How can you secure your email authentication protocols?

MTA-STS (Mail Transfer Agent Strict Transport Security) looks promising. MTA-STS strengthens email transport security by enforcing strict transport layer encryption and authentication. Unlike SPF and DKIM that focus on sender verification, MTA-STS ensures that the connection between email servers is secure and encrypted, reducing the risk of interception and tampering. This protocol is particularly effective against man-in-the-middle attacks, where attackers can intercept or alter emails in transit. By specifying that emails should only be sent over secure connections, it ensures that even if a sender's SPF or DKIM checks pass, the email won't be compromised during transit.

To get started, I'll need some more information from you: Which email authentication protocols do you want to enable? (SPF, DKIM, DMARC, BIMI) Who is your domain name registrar or DNS provider? (e.g., GoDaddy, Google Domains, Bluehost)

Communicate any changes to your email sending infrastructure or authentication protocols to relevant parties. Document your testing and monitoring procedures for future reference and troubleshooting. By following these steps, you can ensure your email authentication protocols are working effectively and protecting your domain from spoofing and spam. Remember, it's an ongoing process, so regular testing and monitoring are key to maintaining optimal email deliverability and security.

Regular Training: Schedule security awareness sessions to keep users updated on new phishing tricks and best practices. Real-life Examples: Share common phishing scenarios and dissect them together to build awareness. Open Communication: Encourage users to ask questions and report any concerns without fear.

API-enabled tools are essential for stopping phishing attacks that can compromise your cloud email security. They connects directly to your email provider via API and scans every inbound, outbound, and internal email and file before they reach the users or leave the organization. They uses multiple layers of anti-phishing technologies, including sandboxing, machine learning, and threat intelligence, to detect and block known and zero-day threats.
