Protect inbound transport

You've checked your outbound authentication. But without MTA-STS and TLS-RPT, mail delivered to assistnetworks.co.uk isn't protected against transport downgrade attacks. Receiver Shield helps you deploy, monitor, and safely enforce transport security.

Know when your DNS records change

The check you just ran shows your current configuration. But DNS records change, sometimes without you knowing. A well-meaning IT change, a third-party provider update, or an unauthorized modification can break your email delivery overnight.

Configuration Drift

IT changes that accidentally break authentication

Provider Updates

Third-party services changing their SPF includes

Unauthorized Changes

Attackers modifying records to send as you

DMARCTrust monitors your DNS records continuously. When something changes, you get an email alert with exactly what changed and why it matters. No more surprises when customers complain their emails bounced.
