Email Security


Implementing DMARC can assist in protecting your company from email-based risks.

The more successful your business is, the more well-known your brand grows. Scammers could hijack your domain and use it to send phishing emails and other types of scams in order to take advantage of trust in your brand. Any domain owner who wants to protect their company, their clients, and their reputation must implement DMARC on their domain.

DMARC Explained

Since 2012, the Domain-based Message Authentication Reporting and Conformance (DMARC) protocol has been used to confirm that an email is legitimate. DMARC, coupled with a Sender Policy Framework (SPF) and a DKIM public cryptographic key, are essential components when it comes to protecting your email. Although DMARC is an open standard that can be freely implemented by any domain owner, doing so correctly calls for technical expertise.

The Three DMARC Policies

There are three different DMARC policies you can choose from. Each one instructs your email servers how to handle unauthorized messages sent from your domain.

  • p=none
    Monitor the unauthorized emails but take no action.
  • p=quarantine
    Send unauthorized emails directly to spam.
  • p=reject
    Do not deliver unauthorized emails.

Do You Need DMARC?

The most common method for carrying out ransomware, malware, and phishing attacks is to deliver them via email. Even though DMARC is successful in preventing this and does not cost any money to set up, just 10% of companies are thought to currently have a DMARC policy in place. A DMARC policy guards email recipients from people who would abuse trust in your domain. Additionally, by preventing the association of your domain with criminal activity, you help to safeguard your business’s good reputation.

DMARC provides a simple method to authenticate legitimate emails from your domain. This strategy of whitelisting legitimate emails is significantly more reliable than depending on individual email servers’ spam filters.
