Some threat actors can go as far as infiltrating your workforce themselves or turning an insider towards their cause/goal. Insiders are a particularly nasty threat to any organization’s cybersecurity because of the amount of access they’d have when working from within.
Insider threats are users with legitimate access to company assets who use that access, whether maliciously or unintentionally, to cause harm to the business. Insider threats aren’t necessarily current employees, they can also be former employees, contractors or partners who have access to an organization’s systems or data.
