The mistake

Meet Rachel


Rachel’s busy. Her boss has just dropped a new priority client into her lap, and they want everything done yesterday.

Before starting on the new client, Rachel decides to wrap up a project with an existing client.


Rachel emails the client file


Receives an email reminder from the client


Checks Sent Items and sees she’s emailed the wrong person


Replies to the client that the email has been blocked, and reports the breach internally

The impact

  • $1m in lost revenue
  • 200 hours remediation
  • Rachel leaves the company

An investigation is immediately launched into the breach. The files Rachel had shared with the wrong client were incredibly sensitive. Within a week of the breach, the investigation publishes its findings. Rachel is suspended from her job. Not because of the incident, but because she subsequently lied to her client. All trust had been broken.
