Key Takeaways:
- Tightened DMARC requirements are reshaping the email security landscape, compelling Managed Service Providers (MSPs) to adapt their strategies to better safeguard their small to medium-sized business (SMB) clients.
- Email remains a primary attack vector for cybercriminals, and without proper enforcement of DMARC protocols, SMBs face increased vulnerability to phishing, spoofing, and business email compromise (BEC) attacks.
- MSPs must leverage advanced tools and platforms, like Guardz’s AI-native cybersecurity solution, to offer holistic email protection that ensures compliance with new DMARC requirements and mitigates emerging threats.
The Importance of Email Security in a Threat-Laden Landscape
In the modern digital world, email is a cornerstone of business communication. Unfortunately, it is also a prime target for cybercriminals. For small and medium-sized businesses (SMBs), a successful cyberattack can be devastating, resulting in significant financial harm and even the collapse of operations. Managed Service Providers (MSPs) play a critical role in helping SMBs secure their infrastructure, with email protection being one of the top priorities.
Despite advancements in security measures, email security remains a difficult challenge. According to research by Egress, 94% of Firms Hit by Phishing Attacks in 2023, with SMBs being particularly susceptible due to limited resources and security expertise. While solutions like secure email gateways and spam filters exist, the key to solid email security lies in enforcement policies such as DMARC (Domain-based Message Authentication, Reporting & Conformance). DMARC serves as a mechanism for authenticating the legitimacy of emails sent from a domain, helping to prevent email spoofing, phishing, and related attacks.
What is DMARC and Why It Matters?
DMARC was introduced to improve upon existing email authentication protocols like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). Essentially, DMARC works by allowing domain owners to publish a policy that determines how email servers should handle unauthenticated messages—emails that fail to pass SPF or DKIM checks. These policies can either allow the emails to pass, quarantine them, or reject them outright, thereby giving businesses control over how suspicious emails are treated.
The importance of DMARC cannot be overstated, especially in a time where phishing attacks are becoming more sophisticated and harder to detect. Recent statistics show that 90% of cyberattacks begin with a phishing email, and without proper DMARC enforcement, spoofed emails can easily reach the inboxes of unsuspecting employees. As attackers leverage more refined social engineering tactics, having a solid DMARC policy in place becomes a foundational requirement for organizations of all sizes.
DMARC Requirements and Changes: What’s New?
In 2024, new requirements for DMARC enforcement have been introduced, aiming to create a more secure email ecosystem by mandating stricter policies for email authentication. These changes are particularly important for MSPs managing the cybersecurity needs of SMBs, as they now need to adopt more stringent practices to ensure their clients are not only compliant but also protected against evolving threats.
Key Changes in DMARC Implementation:
- Increased Adoption of Full DMARC Enforcement
Under the new regulations, domain owners are encouraged to move from a “monitor” (p=none) policy to an enforcement policy (p=quarantine or p=reject). The aim is to reduce the number of unauthenticated emails that make it through to recipients. This is a significant shift, as many organizations previously set DMARC policies to “monitor,” meaning they would only observe email behavior without actively preventing spoofed or unauthorized emails. - Mandatory Reporting
A new aspect of the DMARC update is the requirement for domain owners to generate reports on email authentication results. These reports give MSPs valuable insights into how many emails are being spoofed and from which sources, allowing them to act proactively. - Stricter Guidelines for Third-Party Services
Many businesses rely on third-party services to send emails on their behalf (such as marketing platforms or CRM tools). The updated DMARC guidelines emphasize that MSPs need to ensure that these third-party services are properly configured to align with the domain’s authentication policies. Misconfigured services can otherwise fail DMARC checks, causing legitimate emails to be rejected.
The Impact on MSPs: Adapting to New DMARC Requirements
For MSPs managing cybersecurity for SMBs, the new DMARC requirements necessitate a shift in approach. Email remains a top threat vector, and without stringent DMARC policies, SMBs are exposed to substantial risks. Here are several ways these changes impact MSPs and what they can do to address them:
1. Stronger Enforcement Equals Stronger Protection
MSPs are now tasked with ensuring their SMB clients move beyond DMARC policies set to “monitor” mode. Previously, many SMBs resisted full enforcement due to concerns over email deliverability. However, with the updated DMARC guidelines, the stakes have changed—adopting a reject policy can dramatically reduce spoofed emails and enhance overall security.
2. Automated DMARC Reporting: A New Standard
SMBs may lack the expertise to understand complex DMARC reports. MSPs must step in by offering automated reporting services, providing insights into email authentication and flagging any potential security risks. This service allows SMBs to maintain compliance while addressing security gaps without overextending their resources.
3. Mitigating Phishing and BEC Attacks
Phishing remains one of the most common entry points for cybercriminals. By deploying stricter DMARC policies, MSPs can prevent attackers from successfully spoofing their SMB clients’ domains, significantly lowering the risk of phishing and BEC attacks. Research has shown that companies with a properly enforced DMARC policy can reduce the success rate of phishing attempts by 77%.
4. Ensuring Third-Party Compliance
SMBs frequently use third-party services that send emails on their behalf. MSPs must ensure that these services are aligned with the SMBs’ DMARC policies to prevent legitimate emails from being blocked. This requires reviewing and updating SPF and DKIM records to include authorized third-party senders.
Why MSPs Should Act Now
The new DMARC requirements are not just about compliance—they are about creating a more secure email environment. MSPs who fail to implement these changes risk leaving their clients vulnerable to email-based attacks, which can have devastating consequences. Given that SMBs are often targeted due to their limited security infrastructures, MSPs must take proactive steps to improve email security.
The Cost of Non-Compliance
Non-compliance with DMARC enforcement can lead to serious financial consequences for SMBs. BEC attacks are on the rise, and recent reports suggest that the average cost of a successful BEC attack for SMBs is $90,000. Moreover, reputational damage from a phishing or spoofing attack can have long-lasting effects, diminishing customer trust and potentially leading to lost business.
Avoiding Downtime and Loss of Productivity
When spoofed emails reach inboxes, the resulting phishing attempts often lead to account takeovers, malware infections, and even ransomware attacks. These incidents cause significant operational disruptions, with employees unable to access critical systems or being duped into wiring funds to malicious actors. DMARC helps mitigate these risks by stopping the problem at its source—unauthenticated emails.
