Common Indicators of Email Data Loss

Whether intentional or unintentional, email data loss can have dire consequences. Here are some telltale signs that your sensitive or confidential data has been exposed:

  • Unusual Mail Rules

    An employee is auto-forwarding all business mails to their personal email address. Whether out of negligence or malice, the result is data loss.

  • Suspicious Downloads

    An employee that usually downloads things sparingly has suddenly downloaded 10 documents within half an hour.

  • Incorrect Recipients

    Accidentally replacing an ‘i’ with an ‘e’ in the recipient’s email address means you just sent that quarterly financial report to a stranger.

  • Confidential Data Leaks

    An employee just shared a confidential spreadsheet containing all your customer data with a third-party analyst.
