Is Enterprise Email Completely Secure?

No, enterprise email is not completely secure by default—it requires proper configuration and ongoing management. While 138 Enterprise Email provides built-in security features like SPF, DKIM, and DMARC authentication, weak passwords, misconfigured forwarding rules, or compromised employee accounts can still expose risks. For optimal protection, enable multi-factor authentication, use client-specific passwords for third-party apps, and regularly review login logs and sent items. Note: Security also depends on user behavior and internal policies—phishing training and external verification for high-risk actions (like payment changes) are recommended. If you suspect an account breach, change passwords immediately and check auto-forwarding rules. For advanced security needs or compliance validation (e.g., Multi-Level Protection Scheme Level 3), contact 138’s official support for tailored configurations.
