IDENTITY THREAT DETECTION & RESPONSE

Credential abuse refers to the unauthorized use of valid usernames, passwords, or authentication tokens to access systems and applications. It allows attackers to bypass traditional defenses and operate under the guise of a legitimate user, making detection much more difficult. Once inside, attackers often escalate privileges, move laterally, and exfiltrate data while evading standard security controls.

Attackers can acquire credentials through phishing and business email compromise attacks, malware (e.g., infostealers), brute-force attacks, Dark Web marketplaces, or by exploiting misconfigured identity systems. More advanced techniques include adversary-in-the-middle (AitM) attacks to hijack sessions and MFA fatigue attacks that trick users into approving access.

eSentire monitors user authentication behavior in real time, looking for anomalies such as impossible travel, abnormal access patterns, or sudden privilege changes. When credential abuse is detected, eSentire can disable compromised accounts, revoke session tokens, and enforce MFA reauthentication. Our TRU team continuously updates detection models to stay ahead of evolving abuse techniques.

ITDR is a cybersecurity framework focused on detecting and responding to identity-based threats in real-time. It provides visibility into identity misuse, including credential abuse, privilege escalation, and insider threats, across hybrid environments. ITDR complements existing tools like IAM by identifying threats post-authentication, when attackers are already inside the environment.

IAM enforces access policies, and EDR protects endpoints, but neither can fully detect or contain threats once valid credentials are used maliciously. ITDR fills that gap by continuously monitoring identity activity and executing targeted response actions (e.g., account disablement, token revocation) to stop attacks in progress. It works across cloud, SaaS, and on-premises identity systems.

eSentire’s MDR for Identity detects threats such as credential abuse and account takeover, unauthorized access and privilege escalation, MFA bypass attempts, malicious insider behavior, dormant account exploitation, and OAuth/token-based persistence techniques.

Yes, eSentire automates containment actions at the identity layer, including disabling compromised accounts, revoking access tokens, and triggering reauthentication workflows. Our SOC Cyber Analysts and Elite Threat Hunters also provide human-led investigation and response to ensure complete threat resolution and minimal business disruption.
