    FAQs

    Insider Threat Management FAQs

    The “in-a-nutshell” basics you need to know to manage insider threats to your email security.

    Any employee can pose a “threat” via negligence. But insiders with malicious intent can be even more dangerous. In general, the indicators that suggest an individual is moving toward becoming an insider threat are quite similar to the signs that identify a disgruntled employee: they vocally disagree with business policies and/or with their coworkers; they may start working at odd hours, or hours that are unusual compared with their norm; their email communications volume, style or time of day suddenly changes; they’re experienced financial problems or a sudden financial gain. Internal threat protection systems contain analytical engines designed to automatically detect much of this concerning behavior. 

    Are insider threats more dangerous than external threats?

    Whether insider threats or external threats are more dangerous is an ongoing debate among cybersecurity experts that isn’t likely to be resolved any time soon. While most headlines are made from breaches caused by external threats, insiders have access to a business’ most sensitive information; they can wreak havoc intentionally or inadvertently. Most security experts do agree, however, that organizations must protect themselves equally well from insider and external threats. 

    What percentage of cyberattacks are from both insider and external threats?

    Because human error — like clicking on an email link that turns out to be malicious — is often the starting point for a successful cyberattack, the percentage of attacks resulting from insider threats depends on your point of view. Experts’ estimates vary widely, from 60% to 75% and even higher.
