Back when email was on-prem, Secure Email Gateways were the standard. They protected your email server, using a security stack designed specifically for on-prem email. This was effective.
But email is no longer on-prem. It's in the cloud. And gateways securing email at the perimeter is no longer tenable. With cloud email, what's required is a modern security architecture that's designed to block internal threats.
Further, SEGs require you to change your MX records, which is public knowledge. Essentially, anyone can look up your security. A hacker has the code to your alarm system.
When email moved to the cloud, SEGs were the proverbial square peg in a round hole. No matter how much they try, it just doesn't work.
