Why Hosted MTA-STS?

Hassle Free Hosting

Instead of spinning up a dedicated server and TLS to monitor and maintain, simply point two DNS records and we'll do the rest.

The Security Gap

Email uses opportunistic TLS. If TLS fails or is rejected, inbound mail can fall back in ways that expose traffic to snooping or manipulation.

The Maintenance Gap

MTA-STS enforces TLS and pins your MX servers, but it requires a hosted policy file, valid HTTPS, and ongoing certificate maintenance.

The Hosted Solution

Set two DNS records and DMARC Defender provisions the hosting, TLS, policy file, and management workflow for you.

Simple Deployment

Deploy in minutes with guided DNS instructions

Simply copy the DNS records for each domain and click verify.
