Email Security Essentials

Understanding these key protections can help safeguard your organization from email-based threats.

SPF

Sender Policy Framework acts like a guest list for your domain, controlling which servers can send email on your behalf and blocking imposters.

Impact: Prevents email spoofing and phishing attacks using your domain name.

DKIM

DomainKeys Identified Mail digitally signs your messages, providing recipients proof that your emails haven't been tampered with in transit.

Impact: Ensures message integrity and helps build domain reputation.

DMARC

Domain-based Message Authentication acts as your email bouncer, telling receiving servers exactly what to do with messages that fail authentication.

Impact: Provides visibility into email threats and protects your domain from being used in fraud.

MTA-STS

Mail Transfer Agent Strict Transport Security creates an encrypted tunnel for your email, preventing eavesdropping and man-in-the-middle attacks.

Impact: Safeguards email transmission with strong encryption.

BIMI

Brand Indicators for Message Identification showcases your logo in recipients' inboxes, making your authentic emails instantly recognizable.

Impact: Enhances brand recognition and increases user trust in your communications.

MX Records

Mail Exchange records are like postal routing instructions, ensuring incoming messages reach the correct servers for your domain.

Impact: Forms the foundation of your email infrastructure.

This assessment checks published email security configuration. Combine its findings with message headers and your sending service settings; a passing DNS check does not guarantee inbox delivery or mailbox security.

Follow our SPF, DKIM, and DMARC setup guide to review the records, or read how to check whether your email is secure for the wider checklist. For implementation and ongoing monitoring, explore CyberITEX email security services.
