What Are The Best DMARC Tools?

Email threats grow day by day and people are looking for ways to avoid spam, spoofing, and phishing. On the other hand for business owners, particularly those who own multiple domains, you want to make sure that your domain is not being abused in phishing and spoofing attacks. Business owners who want to future-proof their business from hackers should ensure that users only receive verified emails from your end linked to your domain name. The need for such an automated system that is built to perform this function grows daily. Luckily for you, such tools exist.

DMARC tools are a great way to prevent hackers and other potential attackers from abusing your domain in their spoofing and phishing attacks. DMARC stands for "Domain-based Message Authentication, Reporting, and Conformance", these tools are used to authenticate emails using your domain. Essentially, the tools help you create key authentication protocols to form a standard of conformation. They will then check emails to determine if the email conforms to email authentication standards.

There is a wide range of DMARC tools available today that help companies secure their domains and monitor emails that are sent using their email domain. Each DMARC tool has its own features and benefits and varies according to your needs. Some work by monitoring only, others will perform an in-depth analysis of your outbound emails, some provide domain-based packages, others provide packages based on email volume to be monitored, while some may provide a combination of both, some may provide additional professional services while others may be a self-serve product.

Here we'll be discussing some of the most popular DMARC tools available today and what they can do for you. The best DMARC tools in 2022 are as follows:

What Do DMARC Tools Do?

DMARC, as mentioned earlier, is a type of free and open technical specification that allows you to authenticate emails being sent using your domain. Domain owners need to combat hackers that abuse your domain in phishing and spoofing attacks.

DMARC domains will allow you to prevent these fraudulent emails from being sent that claim to be from your domain when in actuality, they are not. DMARC reports should be able to tell you what servers or third-party apps are sending emails using your domains, what percent of these emails are DMARC authenticated and what percent fail DMARC authentication.

How Does DMARC Authentication Work?

DMARC authentication works using SPF and DKIM mechanisms.

SPF stands for Sender Policy Framework; it is used to authenticate the email sender. An SPF record is a txt record contained in your DNS that enlists a number of IP addresses that are allowed to send emails using your domain. You need to publish this SPF record in your DNS to notify the receiving server of what domains are allowed to send emails.

Each email you send has an associated return path header. This return path is used to send email delivery notifications. The sender's server domain path is extracted to identify its domain and its DNS record details. If the fetched server's IP address matches the ones listed in the SPF record then it is passed onto SPF validation. In the scenario that it doesn't match the IP then the server you use will decide what action to take.

The second authentication mechanism is DKIM. DKIM stands for DomainKeys Identified Mail. This is similar to SPF as it is also added as a txt record in your DNS. This txt record contains a public key that is used by servers to verify a message's signature.

DKIM adds a signature header to your emails that is encrypted and secure. It contains the information needed to verify the signature. The original email server contains the private DKIM key, the other half being the public DKIM key at the receiving server. The receiving server will in this way detect the DKIM signature and look up the public DKIM key in the DNS. Once the key is located it is used to decrypt the DKIM signature, If it matches the DKIM is verified.

Finally, we come to DMARC itself. DMARC works in conjunction with both SPF and DKIM records which means that in order to configure a DMARC record you must first set up an SPF and DKIM record. When a recipient server receives an email, it will check the DMARC record according to both the SPF and DKIM mechanisms. Therefore it will:

  1. Validate the IP address of the sender in the SPF records
  2. Validate the DKIM signature of the email received.

A DMARC record is what defines the DMARC rulesets. In order to deploy DMARC, you must first create this DMARC record. This is a text entry in your DNS that contains your email domain policy following your SPD and DKIM status. DMARC alignment occurs when DMARC authenticates either both or one of SPF and DKIM.

A DMARC record will also create an XML record using your email servers, you can use this XML report with your DMARC tools to get insight into your domain email. These XML reports can be incredibly complex and making sense of them can be tricky, this is where DMARC tools step in. They help simplify this information and give you a visual display of your data.

What Happens If DMARC Tools Are Not Used?

DMARC allows domain users to verify the emails sent from their end and to protect their domain from being used in phishing, spoofing, and fraudulent emails. When you incorporate DMARC into your security controls then you can stop fraudulent emails in their tracks, increase your brand reliability and get more visibility into your domain usage across the internet.

But on the off chance that DMARC is not enabled for your domain, your domain will not be protected from such spoofing and impersonation. Today, more than 70% of all email inboxes worldwide use the standard to detect fraudulent email attacks. When a DMARC policy is not enforced, organizations can not:

  • Protect their customers from phishing attacks
  • Mitigate the chances of brand abuse and scams in your name
  • Reduce the chances of malware attacks and ransomware attacks
  • Get complete sight into your email channel
  • Get visibility on the usage of your email domain across the internet
  • Make your email easy to identify and verify

What are the DMARC Tool Types?

There are three main types of DMARC tools in usage today namely the DMARC analysis tools, DMARC monitoring tools, and DMARC testing tools.

  • DMARC Analysis Tools: As the name suggests, DMARC analysis tools provide users with easy-to-use analyzing software that guides them to work with DMARC policies and helps organizations manage complex DMARC deployment. Analyzing and getting insights from the DMARC reports processed is vital to improving your overall online security strategy. Through the analysis of DMARC reports using this software, you can easily identify your email streams, successfully determine illegal sources of emails misusing your domain and make sure all legal sources are authenticated and verified. These will help uncover anyone using your domain without authorization and block the delivery of unauthenticated email servers.

  • DMARC Monitoring Tools: DMARC monitoring tools are used to review DMARC reports to check for unauthorized usage of your domain. It will allow for real-time analysis of mail sent from your domain. It will further identify whether or not the mail has successfully been verified through SPF, DKIM, and DMARC. If you are new to the concept of DMARCs then you might not be aware that monitoring them is super important. It is crucial to monitor your DMARC reports, even in the scenario that you change your sensing services, you must have a system that monitors these changes. Some DMARC monitoring tools will also allow for BIMI, a type of email verification method that adds a logo of your brand in your verified emails thereby increasing brand recognition and building consumer trust.

  • DMARC Testing Tools: DMARC testing tools are more focused on the testing and validation of DMARC records of any given domain and to test if the text record is valid and published correctly. This will help identify if your record has been published correctly, to see that your records are formatted correctly, and to figure out where your DMARC reports are being sent. Finding the right tool for DMARC can be a challenge since there are a number of tools available today. But thankfully a lot of DMARC tools have a free trial available for a short time that you can use to evaluate the tool and see if it matches your business needs or not. Being secure online is a challenge and taking the right steps to protect yourself from spam or other nefarious activities will not only be to your benefit but will also help the business grow as well.
