All email security aspects in one overview

The Mailhardener email hardening suite gives you a full overview of the email security status your domain.

It requires no software to be installed, and you keep your existing email provider. We act merely as a reporting beacon, we cannot see any content of the emails.

Email monitoring (DMARC)

The email monitoring feature gives insight into all emails being send using your domain name in the sender address.

This includes the email send from your email server, and third parties such as your marketing platform, billing system and reporting tools, but also unauthorised senders such as spammers or fraudsters.

The unique Mailhardener self-learning algorithm if the first to accurately distinguish forwarding email services from malicious senders, which greatly reduces false positives.

DMARC reports show you every email sender using your domain name.

TLS reporting

Mailhardener is one of the first to offer fully featured TLS reporting using the TLS-RPT standard.

This will give insight in TLS failures encountered by email servers attempting to deliver email to your domain.

Mailhardener will aggregate, process and enrich TLS-RPT reports and automatically warn you about any problems that are reported by email senders.

DNS change monitoring

Reports show that many high impact fraud cases were possible due to unauthorised changes made to a domains settings (DNS).

Mailhardener will monitor all email related DNS features, and notify you when a change is detected.

The notification will also give you a breakdown of what difference the change will make to your email protection.

Hosted MTA-STS

MTA-STS is an email security standard that mitigates DNS based attacks where attackers could read or manipulate email addressed to your domain.

Deploying MTA-STS can be challenging for organisations due to its strict implementation requirements. To overcome this, Mailhardener offers hosted MTA-STS services that allows any domain to adopt MTA-STS in less than 5 minutes, with zero maintenance.

Report breakdown

There is more than one way to prevent unauthorised email, and many different reasons why a receiving system might decide to accept or reject your email.

The report analysis tool gives you a breakdown in easy to understand English of how the receivers processed the email and why it did or did not accept the email.

Domain inspector

Most of the email fraud prevention is set up in your domain settings, so naturally this is an important part to get right.

There are many different settings though, and even more subtle ways in which configuration mistakes can be made.

The Mailhardener domain inspector will show you exactly how your domain is setup, with easy to read English breakdown.

It also detects common made mistakes, so you don't accidentally make them.
