Misdirected emails: people's mistakes lead to data loss.

When an employee accidentally sends an email to the wrong person, they put their organization at risk of regulatory breaches, financial penalties and reputational damage. Misdirected emails are one of the most common breaches reported under GDPR and can’t be prevented with traditional DLP platforms or Secure Email Gateways.

Human error is the #1 cause of data breaches.

Modern enterprises stake their reputations on how well they manage their own and their customers’ data. Failing to invest in security technology that prevents misdirected emails puts future revenues and existing customer relationships in danger.


86% of reported data breaches stem from human error.


3,500 misdirected emails are sent every year in the average enterprise.


The average cost of a data breach is $3.86m.
