DMARC and Email Security

Protecting your email system can be a complex task, especially if you don’t have the right tools in place. Cyber attackers have a plethora of hostile methods they use to disrupt company operations, which can include anything from sending emails from your domain to intercepting emails and altering them, all without anyone’s knowledge.

If you don’t have the right digital security solutions in place, it's almost impossible to identify who is sending emails from a domain, whether it’s from legitimate & illegitimate sources. While this initially might sound insignificant, a cyber attacker’s invasive methods can pose serious threats to your business, such as:

  • Deposit Fraud - Incorrect bank details that are falsely associated with a transaction and attackers redirect the money.

  • Identity Theft - Users are tricked into leaking their identity to an attacker.

  • Ransomware distribution - Users & staff are lured into installing ransomware from a legitimate-looking email.

  • Brand damage - Fraud on a company's behalf causes immense brand damage & financial losses.

What is DMARC and how does it protect me?

DMARC was created by the email industry to put control over email authorisation and authentication back in the organisation's hands. What DMARC does is instruct receiving servers how to apply two mechanisms to authenticate email. On top of this, it provides a way for organizations to see which servers are sending email on your behalf.

The two mechanisms for authentications are SPF and DKIM, and both need to pass before an email is considered legitimate. Simply put, SPF tells receivers which servers are allowed to send email for an organisation. DKIM is a way to sign a mail letting the receiver know that the email was received and that it came from the organisation holding the signature.
