The State of Email Security 2020

Global business is interspersed with a diversity of industrial sectors, united by a single, common communication thread that is key to any business: email connectivity.
Email continues to be the most popular attack vector, via organizations at their email perimeters, from inside the organization (through compromised accounts, vulnerable insiders, social engineering), or beyond the organization's perimeters (the domains they own and their brands via impersonation).
To add to the complexity, many global corporations have been forced to adopt remote working policies for office-based employees to help ensure the safety of the workforce during the COVID-19 pandemic, and threat actors have followed them home. An increase in the variety and volume of attacks is inevitable given the desire of financially- and criminally motivated actors to obtain personal and confidential information.
