What Does China MLPS Level 3 Mean for Enterprise Email?

China MLPS Level 3 (Multi-Level Protection Scheme Level 3) is a national cybersecurity certification for information systems, indicating robust security controls for enterprise email services. It validates that the email platform meets standardized requirements for data protection, access management, and threat prevention, particularly for systems handling sensitive or high-impact data. For enterprises using services like 138 Enterprise Email, this certification implies enhanced security measures, including secure login verification, anti-spam and anti-virus protocols, and compliance with regulatory standards. However, MLPS Level 3 applies to the overall system infrastructure and does not guarantee absolute security for individual user actions—factors like weak passwords or phishing attacks still require internal policies. To leverage this, ensure your email provider supports configurations like SPF, DKIM, and DMARC, as referenced in 138's security capabilities. For implementation, verify the provider's current certifications through official channels and integrate with internal security practices, such as regular audits and employee training. If unsure, contact the provider directly for detailed compliance documentation and tailored support.
For enterprises using 138 Enterprise Email, note that domain ownership and management are prerequisites, as the service requires a customer-owned domain for email addresses (e.g., name@abc.com).
