My Email Communications Security Assessment (MECSA): 2018 Results

This JRC technical report presents the results obtained by the My Email Communications Security Assessment (MECSA) tool. MECSA is an online1 tool developed by the Joint Research Centre to assess the security of email communications between email providers. Email communications continue to be one of the most widespread forms of digital communications with thousands of millions of emails exchanged on a daily basis. It is estimated that 72% of the European population use email either in mobile phones, tablets or computers. It is the means of digital communication used by most Europeans on a daily basis (Special Eurobarometer 462, 2017. Published July 2018.) MECSA is the outcome of our research on the security of email communications. It servers a triple purpose. Firstly, it allows us to monitor the adoption of modern email security standards in the current ecosystem of email providers, assessing their capability to protect the confidentiality, integrity and authenticity of the email exchange amongst them. Secondly, MECSA aims to become a one-stop shop for email users to receive an indication of the capability of their email providers to protect their email exchange in the communication with other providers of the ecosystem. Finally, MECSA aims to become a reference tool for professionals and a mean to promote the adoption of modern email security standards in Europe.JRC.E.3-Cyber and Digital Citizens' Securit
