Human Error: The #1 Cause of Data Loss in Organisations (Not Hackers)

Only human…

When most people think of data loss they are instantly drawn to either hackers hiding in the shadows such as Lisbeth Salander from Girl with the Dragon Tattoo or a hardware failure. But the reality might just surprise you:

Human error is still the leading cause of data breaches; not sophisticated cyberattacks, not failed hardware just everyday human mistakes.

The majority of data breaches that are reported to the ICO are classed as “non-cyber incidents” originating from human error. 

The most common cause of breaches – incorrectly addressed emails

In 2023, the most common incident type across UK organisations was “email sent to the wrong recipient” when taken on a global scale misaddressed emails account for around 16% of all reported data breaches. In fact only this week there are reports that PAX8 a Microsoft reseller for MSPs in the UK has sent an email with every partners information and MS licenses supplied to them.

And its just not email, other human factors that regularly appear in reports to the ICO include:

  • Failure to use BCC
  • Misconfigured Systems
  • Lost paperwork


These all fall under the “non-cyber” breaches banner and make up about 75% of all incidents reported in 2023.

Cyberattacks even begin with Human Error

When an attack is classed as a cyber incident; most of the time a human is still often the starting point. Phishing remains one of the most lucrative methods of cyber criminals to exploit, data from the ICO shows the it accounts for a large portion of incidents, with a major rise year on year.

This can be condensed down to:

  • Humans make mistakes
  • Attackers exploit these flaws
  • Business pays the price
