What is an Insider Threat?
An insider threat can happen when someone close to an organization with authorized access misuses that access to negatively impact the organization’s critical information or systems. This person does not necessarily need to be an employee – third party vendors, contractors, and partners could pose a threat as well.
Recent insider threat statistics reveal that 69% say their organizations have experienced an attempted or successful threat or corruption of data in the last 12 months. Discover more Insider Threat Statistics.

Insider Threats FAQs
How many potential insider threat indicators are there?
Any user with internal access to your data could be an insider threat. Vendors, contractors, and employees are all potential insider threats. Suspicious events from specific insider threat indicators include:
- Recruitment: Employees and contractors can be convinced by outside attackers to send sensitive data to a third party.
- Voluntary: Disgruntled and dissatisfied employees can voluntarily send or sell data to a third party without any coercion.
- Unknowing: Due to phishing or social engineering, an individual may disclose sensitive information to a third party.
What advantages do insider threats have over others?
Because insiders have at least basic access to data, they have an advantage over an external threat that must bypass numerous firewalls and intrusion detection monitoring. The level of authorized access depends on the user’s permissions, so a high-privilege user has access to more sensitive information without the need to bypass security rules.
What is not considered a potential insider threat?
External threats are definitely a concern for corporations, but insider threats require a unique strategy that focuses on users with access, rather than users bypassing authorization. Attacks that originate from outsiders with no relationship or basic access to data are not considered insider threats. Note that insiders can help external threats gain access to data either purposely or unintentionally.
