Insider threats—from employees, contractors, or partners—pose significant risks to U.S. businesses. Whether malicious or accidental, insiders can cause data breaches, fraud, or sabotage.
Why Insider Threats Are Increasing
Remote work, complex cloud environments, and third-party access expand insider risk vectors.
Common Insider Threat Types
- Malicious insiders stealing or destroying data.
- Negligent insiders falling for phishing or mishandling data.
- Compromised insiders with stolen credentials.
Mitigation Strategies
- Implement strict access controls and least privilege principles.
- Monitor user behavior for anomalies using User and Entity Behavior Analytics (UEBA).

- Conduct background checks and enforce separation of duties.
