Did you know that there’s more to DMARC implementation than just the policies that determine what happens to emails that don’t pass authentication checks (SPF and DKIM)? It is the reporting feature of DMARC that sets the tone for the overall effectiveness of your email security strategy. DMARC reports offer comprehensive insights into how emails claiming to come from your domain are being handled by their recipients and the ones that fail DMARC, SPF, or DKIM validation, providing a clear view of both legitimate and fraudulent activities.

DMARC has already gained the attention it deserves, owing to its efficiency in combatting phishing and spoofing attacks. But the journey wasn’t fast and steady from the beginning. It all started when SPF came into play, followed by the amalgamation of Yahoo’s DomainKeys and Cisco’s Identified Internet Mail (IIM). This blog covers the journey of all three email authentication protocols in detail.
Are you struggling to safeguard your organization’s data from the plague caused by malicious attacks such as spoofing, DDoS, phishing, malware, etc.? In your pursuit of a secure and resilient future for your organization, we are sure you must have come across the term “cyber security strategy” quite often! Do you think it is just another buzzword, or does it carry real significance?

Sometimes, Google Calendar invites don’t pass DMARC authentication checks because when the recipient replies to the invitation, the response is sent back through Google’s servers. Since the ‘From’ address and the originating servers don’t align, the Google Calendar invitation gets rejected as the sending domain’s DMARC policy instructs so.
How do you stay one step ahead in a world where cybersecurity threats evolve faster than a click? One of the best ways to stay on top of your cybersecurity game is to cultivate a comprehensive understanding of the various determinants that shape the cybersecurity landscape—major threats, emerging technologies, regulatory changes, etc. And what better way to gain insights into all of this and more than by attending conferences?
DMARC failure reports give insights into why emails failed DMARC checks and show where the trouble is to help you fix it. Invalid DMARC records fail to filter out phishing and spoofing emails. So, ensure your SPF and DKIM settings are correct, address alignment issues, and manage subdomains carefully.
