Many companies today still don't see the need for email security. They think this way even though it's a vital part of cybersecurity. What’s more, they fail to grasp the reality of under-prioritizing email security.
Email remains the primary communication channel for most organizations, but it was never designed with modern security requirements in mind. While protocols such as SPF, DKIM, and DMARC help verify sender identity, they do not protect emails while they are traveling between mail servers. This is where MTA-STS (Mail Transfer Agent Strict Transport Security) plays a crucial role.
