Accidental Data Loss Prevention

Prevent Accidental Data Loss with Human Layer Security.

Misdirected email is the #1 cause of accidental data loss according to the ICO. Learn how Tessian stops accidental data loss that rule-based DLP solutions fail to detect.



Why does accidental data loss matter?


On average, a 1,000-employee organization sends out 800 misdirected emails in a year.


Simple errors like typing in a wrong email recipient or attaching the wrong file containing sensitive data can result in serious consequences. Misdirected emails are a big challenge to enterprises as these are substantially under-reported.


Accidental data loss through misdirected email and wrong attachments results in loss of trust and reputation, and can have financial and compliance implications.

What conventional DLP solutions cannot solve for:

  • Automatic breach detection and prevention

    Rule-based DLP tools detect sensitive data strictly based on predefined data classification policies, filters and dictionaries.

    But, what happens if the sensitive data being shared over email has not been classified, or authorized data is shared with the wrong party? Rules have no way of detecting the right receivers or autocorrect errors.

  • Contextual alerts and training

    Modern DLP tools need to go beyond just simple statistical analysis and correlation of rules to detect accidental data loss caused by human error. They need to prevent risky behavior through contextual alerts to educate users on why an email is flagged.

    Tessian delivers in-the-moment, contextual alerts to flag misdirected emails and misattached files using machine learning. The alerts are automated and highly targeted, resulting in low flag rates.

  • Minimize impact on business operation

    Traditional approaches to accidental data loss have come at the expense of user experience as annoying and unintelligent pop-ups cause user fatigue.

    Rule-based approaches that try to limit sharing of legitimate data are restrictive and typically impact productivity due to their high number of alerts. For administrators, creating manual rules for every foreseeable use case is not only resource-intensive but can also lead to data blindspots.
