What is ITDR?

Identity Threat Detection and Response is a cybersecurity approach focused on protecting digital identities—such as users, service accounts, and machine identities—from compromise, misuse, and abuse. As identities have become the primary control plane in cloud, SaaS, and hybrid environments, attackers increasingly target them instead of traditional infrastructure. ITDR is designed to detect, investigate, and respond to those identity-based threats.

ITDR continuously monitors identity-related activity to identify suspicious or malicious behavior, including:

  • Stolen or compromised credentials
  • Privilege escalation and abuse
  • Lateral movement using valid accounts
  • Persistence techniques hidden in identity systems
  • Misconfigurations in identity platforms (e.g., excessive privileges)

ITDR By Adlumin AI Security (Dedicated Identity Security Service)

ITDR is designed to monitor, detect, and respond to suspicious activity tied to user accounts—like stolen credentials, account takeovers, or unusual login behavior before it turns into a breach.   San Diego Computer Consulting sells Adlumin as an ITDR security service to protect our clients from identify theft and breaches through Microsoft login.

Adlumin’s ITDR solution integrates directly with platforms like Microsoft 365 and continuously analyzes identity activity. It:

  • Collects identity data (logins, access attempts, behavior patterns)
  • Builds a baseline of what “normal” looks like for each user
  • Detects anomalies (e.g., impossible travel, unusual login times, privilege escalation)
  • Responds automatically or alerts analysts when something suspicious happens

Adlumin for Microsoft Office 365 Email, SharePoint, and Applications

Adlumin’s Identity Threat Detection and Response service enhances Microsoft 365 Office 365 security by continuously monitoring user identities, login activity, and behavior across services like Azure AD (Entra ID), Exchange Online, OneDrive, and Teams. It analyzes this data to establish a baseline of normal user behavior and quickly detects anomalies such as unusual logins, impossible travel, privilege escalation, or signs of compromised accounts.

When suspicious activity is identified, Adlumin can automatically respond by disabling accounts, forcing password resets, or alerting security teams, helping stop threats before they spread. By adding behavioral analytics, real-time detection, and optional 24/7 SOC support, Adlumin fills critical gaps in native Microsoft 365 security, providing a more proactive and comprehensive defense against identity-based attacks.
