DMARC Monitoring Services and Their Benefits
If you’re reading this, you already know that email security isn’t something you can gamble with. Chances are that you’ve seen phishing attacks that resulted in a flood of customer complaints, scams that cost organizations millions, and spoofed domains that destroyed reputations.
The question isn’t whether email security matters. It’s how you can prevent malicious actors from forging your email address and fooling the receivers into believing it’s you who has contacted them.
Traditional email authentication mechanisms like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are great for getting started. They are like the first step to verifying email senders and combatting tampering. However, they don’t solve the entire problem. Attackers may still manipulate the “From” address, evade SPF checks using intermediary servers, or exploit misconfigured DNS (Domain Name System) records.
This is why security-conscious organizations should pay extra attention to DMARC technology (Domain-based Message Authentication, Reporting, and Conformance). Unlike SPF or DKIM, this technology allows domain owners to actively enforce email authentication policies and optimize deliverability by beefing up their security mechanisms with a higher-level protocol.
Why Is DMARC Important?
A DMARC record is like an advanced filter. It ensures email messages claiming to come from a particular domain are actually authorized to do so. It has a lot to do with SPF and DKIM, as this protocol validates SPF and DKIM checks when the message is sent. The importance of DMARC is related to auxiliary authentication that DKIM and SPF do not provide:
- SPF only verifies the return-path domain hidden in email headers, not the “From” address that recipients see. This limitation enables malicious actors to spoof the visible sender address and manipulate the recipient.
- DKIM is effective for message modification prevention. However, it doesn’t verify the actual sender’s identity, which unlocks some forging opportunities for attackers unless additional protocols are implemented.
That is why the use of DMARC is pivotal. This protocol aligns SPF and DKIM results with the visible “From” field to ensure the email comes from an authorized sender, has not been altered in transit, and can be deleted or quarantined if unauthorized actions are spotted.
A DMARC record contains a set of instructions that tell email servers what should be done after the message has been checked. Without DMARC, they have no standardized way to handle authentication failures. Some might red-flag unauthenticated emails as spam, but others may still deliver them to inboxes, allowing phishing hazards to slip through. By implementing DMARC with a reject policy (p=reject), domain owners are better positioned to deter fraudulent emails and block impostors.
What Is DMARC Monitoring?
To enable DMARC, you need to publish a DMARC record via your DNS management console. Once the record is prepared and published, email servers processing emails from the specified domain name will start sending you DMARC reports. These contain information on the authentication status of your messages, origin, how many emails have passed the checks, how many have been removed, and more.
DMARC monitoring refers to scrutinizing these reports on a regular basis. By doing so, domain owners can ensure complete DMARC enforcement and take advantage of the full range of benefits unlocked by next-level email authentication.
During DMARC monitoring, you can receive two types of reports:
- Aggregate (the RUA tag). These reports draw a general picture of authentication results and provide group data on SPF and DKIM checks. You’ll get them every 24 hours, regardless of the specific authentication results and pass rates.
- Forensic (the RUF tag). These reports draw your attention to individual emails that have failed to pass the checks. They are generated and sent whenever an authentication failure is detected and cover more details than aggregate reports, including personally identifiable information.
Taking a close look at both report types is essential for DMARC enforcement. They clue you in on how your domain is being used and whether it is being abused so you can take appropriate action for your email security.
The caveat? Manual DMARC monitoring can be ineffective and time-consuming. If you have difficulty reading XML data or are setting up DMARC for a large organization that will likely receive reports galore, brace yourself for many manual analysis challenges and, possibly, an inability to get to the bottom of authentication failures. In addition to that, raw reports do not provide immediate guidance on what you should do in response to the failed SPF and DKIM checks.
To get the hang of DMARC reports without losing your mind, you can turn to paid or free DMARC monitoring services. They make data processing easy (even for non-technical users), transform extensive reports into human-readable insights, and provide recommendations for updating your existing DMARC policies and counteracting malicious actors.
Benefits of Implementing DMARC and Using Monitoring Services
The key thing about DMARC is that it allows your organization to minimize spoofing and fraudulent emails. The authentication protocol is an essential security element that keeps cybercriminals from impersonating your domain and mitigates the losses you could suffer due to business email compromise.
But is DMARC necessary in the presence of email gateways, spam filters, anti-phishing protection, and other advanced cybersecurity solutions? The answer is a resounding YES! No matter how many solutions are already implemented or how impenetrable they seem, you might not know your domain is being abused without DMARC.
Besides, DMARC deployment is a prerequisite for BIMI (Brand Indicators for Message Identification). Even though this email specification is still in the works, implementing it after setting up your DMARC is a great way to refine your brand’s inbox appearance and boost open rates. With BIMI, you will be able to flaunt your logo next to your emails, which can be beneficial for:
- Brand visibility without the hassle of manually maintaining brand indicators
- Email deliverability and improved user engagement
- Increased trustworthiness toward all the messages you send
- Improved consistency for your email campaigns
The benefits of DMARC are the most substantial when the protocol is deployed and maintained with the help of monitoring services. These services enable organizations to fine-tune their DMARC policies in the face of existing domain impersonation attempts, avoid disruptions, and eliminate false positives when it comes to SPF and DKIM checks.
DMARC services can be a blessing for your business if you are looking for:
- Professional DMARC alignment or record setup assistance without the risk of duplicate entries and DNS issues
- Dashboards that break down the data found in aggregate and forensic reports and make it understandable for all decision-makers
- Real-time alerts for situations when SPF/DKIM misalignments or domain impersonation attempts are detected
- Continuous DMARC enforcement with ongoing policy adjustments, spoofing threat mitigation, and BIMI compliance
Despite indescribable practical assistance and automation benefits, you can try to make full use of DMARC on your own. However, implementing the protocol and keeping up with email authentication requirements without monitoring services is harder.
How to Choose the Best DMARC Monitoring Service
If you have decided to implement sender best practices with a monitoring service, you will want to choose the perfect fit for your current DMARC adoption stage and business needs. Here are several tips to use:
- If you haven’t published a DMARC record yet, opt for a service that provides DNS configuration assistance and guided policy enforcement.
- Not all services cover forensic reports. For a bigger picture, choose one that can process data from both aggregate and forensic reports.
- If you have many domains, make sure you have access to dashboard management tools that can cover them all.
- Top DMARC monitoring tools come with real-time alerts. Use a service that can reduce manual effort for your team.
- Check the availability of additional features for compliance with SOC 2 (System and Organization Controls 2) and other security protocols, if necessary.
- Automation and dashboards are useful, but they can’t replace humans. Choose a monitoring service that offers a dedicated support team.
The best way to go is to get started with a free trial. This will let you check out the major features and tools of a DMARC monitoring service and gain a better understanding of whether it is worth switching to.
