A recent report analyzed email security solutions' popularity and efficiency over the last four years. According to At-Bay research, the two email solutions that performed the best in their category were Mimecast and Google Workspace.
The dataset used for the analysis includes details from the mid-to-small-size businesses that held an At-Bay policy from mid-2018 up until May 2022, and also experienced a security incident where the attack vector included a malicious email or network security attack against a local email server.
