Hosted Email Security for Enterprises
Enforce email encryption so attackers can’t intercept your messages.
MTA-STS Encrypts Incoming Emails
The Mail Transfer Agent-Strict Transport Security (MTA-STS) protocol is a widespread standard that drastically improves email security. It works by enforcing the encryption of emails sent to your domain, ensuring that incoming messages are not received in unsecured cleartext. This prevents cybercriminals from viewing email traffic, tampering with emails, and adding malicious attachments.

Deploy MTA-STS security through DMARC Report
DMARC Report users can establish MTA-STS protocols for incoming emails, ensuring that your organization is protected against some of the most frequent types of email-based attacks. Our solution makes email security easy in six key ways:
How MTA-STS Works
MTA-STS secures email deliverability in two ways:
- It enforces TLS encryption for all incoming emails.
- It provides MX records from an HTTPS-secured server.
The MTA-STS protocol tells any SMTP mail server sending mail to your domain that it will only accept emails over a TLS-encrypted connection. If the sending server and the receiving server fail to negotiate an encrypted channel, the email is simply not delivered – malicious mail won’t arrive in your inbox.
Major email service providers like Microsoft, Oath, and Google rely on MTA-STS to keep their users safe. You can do the same by establishing MTA-STS protocols in your email system. View our detailed implementation guide to learn more.
