Keeps all your domains safe from cyberattacks

The technology is called DMARC, which stands for Domain-based Message Authentication, Reporting & Conformance and is used for maintaining trust between your brand and its customers and partners. It provides a foundation of trust between your brand and everyone on your email contact list, ensuring that the messages coming from your domain name are secure. DMARC gives you control over emails that purport to come from your domain. It acts as a filter for messages that claim to come from your domain but that did not actually originate in your mail servers. This technology lets senders tell email providers which emails really come from them, and further instructs email providers on what to do with messages that fail authentication. It sends reports back to the original sender, letting domain owners know that someone out there is attempting to forge their name for fraudulent activity.

Any organization that operates its own domain name and relies on email to communicate, internally or externally, needs an authentication solution like DMARC. The global volume of email phishing attempts grew by 65 percent in 2017, and it’s not stopping there. You can no longer trust customers and employees to identify phishing emails by bad grammar, suspicious visuals, and other tell-tale indicators. In fact, a recent Intel study showed that of 19,000 respondents, 80 percent incorrectly identified at least one fraudulent email. If your business is under your own domain name, then your entire contact list is at risk. Whether a cybercriminal forges your domain name to obtain sensitive data from customers or impersonates executive leadership to steal financial records from your employees, email headers are the easiest tools to counterfeit. Even if you don’t have an email client set up on your domain, DMARC can help you mitigate the risk of email fraud. Google’s G-Suite follows DMARC protocols and lets users decide how Gmail should treat unauthenticated mail that claims to come from your domain. Remember that since cybercriminals forge email headers, it doesn’t matter whether you actually send emails from your domain or from a commercial email client like Gmail. In both cases, DMARC sets the record straight by verifying that your messages come from the same server. If your business uses a third-party mail server, you still need to deploy DMARC.

Email, as a system, has numerous security flaws that have remained largely unaddressed due to the decentralized nature of the Internet. Cybercriminals can forge either one of these addresses to generate fraudulent emails. DMARC combines two email authentication frameworks to generate an elegant, reliable system for verifying the trustworthiness of both addresses. These are: The Sender Policy Framework (SPF) and DomainKeys Identified Mail Protocol (DKIM). While these two technologies do not provide for reliable email authentication on their own, when combined they provide a powerful framework for aligning domains with Envelope From and Header From addresses. This is where DMARC’s two innovative features, domain alignment and reporting, come into play. Using DMARC, domain owners can control what happens to messages that fail these checks. You can have these message quarantined (sent to the recipient’s spam folder) or rejected (sent directly to the trash). DMARC automatically generates and sends reports to the domain owner for each failed attempt.

The easiest way to implement DMARC is through a third-party deployment service. Vendors like DMARCian.com provide ideal reporting services for low-volume email users interested in protecting a single domain. If your business has multiple domains and sends a high volume of emails on a regular basis, you will need to use an enterprise-level authentication service. If you wish to implement DMARC manually, you need to access your Domain Name Server (DNS) and publish a text like the following: v=DMARC1; p=quarantine; pct=100; rua=mailto:[email protected]

Aggregate DMARC reports do not include any PII or any other sensitive information, however, Forensic Reports may inadvertently leak this type of information. If you are concerned about possible PII exposure only enable Aggregate reporting.
