEM, etc.)?

�Ӱɴ�ý and ITDR 

Wait, �Ӱɴ�ý has an ITDR solution? Heck yeah, we do! What you might’ve known as MDR for Microsoft 365 just got a major upgrade and a new name—�Ӱɴ�ý Managed ITDR. We’ve added Unwanted Access, a slick new capability that helps you outsmart hackers by shutting down their go-to moves like session hijacking and credential theft. Oh, and by the way, we’ve crossed the milestone of protecting over a million identities (and we’re just getting started).

Our new ITDR category isn’t just a shiny label—it’s a clearer reflection of where we are and where we’re heading. Stay tuned, because there’s a lot more to come. 🚀
