Inbound Protection and Outbound Control because of DMARC!

DMARC Analyzer recognize that the context of what DMARC can do is not always clear. DMARC is about email security. Traditionally this was about inbound protection, where DMARC can be used. Though, DMARC is more about outbound email protection. This article attempts to clarify this and provides information about the differences between inbound and outbound email protection. And, how DMARC fit’s in.

There are 2 types of email protection:

Inbound: These messages are received by your users from senders outside the set of domains associated with your company or organization.

Outbound: These messages are sent by your users to recipients outside the set of domains associated with your company or organization.

Where traditional email protection only secured emails coming in, DMARC goes further in protecting your inbound and outbound email. With DMARC there’s nowadays a possibility to protect emails being send on behalf of your domains. DMARC protects your email channel on domain level basis. This means that the domain owner now has the possibility to determine and secure owned domains with 3 different policies. The 3 policies, “none”, “quarantine” and “reject”, gives you full control of the emails being delivered. With these policies the domain owner can now determine what will happen with all the emails being send on behalf of his domains.

So with DMARC you can protect your inbound and outbound emails, gain full insight in these mailstreams and protect your employees, partners, third-party senders and your customers of being phished or spoofed on behalf of your company name.
