Don’t let your company’s domain fall into the wrong hands. No matter the size of your business, bad actors are utilizing company domains to spoof emails in attacks with surprising skill to gain access to ransom payments, data and IP.

We can help you protect your domain from unauthorized use. Schedule a call below to discuss how we can help you get DMARC easily setup.

How Does DMARC Work?

Domain-based Message Authentication Reporting and Conformance (DMARC) is a free and open technical specification that is used to authenticate an email by aligning SPF and DKIM mechanisms. By having DMARC in place, domain owners large and small can fight business email compromise, phishing and spoofing.

Why Use DMARC for Email?

Email is involved in more than 90% of all network attacks and without DMARC, it can be hard to tell if an email is real or fake. DMARC allows domain owners to protect their domain(s) from unauthorized use by fighting phishing, spoofing, CEO fraud, and Business Email Compromise.

By always sending DMARC compliant email, the operator of an Internet domain can tell the world “everything I send is easy to identify using DMARC—feel free to drop fake email that pretends to be me.”

DMARC’s utility as an anti-spoofing technology stems from a significant innovation; instead of attempting to filter out malicious email, why not provide operators with a way to easily identify legitimate email? DMARC’s promise is to replace the fundamentally flawed “filter out bad” email security model with a “filter in good” model.

Frequently Asked Questions

To start generating DMARC data, you must first publish a DMARC record for each domain you wish to monitor.

A DMARC record exists as part of your Domain Name System (DNS) record, which routes traffic on the internet. You can include additional information in the DNS, like your domain’s DMARC record—a text entry within the DNS record that tells the world your email domain’s policy based on the configured SPF and DKIM protocol.

Sender Policy Framework (SPF) is used to authenticate the sender of an email. With an SPF record in place, Internet Service Providers can verify that a mail server is authorized to send email for a specific domain. An SPF record is a DNS TXT record containing a list of the IP addresses that are allowed to send email on behalf of your domain.

DKIM stands for DomainKeys Identified Mail and is used for the authentication of an email that’s being sent. Like SPF, DKIM is an open standard for email authentication that is used for DMARC alignment. A DKIM record exists in the DNS, but it is a bit more complicated than SPF. DKIM’s advantage is that it can survive forwarding, which makes it superior to SPF and a foundation for securing your email.
