Why Do Companies Need to Build a DMARC Record and Protect Business Email?
Businesses that use DMARC save time on catching cybercriminals and finding out the illegal usage of their email by hackers. This, in addition to brand trust and authority, the elimination of customer support costs and email fraud, are some of the many benefits of knowing how to setup DMARC and taking the recommended steps.
DMARC makes your customers have private and trusted email communication without the fear of being a cyberattack victim. It will amaze You how much businesses losing their money due to cyber attacks.
- 64% of companies have experienced web-based attacks
- 62% experienced phishing & social engineering attacks
- 59% of companies experienced malicious code and botnets and
- 51% experienced denial of service attacks
DMARC is an open standard enabled on 70% of the world’s inboxes. DMARC setup is also the best best way for businesses to protect their emails from illegitimate usage and cyber attacks.
DMARC is built upon two other authentication protocols: One of which is SPF (Sender Policy Framework) and another one is DKIM (DomainKeys Identified Mail). You should have SPF and DKIM on your Envelope From and Friendly Form domains before proceeding with DMARC.
DMARC (aka Domain-based Message Authentication, Reporting, & Conformance) DMARC is an email authentication standard based on SPF & DKIM protocols. Learning how to setup DMARC and DKIM lets the customer get visibility into how their email domains are used, allowing to catch all the fraud emails that send from an unauthorized server, besides this benefits, it increases email deliverability, gives companies a trust high level that customers wish to communicate without receiving a fraud from them, makes companies not to lose their money on phishing, sending an email to the recipients inbox is also one of the advantages of using DMARC.
DMARC record example
_dmarc v=DMARC1;p=reject;sp=none;pct=100;adkim=r;aspf=r;rua=mailto:[email protected]; ruf=mailto:[email protected];rf=afrf;ri=86400;fo=1
SPF (aka Sender Policy Framework) allows domain owners to choose which email addresses one can send an email from with their domain- it is the “From” header of the email. SPF can catch the unauthorized servers which a hacker sends an email from, furthermore, it protects a real message from the domain owner. With SPF, a receiver can consider the email authentic.
SPF record example
example.com v=spf1 mx ip4:18.104.22.168/32 include:_spf.example.net -all
DKIM (aka DomainKeys Identified Mail) DKIM is an email authentication standard that is associated with a signature checker that a sender inserts into the email message. Sender’s cryptographic signatures are designed for receivers to verify by using DNS-hosted public keys. If the signature is correct and checked, DKIM identifies it as a reliable domain level.
DKIM record example
example._domainkey v=DKIM1; k=rsa; p=public_key
The DMARC protocol allows senders to publish policy records to manage the emails’ reach on inbox or spam box, or rejecting. The policy features that DMARC enables are:
- P=none – None is monitor mode that doesn`t prevent emails from getting into the spam box but only monitors them.
- p= quarantine – Helps you send fraud emails to the spam box.
- P= reject – reject policy is what your company needs to achieve high email protection. It doesn’t allow illegal emails to reach the receiver’s inbox or even spam box.
