Thanks Frank for the thoughtful post. You're assessment did a great job of covering one half of the email security market -- e.g. Business Email Compromise (BEC) represented by products like Proofpoint, Material, and Abnormal, all of which are laser focused on keeping risk out of your inbox.
Data Centric Security (DCS) is the other half of the email security market, which you failed to mention. It's represented by products like Virtru, which is laser focused on protecting your outbox -- so you can easily apply security policy and access controls to sensitive information that must be shared externally with third-parties.
