Protect your email domain from phishing abuse

Using DNS records such as SPF, DKIM and DMARC, companies can ensure that trustworthy emails are clearly distinguishable from malicious emails.
Virtually all companies are affected by phishing attacks today. And these cyberattacks are becoming increasingly authentic, not least with the help of AI.
Google and Yahoo are clear: Since June 2024, these email providers have rejected all emails that do not originate from mail servers that comply with the SPF/DKIM/DMARC standards.

SPF
SPF (Sender Policy Framework) prevents email spoofing by verifying incoming emails from authorized IP addresses. This allows you to specify which email servers are authorized to send emails on behalf of your domain.

DKIM
DKIM (DomainKeys Identified Mail) offers companies the ability to take responsibility for message delivery. This is achieved by adding a verifiable digital signature to the header of an email message.

DMARC
DMARC (Domain-based Message Authentication, Reporting & Conformance) builds on SPF and DKIM and ensures that the displayed sender is trustworthy. DMARC allows you to specify how your emails should be handled if they fail SPF or DKIM checks. Without DMARC, you cannot see who or what is sending emails on behalf of your domain.

Email is the most popular form of communication, but it also plays a key role in many cyberattacks such as phishing, spoofing, and business email attacks (e.g., invoice scamming). The Domain Security Check determines whether your domain is adequately protected.
