Background: Mr. Mount has over 30 years experience in email support. His focus has changed with the email threat landscape. Thirty years ago, most corporate email systems were not internet exposed. Twenty years ago, companies were connecting to the internet with minimum threats. Mr. Mount has followed the threat prevention path. In his position as Sr. Engineer Email Cyber Defense, for a major aerospace and defense provider, email delivery was always an underlying responsibility, while responsibility for preventing threats was the primary focus. Mr. Mount also does DKIM/DMARC/SPF. Mr. Mount has experience using Proofpoint PPS and Proofpoint EFD.
