What is an insider threat?
An insider threat is a security risk originating from someone with legitimate access to an organization's systems, an employee, contractor, or partner, who misuses that access intentionally or whose credentials are compromised by an external actor.

Insider threats are uniquely difficult to detect because the activity uses legitimate credentials and may resemble normal work. The category includes malicious insiders (data theft, sabotage, fraud), negligent insiders (accidental disclosure, policy violations), and compromised insiders (account takeover by external actors using legitimate credentials). Investigation requires context across identity, endpoint, email, and data-access systems.
How Command Zero handles Insider Threat.
Insider threat is one of Command Zero's primary investigation lanes. Expert questions correlate user behavior across systems, what was accessed, when, from where, in what sequence, to surface patterns inconsistent with the user's role and history. The Question-based method handles the nuance these cases demand: every step is logged, every conclusion is supported by evidence, and the investigation audit trail satisfies HR, Legal, and forensic requirements. The full investigation lifecycle support is critical here, since insider cases routinely escalate to Tier-3 and to incident response.
