Email Security Breaches: A Worldwide Threat

Reports of corporate data breaches continue to pass through news headlines with such frequency that they barely merit a time slot in the evening news. According to a study conducted by The Ponemon Institute in June 2016, an alarming 85% of respondent businesses admitted that they have experienced a data security breach. Despite the frequency of such security failures, 46% of businesses failed to implement encryption solutions even after suffering a data breach. Organizations experiencing a data breach incurred costs across the board.

  • 74% report loss of customers
  • 59% faced potential litigation
  • 33% faced potential fines
  • 32% experienced a decline in share value

This doesn’t account for the toll on a company’s reputation and brand image, recovery costs after the breach, and the disruption in service during the process.

Because Guardian Digital’s solutions are built on an advanced cloud platform that combines open-source technology with the security expertise of our engineers, the result is a system that updates rapidly and learns over time to protect business email from advanced and persistent threats.

Current Threat Landscape

  • Two-thirds of SMBs have suffered a cyber attack in the past 12 months.
  • Hackers can take advantage of vulnerabilities in operating systems (OS) and applications if they are not properly patched or updated. This puts all of the data on those system and other connected systems at risk.
  • One educational institution that was breached contained it quickly, had no media involvement and spent pennies per record. Yet, the same university experienced a breach of one record when an inadvertent "replay to all" email ended up in the media. That cost over $1,000 to repair the damage for just one record.
  • Email has been the top source of data breaches in the healthcare industry this past year.
