Securing electronic messaging services, particularly when utilizing third-party services, is crucial for maintaining the integrity and security of your communications.
Limiting who can send on your behalf is crucial to maintaining email reputation, security, and governance, ensuring that your communications are trusted by others while preventing unauthorized senders from spoofing your identity and ruining your reputation.
Industry recommendations are to limit outbound messages from your official sending domain to a single relay point.
This can be provided by a specially configured secured email relay solution or a third-party messaging security solution, such as Microsoft, Mimecast, Proofpoint et al.
It is essential that all third-party messaging partners relay messages through your configured secured email relay to present a single point of reference that can now have DKIM, SPF, DMARC, and other messaging standards applied uniformly.
This will improve your overall reputation in the public messaging industry and allow you to track and remediate any potential issues.
There are multiple security, process, and business integrity reasons why you should not add Third Party Partners to your SPF records.
Look for providers with a history of maintaining high standards of security compliance.
This includes monitoring for failed authentication attempts, unusual message volumes, and unexpected changes in email patterns.
This ensures that emails are transmitted securely over the internet and are protected from eavesdropping and interception.
This adds an extra layer of security to prevent unauthorized access to email accounts.
This helps ensure that your systems are up to date with the latest security patches and configurations.
Regular training sessions and awareness programs can help prevent security incidents caused by human error.
Pay attention to clauses related to data privacy, security, and compliance.
By following these best practices, you can enhance the security of your electronic messaging services when using third-party proxy services and ensure compliance with DKIM, SPF, DMARC, BIMI, and other security standards.
