Identity Assurance and Threat Detection (IATD)

Identity Assurance and Threat Detection (IATD) is a security approach that combines identity verification, adaptive authentication, and real-time cybersecurity threat detection and support to help organizations secure access to critical systems and sensitive data. Rather than relying solely on static credentials, IATD evaluates identity risk using contextual signals, such as login behavior, device posture, credential reputation, and geographic anomalies. This enables organizations to prevent unauthorized access and identify suspicious activity in real time as remote work, cloud adoption, and third-party access continue to expand.

At its core, IATD uses dynamic identity assurance levels that adjust authentication requirements based on contextual risk. Instead of treating every login request equally, the system evaluates factors such as device posture, behavioral anomalies, authentication history, and geographic location to determine the appropriate level of trust. When elevated risk is detected, organizations can require additional verification steps, restrict privileges, or block access entirely to stop unauthorized access and strengthen cybersecurity threat response.

These identity assurance levels help align security controls with the sensitivity of the systems and data being accessed. Identity Assurance Level 1 (IAL1) is generally used for lower-risk access scenarios with minimal identity proofing requirements. Identity Assurance Level 2 (IAL2) introduces stronger identity verification and multifactor authentication (MFA) requirements for environments containing sensitive business or customer information. Identity Assurance Level 3 (IAL3) provides the highest level of assurance through rigorous identity proofing and stronger authentication controls for highly regulated, mission-critical, or high-risk systems.

IATD also improves operational visibility by helping organizations view all active accounts and monitor how identities interact with systems, applications, and privileged resources. Security teams can detect abnormal activity involving employees, contractors, and third-party vendors while applying flexible authentication policies across different user groups. Expanded authentication methods, including biometric MFA, strengthen identity verification and help organizations prevent cybersecurity attacks that target privileged accounts and compromised credentials.

Within privileged access environments, IATD extends traditional privileged access management controls by incorporating real-time identity risk analysis into authentication and access workflows. This allows organizations to respond more effectively to emerging threats, strengthen privileged access decisions, and reduce the risk of unauthorized lateral movement within the environment.

Imprivata Customer Privileged Access Management (CPAM) incorporates Identity Threat Detection and Response (ITDR) capabilities through risk-based authentication workflows, adaptive authentication, biometric MFA options, and contextual access controls. These capabilities help organizations strengthen cybersecurity threat response across both internal users and external vendors while improving visibility into identity-related risk. By combining privileged access management with continuous identity assurance, Imprivata helps organizations prevent unauthorized access and secure privileged accounts without introducing unnecessary operational complexity.
