The Importance of Having a DMARC Email Authentication

An important element of phishing defenses for any organization, large or small, is DMARC email authentication.

DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. Its main purpose is to mitigate phishing attacks that spoof an organization’s domain and get those emails delivered to inboxes.

Protect Your Business Brand

Email security is important for keeping your employees and customers safe from cybercriminals who might try to steal personal information. Take, for example, someone who sends an email on behalf of your company. It fails DMARC, which means you can take an authoritative action. DMARC is an added layer of email security that can help stop spam and phishing in their tracks, helping companies protect their brands and reputation.

With DMARC, organizations can create a record of authorized senders from their domain, helping to prevent misuse of a company’s brand in phishing attacks. When configured on top of existing SPF and DKIM records, it helps confirm whether one or both of the authentication checks have failed.

Benefits of Using DMARC

Here are 5 great reasons to start utilizing DMARC:

  • Increase deliverability rates and reduce bounce rates
  • Receive comprehensive reports of how email messages are authenticated
  • Identify spammers and prevent malicious emails from reaching inboxes
  • Reduce the chances of your company’s emails from getting flagged as spam
  • Gain better visibility and authority over your domains

Get Started with a Proper DMARC Configuration

Many organizations are striving towards making email security mandatory to prevent the loss of sensitive data and resources. Therefore, it’s important to take into consideration the benefits of DMARC and create a safer email experience.

Configuring your domain with the right email authentication protocols doesn’t have to be complicated. Tangent’s DMARC Director was designed to help you configure DMARC quickly and easily, so you can be on your way to protecting your domain, brand, and reputation. Schedule a demo today.

How DMARC Helps Prevent Email Spoofing and Phishing

When you think of spoofing or phishing emails, you probably associate them with an email attack. But what does this all mean, exactly, and how can your organization avoid them?

A Brief History

As early as the 1970s, spammers were able to get around email filters and eventually grew into a global cybersecurity issue in the 2000s.

To help combat this, email security protocols were introduced to help stop email spoofing and phishing. As a result, many spoofed emails get sent directly to spam or junk folders.

Spoofing and Phishing

If you’ve ever received an email from an unknown sender with a rather suspicious-looking link, chances are it was a phishing email. Phishing emails aim to extract sensitive, personal information. It can be easy to spot a phishing email if it’s from a sender you’re not familiar with, an unrecognizable company or domain, or you’ve noticed a misspelling.

Email spoofing, on the other hand, is used to trick recipients into thinking the email came from a trusted person or entity, such as your employer or bank. A recognizable sender email address is more likely to lead the recipient to click malicious links, open malware attachments, and even send sensitive data. Spoofed email sending addresses that were not sent from your organization can tarnish your brand’s reputation. So how can your organization prevent this?

Email Authentication Protocols

If your domain was being used in an email spoofing attack, would you even know? Organizations can protect their brand and domain by putting email authentication protocols in place.

DKIM, SPF, and DMARC are email authentication technologies that help improve your email deliverability and email security. Without these in place, your organization’s domain is vulnerable to email hackers who are able to send spoofed emails to your customers or employees using your domain.

DKIM, or DomainKeys Identified Mail, works by attaching an encrypted DKIM signature to the email, which is then verified by the receiver or receiving system. Implementing DKIM is a great way to protect your organization, employees, and customers from targeted email attacks

SPF stands for Sender Policy Framework and is another type of email authentication technology. Domain owners use SPF to specify the emails they send are coming from their verified list of email servers. An SPF record verifies the IP address of the sender and compares it to the domain owner.

Domain-based Message Authentication, Reporting and Conformance (DMARC) is a relatively new email authentication policy and reporting policy compared to SPF and DKIM. DMARC works by building upon SPF and DKIM mechanisms to validate the sender of an email. With a DMARC record, senders indicate that their email messages are protected by SPF and/or DKIM. It also instructs the receiver of what to do in the event that SPF or DKIM do not pass, such as sending the email to a junk folder or rejecting the email entirely. Furthermore, DMARC allows the receiver to automatically report a pass and/or fail DMARC evaluation and other details to the email address owner.
