DomainKeys is an older technology that was combined with Cisco’s Identified Internet Mail (IIM) to develop DKIM—an email authentication protocol that prevents phishing emails sent from your domain from reaching recipients’ primary inboxes. Moreover, DKIM also ensures that nobody tampers with the message in transit. People often use these terms interchangeably, but let’s figure out…
DMARC authentication has become the norm in the cyber world, thanks to the revised email-sending policies introduced by Google and Yahoo. But what really makes this email authentication protocol a cult favorite? Apart from adding a layer of defense against unauthorized emails on your sender program and malicious cyberattacks, DMARC (Domain-based Message Authentication, Reporting, and…
In 2023, as many as 45.6% of total emails were identified as spam. While CISOs and technology enthusiasts are trying their best to ward off these attacks, cybercriminals are not behind in exercising their brain muscles to come up with newer ways of exploitation. One such relatively recent technique is a DKIM replay attack, where…

Organizations often treat cybersecurity as a siloed function rather than a measure that needs to be practiced across departments and tiers. The year 2023 reported a global data breach cost of $4.45 million, and the United States encountered the highest average data breach cost, amounting to $9.48 million. While we don’t deny that your CISOs…
Does your organization send more than 5000 emails per day? Does it struggle to keep phishing and spoofing at bay despite implementing email authentication protocols— SPF, DKIM, and DMARC? Well, we understand that there is no foolproof way of preventing these cybersecurity attacks, but you certainly can limit their frequency and impact. You’d be surprised…
Emails are forwarded more often than we realize, and while DKIM isn’t affected by email forwarding, SPF and DMARC may break. For SPF, you create a list of senders officially authorized to send emails on your behalf. When an email is forwarded, the initial recipient becomes the sender; so, if the initial recipient’s IP address…
It was not long ago that Google and Yahoo revamped their sender policies and made best practices a mandatory requirement. For instance, until October 2023, measures like implementing email authentication protocols—SPF, DKIM, and DMARC were “nice to have.” However, starting in February 2024, authenticating their domains with these protocols is no longer an option but…
