Outbound mail-flow security (DMARC, DKIM, SPF) – reporting to protect impersonation

by | 18th July 2022

The Challenge: 

You receive an email from a client, there is something strange about it. Do you open it? What if your client received an identical email pretending to be from you? Both you and your client open the identical email from the Cyber Criminal, launching malicious content onto the system.  

If you do not filter your emails with outbound mail-flow security, both you and your clients can never fully trust emails you receive from each other.  

The Solution: 

When you send an email, outbound mail-flow security starts the following process:   

The Sender Policy Framework (SPF) stops email messages being sent, pretending to be from your domain name.  

The DomainKeys Identified Mail (DKIM) includes an authentication special signature with your email, verifying throughout your email’s journey from your email box to your recipient’s inbox, that both the email domain and contents have remained unchanged.  

The Domain Message Authentication Reporting and Conformance (DMARC) blocks domain spoofing, stopping Cyber Criminals impersonating anyone at your company.  

This helps to prove that any emails claiming to be from you are from you.  

The Outcome: 

When your clients receive the emails you send them, they can fully trust they are from you and not from Cyber Criminals. Let outbound mail-flow security work for you.
