Identity Threat Detection and Response Platform.
Identity Threat Detection and Response, or ITDR, helps security teams detect and respond when identity access becomes risky or compromised. It focuses on signals such as abnormal authentication, privilege changes, lateral movement, suspicious token use, and identity behavior that does not match normal context.
The ITDR cycle.
The problem
Why identity threats are hard to catch.
Many times a valid identity is more than enough for an attacker. Compromised credentials, abused tokens, over-permissioned accounts, stale service principals, and unmanaged AI agents can all create paths into sensitive systems. Traditional tools may see the log event, but miss the identity story around it.
That is the work ITDR is meant to support.
Security teams need to know:
- Which identity was involved?
- What access did it have?
- Was the activity normal for that identity?
- Did the risk build over time?
- Which systems are now exposed?
- What response action is safe to take?
Signals
ITDR signals security teams should watch.
Common identity threat signals include:
Impossible travel
MFA fatigue
Credential stuffing
Abnormal privilege changes
Dormant accounts becoming active
Suspicious token use
New access paths after federation or role changes
AI agents using credentials or tools in unusual ways
Non-human identities acting outside expected patterns
Any one of these can be noise. What makes it a threat is the sequence, and the identity it belongs to.
The module
What 8Layers Thor does.
Thor is the 8Layers module for identity threat detection, investigation, and response.
The point is not another alert queue. The point is a clearer investigation workspace for identity-driven incidents.
Explore ThorIt helps teams:
Detect identity threats across human and non-human identities.
Correlate behavior and access signals over time.
Surface identity kill-chain activity earlier.
Investigate incidents with timelines and causality graphs.
Understand affected identities, systems, and access paths.
Respond by killing sessions, revoking tokens, or scrambling credentials.
Every identity
ITDR for human and non-human identities.
Identity threats do not stop with employees.
Service accounts, API keys, OAuth tokens, machine identities, and AI agents can all be abused. They can also be harder to review because they do not follow normal joiner, mover, leaver workflows.
8Layers brings those identities into the same detection and investigation model as human users.
Where it fits
ITDR vs SIEM, EDR, IAM, and PAM.
ITDR does not replace any of them. It fills the identity context gap between access management and security operations.
Response & evidence
Response that stays tied to context.
Fast response is useful only when teams understand the blast radius.
8Layers helps analysts see what happened, which identities and systems are affected, and which action makes sense. That may mean revoking a token, killing a session, scrambling credentials, or documenting a risk waiver when remediation is not immediate.
Compliance value.
Identity incidents often create audit questions later. Who had access? What changed? What was reviewed? Which control failed? What remediation happened?
8Layers connects ITDR activity with compliance evidence so teams can document investigation, response, exceptions, and remediation history.

Frequently asked questions
ITDR stands for Identity Threat Detection and Response. It helps security teams detect, investigate, and respond to threats involving human and non-human identities.
Identity is a primary attack path. Attackers can use valid credentials, tokens, service accounts, or over-permissioned identities to move through systems without triggering traditional alerts.
No. ITDR adds identity-specific context to security operations. SIEM and EDR still matter, but they may not explain identity risk, ownership, access paths, and posture.
8Layers Thor detects identity threats, correlates activity over time, gives analysts an investigation workspace, and supports response actions such as token revocation and session termination.
