Risks of Not Implementing DMARC

October 1, 2022  |  4 min read

Do you know where your domain email comes from? Are spammers attempting to fake your email domain in order to gain access to your account and commit fraud? Are you following optimal email practices to ensure email delivery is high? DMARC answers these issues, allowing you complete control over email delivery for your company’s domain while avoiding DMARC risks. 

DMARC allows email domain owners to manage how their communications are processed, making it more difficult for criminals to spoof messages and make them look to have come from a trustworthy address.  

What would happen without DMARC?  

Email Spoofing   

To prevent email spoofing, domains must have an email authentication system implemented. SPF and DKIM, on the other hand, cannot prevent impersonation of your domain or email spoofing on their own. DMARC is a security component that aids in preventing this. SPF and DKIM protocols are combined to give 100 percent protection against exact-domain attacks.  

Being a victim of a phishing scam.  

Phishing is a deceptive method of obtaining confidential information. Hackers trick victims into performing specified actions by impersonating a legitimate person. According to the Verizon Data Breach Investigations Report 2018, phishing and pretexting account for 93% of data breaches. DBIR credentials are used in 80% of all breaches. Phishing attacks can be avoided with the help of DMARC.   

Is lack of DMARC a vulnerability? 

The accuracy with which you configure your protocol determines the likelihood of your messages being delivered to your clients. Existing flaws in your company’s email security posture can make it more difficult for your communications to be delivered therefore posing DMARC risks. 

 The following are some obvious signs that your DMARC authentication scheme has a flaw: 

  • Deliverability issues with emails 
  • When using online tools, legitimate messages are being flagged as spam by DMARC error prompts. 

Vulnerabilities in your email authentication system might range from basic syntax problems to more complicated issues. In either case, a lack of DMARC is a weakness, and until you troubleshoot these issues and properly set up your protocol, your email security efforts may be rendered ineffective. 

Is DMARC really necessary?  

DMARC risks are increasingly relevant in today’s world, especially as remote-working scenarios become more popular and electronic communication becomes the most common form of business involvement.

Use our DMARC record generator tool to configure DMARC. Skysnag provides user-friendly DMARC analysis software and acts as your professional consultant to help you get as near to a reject policy as rapidly as possible. Allowing you to safeguard your domain’s emails and take control of your delivery.

Here are the five reasons why DMARC is necessary:  

DMARC Aids in the Prevention of Impersonation Attacks  

DMARC helps protect your emails from fraud and impersonation by reducing the likelihood of BEC and domain spoofing attacks. This is because DMARC differs from standard integrated security gateways included with cloud-based email exchange services in that it allows domain owners to specify how they wish receiving servers to respond to emails that fail to comply with SPF/DKIM email authentication protocols.  

DMARC Helps Emails Get Delivered  

DMARC has been shown to enhance email delivery by about 10% over time! You must use DMARC to maintain complete control over your domain by selecting which messages are delivered to your receivers’ inboxes. This prevents bogus emails from being sent and ensures that authentic emails are always delivered on time.  

DMARC Aggregate Reports Assist You in Increasing Your Visibility  

DMARC Aggregate reports can assist you in quickly viewing your authentication findings and mitigating email delivery issues. It allows you to see which sending sources and IP addresses are sending emails on your behalf and failing to authenticate. This also explains why DMARC is essential, as it aids in the detection of rogue IP addresses.  

DMARC Forensic Reports Aid in the Investigation of Forensic Incidents  

When an outgoing email fails SPF or DKIM authentication, DMARC forensic reports are created. In-depth analysis of harmful sources such as malicious IP addresses from impostors that may have attempted to spoof you is provided in forensic reports, allowing you to take action against them and prevent future incidences.   

DMARC Aids in the Enhancement of Your Domain’s Reputation  

A solid domain reputation tells recipient email servers that your emails are real and come from trustworthy sources, making them less likely to be labeled as spam or end up in the rubbish bin. By validating your message sources, DMARC helps you strengthen your domain’s reputation and shows that your domain has expanded support for safe protocols by implementing standard email authentication standards like SPF and DKIM.  

What is the purpose of DMARC?   

DMARC allows a company to publish a policy that describes its email authentication processes and gives receiving mail servers guidance on how to enforce them. Although email fraud is far from the only cyber risk, it is by far the most common attack used by cyber thieves leading to DMARC risks if DMARC is not properly installed.  

Here are the purposes of DMARC: 

Purpose of DMARC?  

To give your customers confidence in your emails  

Essentially, you want everyone on the internet to be able to trust your email messages without having to worry about cybercrime or the troubles that cyber-attacks could cause for your company. To fool their victims into handing up information, cybercriminals are increasingly using well-known brands to send out email blasts using your logo. This is something that DMARC can help you avoid.  

In order to protect your company’s reputation  

To avoid being listed as the sender on email reports, the receiver may not realize the communication is not genuine. DMARC can assist you in avoiding this situation.  

To prevent fraud at the highest levels of government  

Finally, DMARC provides protection against C-Level threats. These are sometimes referred to as ‘Whaling’ and are carried out for the purpose of gaining authority and access within a firm. Because they are similar in nature, whaling assaults are frequently confused with phishing attacks. You can use DMARC to influence the deliverability of Whaling assaults and thereby add “trust” to your domain.
