The 10 Biggest and Boldest Insider Threat Incidents


Published September 2021


As the workplace quickly evolves, people are working from anywhere and accessing data everywhere. This shift has dramatically increased many organizations’ exposure to cyber risk. Suddenly, CISOs must manage not just external threats, but countless risks from within.

  • How much these incidents cost the organization they hit
  • Lessons learned from each of these examples to ensure you can better protect your organization
