Insider Threats Abuse Trusted Paths Without Identity Validation

Dec 22, 2025

Failure Pattern

Insiders do not need to break encryption or bypass controls (insider threats). They use trusted systems and credentials that security tools blindly accept.

 

What We See in the Field

An insider or compromised employee endpoint accesses sensitive systems using valid credentials. Monitoring tools treat this as legitimate activity. Detection occurs only after damage is done.

 

Underlying Causes

Trust in internal devices
Credentials granting broad access
Lack of per-session identity verification
Blind reliance on logins
Flat internal trust zones

 

Trust-Native Network Resolution

DTL enforces device identity for every session. Insider threats as actions cannot piggyback on trusted endpoints. Access is limited to cryptographically verified workloads.

 

Broken Trust Assumption

This failure pattern has played out repeatedly in real security incidents—not because of missing tools, but because of how trust is assigned.

In breaches such as SolarWinds, Capital One, Okta, and MOVEit, attackers did not bypass security controls. They operated through them, using valid identities, trusted credentials, signed code, and encrypted sessions. Security systems accepted these signals as proof of legitimacy, allowing malicious behavior to proceed.

The common thread across these incidents is structural: identity was assumed based on trust signals, not proven at the moment of execution.
